Aerodynamics is a huge and very interesting subject. A close friend of mine develops small scale radio controlled speed run cars. Building and racing 1/12, 1/10 and 1/8 scale vehicles at over 100MPH is not as easy as some may think. One current project even uses active giro assisted steering, electronically adjustable spoiler and rear wing providing live micro fine control of aerodynamics and downforce. When You are changing the surface roughness of the paint on specific sections of a body shell to gain an extra one or two MPH You know it's going to be a fun week. Often wished we had a wind tunnel to test the RC cars in as doing all testing and development outdoors, effectively on track R&D, makes it so much harder to get consistent data but after seeing some of the complexity of wind tunnel calibration issues maybe we are better off with live outdoor testing. Always very interesting to hear from professionals who live and breath aerodynamics. Thank You for these excellent videos Sir. Keep up the good work.
Super detailed piece Scott. The information gained from U're vids comes in F1 increments. Little more here, a little more there. There's always something new to add to the picture. Many thanx & as always, best regards 👍👍
That was the best video about F1 aero I’ve ever seen. I’m so sick of being shown details of floor skirts and wings etc to try and get excited about each teams’ updates but this was informative.
Wow, what a great video. The explanations of how a wind tunnel works and all the factors that need to be taken into account for accurate data really helped me to understand the aero of these new (2021 and beyond) F1 car designs. Thanks!
Thanks for the explanation! Brought me back to the old days when I took two fluids courses in my undergrad. It sure explains also why the ground-effect F1 cars are just so sensitive, especially to floor damage.
as much as i"d like more different colour schemes, the worst "special livery" to me was the carbon themed Ferrari, which didn"t feature any more exposed carbon than usual.
@@bythelee maybe just the red paint weighs 40 grams but that doesn’t mean that ALL the pInt weighs 40 grams. All the paint probably weighs 4-6kg. I’m saying get rid of all the paint, thats a massive savings.
Wow I actually did a project on the Prandtl Boundary Layer for a fluid mechanics module at university around 5 years. Haven’t heard it mentioned since then until now.
"Deliciuously Complicated" reflects EXACTLY the challenges of full scale correlation aerodynamics. Kudos on your excellent video and to Wilhelm for his super insightful comments.
So basically, they made a massive change to their whole testing procedure, without verifying specifically how this will impact data collection. Seems like a massive oversight from everyone there
It's a lack of institutional knowledge. The industry figured this out in the 80s, but by the 2020s, all those people likely retired. Few people were around to remember why they wanted the rough belt. And if they did remember, they might have thought they could try and run calculations to fix it.
@@lazydictionary Eh, I think it is probably the latter. I highly doubt top tier engineers working for F1 teams don't understand or know about these concepts. They probably just thought they knew better and could account for the variables in their calculations. They possibly had pressure put on them by Mercedes to keep costs and complexity down as well. Who knows though.
Worked briefly at Mercedes F1 (Old Honda) in Brackley for the 2012 car. Amazing facility, Brawn would walk around the office and it was the days when Schumacher was still racing. Good times
This should have been titled as a generalised wind tunnel & aerodynamics education piece, the Mercedes angle was just wedged into the last 2 minutes to give the video a clickable title
youtubers need to please the algorithm to get their videos shown, blame youtube. i would absolutely complain about a youtuber being clickbaity were it entirely unnecessary, but the algorithm gods must be worshipped if youtubers dont want their channels to just stop getting promoted
Could you maybe interview willem on how their workflow is, like which programs they use and how (like its said mercedes is using star ccm+, redbul is using ansys and williams openfoam etc) but how do they test and compare stuff to their windtunnel runs, how do they improve, how fine is their mesh (the "accuracy" how their model before doing cfd tests), do they use math or some sort of trial and error shapes if testing new parts for certain areas of the car etc. This is nerdy but super interesting!
Turbulence per se is not a bad thing. In fact, turbulent boundary layers are prefered in areas where strong adverse pressure gradients exist to help avoid separation. You confuse turbulence and separation.
A brilliant video explaining some complex stuff so that even I think I understand. I now understand what a lamena flow wing is and some of the stuff my flying instructor tried to teach me about drag. Thank you
If only something like fluidjobs existed 5yrs ago when I graduated, I would maybe be somewhere completely different than I am now... But where I'm moving, there is sadly very few to none motorsport entities, and remote jobs are not quite numerous in the industry. Thanks to all the team for the video!
Great content for a technically minded fan. Loved hearing about some of the more detailed aspects of running a wind tunnel, and linking that to Merc's performance issues. A nice alternative to hearing Toto or Lewis giving their view of things, that is obviously from a substantially different perspective.
1977: Lotus founder Colin Chapman realized - thanks to a mistake in the manufacture of the side pods of the JPS78 Formula 1 car - that by putting a flexible slat on the bottom outside edge of the side pods, the car cornered significantly faster than without them - as standard F1 cars of the day only had wings for aerodynamic aids at both ends back then. It ultimately led to the JPS79 that gave both Mario Andretti and the late Ronnie Petersen the fastest (if not the most reliable) car in F1 leading to Andretti winning the driver's championship, Petersen (who had passed away from injuries sustained in the Italian GP) posthumously securing second place, and Team Lotus securing the 1978 Constructer's championship.
I find it really interesting that redbull went with the zero pod concept this year (Albeit less extreme) and it also ended their dominance. (Also less extreme) I wonder what was so appealing about the concept that even after Merc failed they decided to pursue it
I Studied Mech Eng at University in the early seventies and the only two modules I really enjoyed were Fluid Mechanics and Software Engineering (this was before IT based degrees). I went off to a career in IT with IBM when many of my fellow students went off to join the likes of Rolls Royce (Aero-engines). It was early in the days of Fluid Mechanics. Videos like this interest me a lot and make me wonder where my life would have gone had I chosen Fluid Dynamics rather than IT as a career.
More than 16 minutes into a 19 minute video, you finally describe the problem from the video title. You make very useful content but the title is misleading clickbait.
I was frustrated by this too. And the answer only took a couple minutes to explain. Plus there were two host read advertisements and three TH-cam advertisements during the video. Way too many.
I think you misunderstand the whole video. Fluid dynamics is a very complicated topic and you cannot condense it into 3 minute video. The context that Scott provides is actually very important to the conclusion.
It's like when Uni students are complaining that they have to take "bullshit" courses like math and physics in the first few semesters. It's needed to understand the ones that they really want to study. The first 16 minutes (expect the ads) are needed to fully understand the last 3 minutes
Sounds good. A lot of talk about the rolling road and boundary layer air. But, the facts are that a 60% model in a wind-tunnel with air moving ONLY at 120 MPH will just give you data related to the full size vehicle traveling at 72 actual MPH! Mercedes created a great "lifting-body" design for their 2022 entry into F1.
What does this teach us: A good driver (like Lewis) only becomes champion if he is backed by the best engineers. If the engineers make a mistake, no matter "how great" that driver is, he cannot push that car to do miracles and win championships. In other words, Lewis was lucky to drive a Mercedes and not a Haas in the years when he won.
This is not news though. The competition for the drivers is not fair and never was. That's the result of the technical arms race we all love and enjoy seeing.
WHAT A TOPIC!!!! F1 AERODYNAMICS!!!! YESSS!!! Actually, I was talking with one of my peers engineers of my work about the MB F1 that is the Power Unit Supplier for McLaren and Williams F1 and I was saying what Aerodynamics was so important in F1 and I used the comparison between McLaren and MB F1 cars… Using the same Power Unit and look what McLaren was capable to do with the Aerodynamics upgrades…. That’s what I love F1 but specially, AERODYNAMICS!!! And @Driver61 and Scott Mansell bring to us!!! So, BIG CONGRATULATIONS TO YOU SIR SCOTT MANSELL Sir Williem Toet! Big Fan of Mr. Williem Toet!!! I have been following him since late 80’s….
Rigorous and detailed engineering/physics dialog. Good on you! Could you add a piece about the actual changes to the sidepods, T-tray, and bottom plate throughout their engineering recovery from porposing. Go Hamiton!

Gemini summarized this: Mercedes' wind tunnel testing issues that caused their F1 dominance to end in 2022 were due to the following reasons: Rolling Road Surface Roughness: The team used a smoother Rolling Road surface than the actual track, which led to inaccurate data on how the car's aerodynamics would behave in real-world conditions. Limited Testing Time: Mercedes was restricted to 36 wind tunnel runs per week in 2021 due to the aerodynamic testing regulations, which made it difficult to conduct enough reference runs to calibrate their data." Focus on Performance over Calibration: In order to maximize their limited testing time, Mercedes prioritized performance testing over calibration runs, which led to further inaccuracies in their data. These issues combined to give Mercedes a false sense of confidence in their car's performance, which led to them making poor design choices that ultimately ended their dominance.
The company I worked in the nineties made the control to get the road running with extreme high precision. Normally side control precision was well below 0.1mm. And tension even more accurate. High tech by itself, even looking so simple.
I have a masters in aero and all these principles are pretty basic and we learn them in year 1-2 of school. This won’t be where Mercedes messed up, it will be far more complex.
One of the coolest things about F1 is how knowledge and technologies from F1 can make its way to normal road cars, making them better and safer. Anyone that's old enough (and lived where there is a lot of snow/ice) remember having to "pump the breaks" when sliding, along with a bunch of other driver skills and experience. You had to drive differently, and if you didn't, you could slide off the road. Today, SUV's/Crossovers have packages that help with all of this so that - some - of those special skills/knowledge used in winter driving aren't necessary. I say some because you still see drivers in the ditch, hung up in the snow. So, slow down.
There are limits on Computational Fluid Dynamics (CFD) generally cadence fidelity. 25 Tflops I think depending on the last season manufacturer position.
@@lolomgwtfbbqqqq they did a wrong upgrade in Barcelona 2023 apparently, when they had the least time and even less with the penalty, so yes it affected them as well
@@lolomgwtfbbqqqq bro go read some articles, im not just talking shit, what did you think? and if that doesnt convince you, just look only one year later for the obvious effect
I realized last races that their wind tunnels also miscalculated badly air density and temperature , a common flaw in many wind tunnel operations. 3C affects aero by 1% so we can imagine how that affected randomly many teams depending the air temperature thrown at the model even in a closed circuit wind tunnel… it became clear that all factors equal the Mercedes optimal loading and drag is in colder days…
I‘m sure you know all the basics of aerodynamics to understand the conclusion. For all orhers it is important to understand WHY the road surface has this influence
You mix two things related to the boundary layer and tturbulance. As you mentioned the boundery layer has two "forms", de laminair flow and turbulant flow. You show this correctlt in your drawing. What you missed in this drawing is the size of the wake. With the turbulant boundary layer the wake is smaller. This is because the turbulant boundery layer transmits energy throughout the layer and stays longer connected to the surface. The wake portion of this drawing is what creates the actual turbulance behind the car you mentioned. You also mentioned that the turbulant boundery layer is much more difficult to predict (compared to the laminair airflow), this is also the opposite. A laminair airflow is detaches earlier, but also attaches again. This creates a fluctuating airodynamic load. A turbulant boundary layer stays connected longer and the seperation is delayed and therfor much more predictable. The seperation point can also be fixed on a fysical location with carefully pladed structures. On a wing this is usually the rear edge, But you can also see at the front of a wing (or other structures) a dedicated mechanical provision to change the boundery layer from laminair to turbulant. This has been succesfully used in speedscating with carefully placed strips on the head and legs. On the front of wing surfaces of airplanes vortex generators are placed to ensure enough energy is available in the boundary layer to ensure a predictable airflow.
Turbulent flow isn't that hard to predict, to be honest. The part that really makes it difficult is when you have a laminar flow that transitions to turbulent, because that transition is unsteady. Because it's unsteady and cars depend so much on flow conditioning, that sometimes it's better to simply induce the turbulence yourself. Sometimes consistent but lower energy flow works better than inconsistent but potentially higher energy flow. Better the devil you know, than the one you don't type of thing.
That's so true. In chemical engineering and design you either stay trully laminar or stay the ?#&#^ away from the transient region in developed turbulent.

The same principle is used on the leading edge root extensions you see on fighter aircraft, where they intentionally create a vortex near the wing root to force the air flowing over the wing a bit closer to the wing, which serves the quadruple purpose of creating a vortex of fast flowing air providing a bit of negative pressure which further increases lift at high angles of attack, delaying flow separation past the usual stall points, which improve low speed maneuverability and predictability of the air flowing over the wing at low speeds, and making the plane look cool as hell. Some race cars also have vortex generators over convex portions of their exterior for the same purpose - it's better to trip the flow into turbulent flow at a predictable location than to have the transition point vary depending on many tiny factors, some of which are impossible to account for, such as the temperature of the surface or the amount of dirt that has built up on the car since it had last been washed.
@@kelly2631 You have to be careful with vorticity, since the phenomenon has tremendous amounts of hysteresis. That same hysteresis that delays separation during high AoA also causes drag, and once disturbed require more energy than the initial conditions to re-establish it to a previously stable state. Vorticity, like magnetism retains a memory of past vorticity.
@@mrbungle3310 caps aren't artificial. It forces you to be better, not just spend more. Before all of these caps, the wealthiest teams were the best teams.
So after all the Mercedes instigated politics of 2022 peaking at Baku, all they had to do was raise the ride height?? It's almost as if Merc were simply trying to get rules changed to suit their needs. Who'd have thought!

Building and racing 1/12, 1/10 and 1/8 scale vehicles at over 100MPH is not as easy as some may think. One current project even uses active giro assisted steering, electronically adjustable spoiler and rear wing providing live micro fine control of aerodynamics and downforce. When You are changing the surface roughness of the paint on specific sections of a body shell to gain an extra one or two MPH You know it's going to be a fun week. Often wished we had a wind tunnel to test the RC cars in as doing all testing and development outdoors, effectively on track R&D, makes it so much harder to get consistent data but after seeing some of the complexity of wind tunnel calibration issues maybe we are better off with live outdoor testing. Always very interesting to hear from professionals who live and breath aerodynamics. Thank You for these excellent videos Sir. Keep up the good work.
That was an awesome video, I love data, analysis and trying to understand why, how etc.. but i never thought about that. Thanks Willem !
Super detailed piece Scott. The information gained from U're vids comes in F1 increments. Little more here, a little more there. There's always something new to add to the picture. Many thanx & as always, best regards 👍👍
Outstanding video. An incredibly complicated subject explained reasonably simply.
In the last 3 mins...
The 'How' starts at 16:41
Yeah, this was brutal. Watched the whole thing and basically it's, Mercedes used a smooth road instead of a bumpy one.
That was the best video about F1 aero I’ve ever seen. I’m so sick of being shown details of floor skirts and wings etc to try and get excited about each teams’ updates but this was informative.
Honestly never knew how complicated it was building an f1 car and getting the aero working together top video 👌🏻
One of the best technical videos I have watched made for fans. Thank you!!
Wow, what a great video. The explanations of how a wind tunnel works and all the factors that need to be taken into account for accurate data really helped me to understand the aero of these new (2021 and beyond) F1 car designs. Thanks!
You got me at "deliciously complicated". Thanks, it was a great video.
Thanks for the explanation! Brought me back to the old days when I took two fluids courses in my undergrad. It sure explains also why the ground-effect F1 cars are just so sensitive, especially to floor damage.
The 22 cars had so much more colour! Bring back fully painted cars through a weight allowance in the next regs
@@apc9681 I’d rather have full carbon cars with stickers here and there. Save on weight and look even cooler
as much as i"d like more different colour schemes, the worst "special livery" to me was the carbon themed Ferrari, which didn"t feature any more exposed carbon than usual.
@@illdeletethismusic make it all black then you’re talking 😎
Given that a completely red Ferrari has 40 grams of red paint on it, I'd say the weight is not a factor in choosing the color scheme.
@@bythelee maybe just the red paint weighs 40 grams but that doesn’t mean that ALL the pInt weighs 40 grams. All the paint probably weighs 4-6kg. I’m saying get rid of all the paint, thats a massive savings.
I love that you don't overly water this down, so good to have more in depth videos
Wow I actually did a project on the Prandtl Boundary Layer for a fluid mechanics module at university around 5 years. Haven’t heard it mentioned since then until now.
"Deliciuously Complicated" reflects EXACTLY the challenges of full scale correlation aerodynamics. Kudos on your excellent video and to Wilhelm for his super insightful comments.
You have too many ads.
Good stuff, Scott. This is the first of your videos I've had to watch twice to even get close to understanding the subject.
Any update on the updside down run?
never going to happen
it was always going to end in tears
Here we go again. He is waiting for funding, it's going to take more than a year.
@@emenesu he should fold and let redbull sponsor it, otherwise its probably going to be never happen
@@emenesu Here we go again - people being impatient with other people asking questions.
I've been anticipating this video for the last 3 years. The road surface laminar airflow was an eye opener though. Salute!
So basically, they made a massive change to their whole testing procedure, without verifying specifically how this will impact data collection. Seems like a massive oversight from everyone there
It's a lack of institutional knowledge. The industry figured this out in the 80s, but by the 2020s, all those people likely retired. Few people were around to remember why they wanted the rough belt. And if they did remember, they might have thought they could try and run calculations to fix it.
@@lazydictionary Eh, I think it is probably the latter. I highly doubt top tier engineers working for F1 teams don't understand or know about these concepts. They probably just thought they knew better and could account for the variables in their calculations. They possibly had pressure put on them by Mercedes to keep costs and complexity down as well. Who knows though.
I have a sneaking suspicion MBA style folks like Toto are to blame
Worked briefly at Mercedes F1 (Old Honda) in Brackley for the 2012 car. Amazing facility, Brawn would walk around the office and it was the days when Schumacher was still racing. Good times
That sir was the best in-depth explication of wind tunnel correlation I have seen.
This should have been titled as a generalised wind tunnel & aerodynamics education piece, the Mercedes angle was just wedged into the last 2 minutes to give the video a clickable title
Sad...
The life of a youtuber
And they are basing their facts on the opinion of a guy who wasn’t even there.
Amazing complaints 🙄
youtubers need to please the algorithm to get their videos shown, blame youtube. i would absolutely complain about a youtuber being clickbaity were it entirely unnecessary, but the algorithm gods must be worshipped if youtubers dont want their channels to just stop getting promoted
love the fluid dynamics dive. A series going in-depth on the aerodynamics as well as testing and development of f1 cars would be amazing.
Could you maybe interview willem on how their workflow is, like which programs they use and how (like its said mercedes is using star ccm+, redbul is using ansys and williams openfoam etc) but how do they test and compare stuff to their windtunnel runs, how do they improve, how fine is their mesh (the "accuracy" how their model before doing cfd tests), do they use math or some sort of trial and error shapes if testing new parts for certain areas of the car etc. This is nerdy but super interesting!
Video starts at 16:15
You're a legend !
thank you so much
Thankyou for your service and screw thus guy
Thank you!!
Thanks mate, this guy really thought talking nonsense for 16 minutes was alright
Turbulence per se is not a bad thing. In fact, turbulent boundary layers are prefered in areas where strong adverse pressure gradients exist to help avoid separation. You confuse turbulence and separation.
A brilliant video explaining some complex stuff so that even I think I understand. I now understand what a lamena flow wing is and some of the stuff my flying instructor tried to teach me about drag. Thank you
After this video I appreciate the descriptor "deliciously complicated." That alone was worth the watch (everything else was great too).
I came to write a similar comment. You could hear the passion in his voice as he was saying it. Good stuff
0:12 they weren’t allowed to spend $400 million + on there car …
they was before covid
On catering? Like red bull
Their*
And they're not allowed to do 1000 km of secret tyre tests and get away with it anymore, the FIA has found new toys to play with 😂
If only something like fluidjobs existed 5yrs ago when I graduated, I would maybe be somewhere completely different than I am now... But where I'm moving, there is sadly very few to none motorsport entities, and remote jobs are not quite numerous in the industry.
Thanks to all the team for the video!
As a Future Aerodynamicist for the FERRARI F1 TEAM(my dreams) the term "Air Flow Sandwich" sounds delicious
hope the contract comes with a good therapist
Thanks. I was only wondering the other day if wind tunnels have evolved to allow for pitch & yaw etc. the other week!
2 ad reads in 5 minutes is wild
Remember 2008 when selling anything on the netwant you were a sellout for the man
Great content for a technically minded fan. Loved hearing about some of the more detailed aspects of running a wind tunnel, and linking that to Merc's performance issues. A nice alternative to hearing Toto or Lewis giving their view of things, that is obviously from a substantially different perspective.
1977: Lotus founder Colin Chapman realized - thanks to a mistake in the manufacture of the side pods of the JPS78 Formula 1 car - that by putting a flexible slat on the bottom outside edge of the side pods, the car cornered significantly faster than without them - as standard F1 cars of the day only had wings for aerodynamic aids at both ends back then. It ultimately led to the JPS79 that gave both Mario Andretti and the late Ronnie Petersen the fastest (if not the most reliable) car in F1 leading to Andretti winning the driver's championship, Petersen (who had passed away from injuries sustained in the Italian GP) posthumously securing second place, and Team Lotus securing the 1978 Constructer's championship.
Excellent visual explanation of the differences between laminar and turbulent fluid flow.
Your fluid mechanics lecture was more than all the classes I've attended in my college
I learned a tremendous amount from this! Thank you for putting such excellent explainers up for us.
Just on a completely different note, my boi Red Bull still rocking a World War wind tunnel
More of a Cold war era wind tunnel, that has since had 2 major component upgrades too
@@into_the_void It still nearly falls apart, google mk7 redbull windtunnel, ofcourse they use modern equip, but only modern equip that fits
It was used to design the RAF's Tornado fighter plane
@@quadrantalerror1121
Not the Spitfire?? 🙂
I find it really interesting that redbull went with the zero pod concept this year (Albeit less extreme) and it also ended their dominance. (Also less extreme) I wonder what was so appealing about the concept that even after Merc failed they decided to pursue it
amazing that this channel has 1.27m subscribers but the contents are mostly just touching the surface of basic engineering and technologies.
I Studied Mech Eng at University in the early seventies and the only two modules I really enjoyed were Fluid Mechanics and Software Engineering (this was before IT based degrees). I went off to a career in IT with IBM when many of my fellow students went off to join the likes of Rolls Royce (Aero-engines). It was early in the days of Fluid Mechanics. Videos like this interest me a lot and make me wonder where my life would have gone had I chosen Fluid Dynamics rather than IT as a career.
More than 16 minutes into a 19 minute video, you finally describe the problem from the video title. You make very useful content but the title is misleading clickbait.
Welcome to TH-cam where clickbait is the new normal
I was frustrated by this too. And the answer only took a couple minutes to explain.
Plus there were two host read advertisements and three TH-cam advertisements during the video. Way too many.
I think you misunderstand the whole video. Fluid dynamics is a very complicated topic and you cannot condense it into 3 minute video. The context that Scott provides is actually very important to the conclusion.
Fast forward to where you want then. I enjoyed the context. So for me, GFC, and theres a reason hes got a channel and you don't. ESAD
It's like when Uni students are complaining that they have to take "bullshit" courses like math and physics in the first few semesters. It's needed to understand the ones that they really want to study. The first 16 minutes (expect the ads) are needed to fully understand the last 3 minutes
Sounds good. A lot of talk about the rolling road and boundary layer air.
But, the facts are that a 60% model in a wind-tunnel with air moving ONLY at 120 MPH will just give you data related to the full size vehicle traveling at 72 actual MPH!
Mercedes created a great "lifting-body" design for their 2022 entry into F1.
What does this teach us: A good driver (like Lewis) only becomes champion if he is backed by the best engineers. If the engineers make a mistake, no matter "how great" that driver is, he cannot push that car to do miracles and win championships. In other words, Lewis was lucky to drive a Mercedes and not a Haas in the years when he won.
Very true. But don’t forget the checo-Redbull side of the same coin! Just because you have a quality car doesn’t mean you’re guaranteed success
And Max was lucky because only Redbull nailed ground effect cars and no one was able to catch until now which is Losing every race .
At the end of the day, to win a championship, you need the best driver in the best car. One doesn’t work without the other.
@@sadushukle2141 That's pretty self evident for any example for that matter, irrespective of it being Lewis-Mercedes or Verstappen-Red Bull.
This is not news though. The competition for the drivers is not fair and never was. That's the result of the technical arms race we all love and enjoy seeing.
WHAT A TOPIC!!!! F1 AERODYNAMICS!!!! YESSS!!! Actually, I was talking with one of my peers engineers of my work about the MB F1 that is the Power Unit Supplier for McLaren and Williams F1 and I was saying what Aerodynamics was so important in F1 and I used the comparison between McLaren and MB F1 cars… Using the same Power Unit and look what McLaren was capable to do with the Aerodynamics upgrades….
That’s what I love F1 but specially, AERODYNAMICS!!! And @Driver61 and Scott Mansell bring to us!!!
So, BIG CONGRATULATIONS TO YOU SIR SCOTT MANSELL Sir Williem Toet! Big Fan of Mr. Williem Toet!!! I have been following him since late 80’s….

Just what a bot would say
So many ads
Outstanding video as usual! Very thorough and the detail is exactly why I love this sport!
It would be great to see this kind of wind tunnel testing done on the Rally 1 WRC cars to understand their sideways grip and also how they jump.
Rigorous and detailed engineering/physics dialog. Good on you! Could you add a piece about the actual changes to the sidepods, T-tray, and bottom plate throughout their engineering recovery from porposing. Go Hamiton!
Very informative and no music over voice. Thanks.
That Conveyor-Belt moving @180 is *nuts* Pretty cool you can also Steer too

This is one of the more captivating videos recently. Really nice story telling and lead in to the conclusion. It was really enjoyable.
Gemini summarized this:
Mercedes' wind tunnel testing issues that caused their F1 dominance to end in 2022 were due to the following reasons:
Rolling Road Surface Roughness: The team used a smoother Rolling Road surface than the actual track, which led to inaccurate data on how the car's aerodynamics would behave in real-world conditions.
Limited Testing Time: Mercedes was restricted to 36 wind tunnel runs per week in 2021 due to the aerodynamic testing regulations, which made it difficult to conduct enough reference runs to calibrate their data."
Focus on Performance over Calibration: In order to maximize their limited testing time, Mercedes prioritized performance testing over calibration runs, which led to further inaccuracies in their data.
These issues combined to give Mercedes a false sense of confidence in their car's performance, which led to them making poor design choices that ultimately ended their dominance.
The company I worked in the nineties made the control to get the road running with extreme high precision. Normally side control precision was well below 0.1mm. And tension even more accurate. High tech by itself, even looking so simple.
you did two midroll ads before 7 minutes? Bro, I gotta leave. I'm not hear for more commercials than a f1 production.
Just skip forward with the tap of a finger it’s not hard
Fast forward. How’s he supposed to earn a living doing this for free on TH-cam???
Truly Great “Stuff”!!!
Your presentation is invaluable.
Thank you 🏎️🏁
I have a masters in aero and all these principles are pretty basic and we learn them in year 1-2 of school. This won’t be where Mercedes messed up, it will be far more complex.
One of the coolest things about F1 is how knowledge and technologies from F1 can make its way to normal road cars, making them better and safer. Anyone that's old enough (and lived where there is a lot of snow/ice) remember having to "pump the breaks" when sliding, along with a bunch of other driver skills and experience. You had to drive differently, and if you didn't, you could slide off the road. Today, SUV's/Crossovers have packages that help with all of this so that - some - of those special skills/knowledge used in winter driving aren't necessary. I say some because you still see drivers in the ditch, hung up in the snow. So, slow down.
WHAT, they limit the times they can do research???????!!!!!!! Thats nuts
Paraphrasing, yes, they limit (very expensive) wind tunnel time and thus money. Same money = more equal chances more level playing field.
There are limits on Computational Fluid Dynamics (CFD) generally cadence fidelity. 25 Tflops I think depending on the last season manufacturer position.
@@l.d.t.6327who cares how level the playing field is though??
@@disgruntledwookie369 “who cares” -> not me.
Interesting, so they're trying to limit throw money at the problem until there is no problem. Thats awesome.
I love these videos, I am learning so much so thank you for that, and keep it up!
"Deliciously complicated" 😂
loved this video! very interesting how seemingly small things can make such a big difference!
So the ATR allocation did its job perfectly
Doesn’t explain why red bull did well
@@lolomgwtfbbqqqq Adrian Newey doesn't need a wind tunnel. He draws on his drafting table and his mind simulates the airflow.
@@lolomgwtfbbqqqq they did a wrong upgrade in Barcelona 2023 apparently, when they had the least time and even less with the penalty, so yes it affected them as well
@@NeumannKlaus you're seriously going to reference 2023? The year when redbull won every single race except 1?
@@lolomgwtfbbqqqq bro go read some articles, im not just talking shit, what did you think? and if that doesnt convince you, just look only one year later for the obvious effect
Fantastic video, the best on aerodynamics easy to understand that I’ve seen. Subscribed.
I realized last races that their wind tunnels also miscalculated badly air density and temperature , a common flaw in many wind tunnel operations. 3C affects aero by 1% so we can imagine how that affected randomly many teams depending the air temperature thrown at the model even in a closed circuit wind tunnel… it became clear that all factors equal the Mercedes optimal loading and drag is in colder days…
19 minutes long for a point that can be conveyed in 1 minute.
"How Wind Tunnels Are Used by F1 Teams" would be a more fitting title
I‘m sure you know all the basics of aerodynamics to understand the conclusion. For all orhers it is important to understand WHY the road surface has this influence
You mix two things related to the boundary layer and tturbulance. As you mentioned the boundery layer has two "forms", de laminair flow and turbulant flow. You show this correctlt in your drawing. What you missed in this drawing is the size of the wake. With the turbulant boundary layer the wake is smaller. This is because the turbulant boundery layer transmits energy throughout the layer and stays longer connected to the surface. The wake portion of this drawing is what creates the actual turbulance behind the car you mentioned. You also mentioned that the turbulant boundery layer is much more difficult to predict (compared to the laminair airflow), this is also the opposite. A laminair airflow is detaches earlier, but also attaches again. This creates a fluctuating airodynamic load. A turbulant boundary layer stays connected longer and the seperation is delayed and therfor much more predictable. The seperation point can also be fixed on a fysical location with carefully pladed structures. On a wing this is usually the rear edge, But you can also see at the front of a wing (or other structures) a dedicated mechanical provision to change the boundery layer from laminair to turbulant. This has been succesfully used in speedscating with carefully placed strips on the head and legs. On the front of wing surfaces of airplanes vortex generators are placed to ensure enough energy is available in the boundary layer to ensure a predictable airflow.
Turbulent flow isn't that hard to predict, to be honest. The part that really makes it difficult is when you have a laminar flow that transitions to turbulent, because that transition is unsteady. Because it's unsteady and cars depend so much on flow conditioning, that sometimes it's better to simply induce the turbulence yourself. Sometimes consistent but lower energy flow works better than inconsistent but potentially higher energy flow. Better the devil you know, than the one you don't type of thing.
That's so true. In chemical engineering and design you either stay trully laminar or stay the ?#&#^ away from the transient region in developed turbulent.
kind of sacrificial turbulent flow, if you will.

.................STOP BLAME MERCEDES......JUST stop...THEYRE GOOD GUYS......EVEN WHEN THEY WERE KINDA bad.........
The same principle is used on the leading edge root extensions you see on fighter aircraft, where they intentionally create a vortex near the wing root to force the air flowing over the wing a bit closer to the wing, which serves the quadruple purpose of creating a vortex of fast flowing air providing a bit of negative pressure which further increases lift at high angles of attack, delaying flow separation past the usual stall points, which improve low speed maneuverability and predictability of the air flowing over the wing at low speeds, and making the plane look cool as hell.
Some race cars also have vortex generators over convex portions of their exterior for the same purpose - it's better to trip the flow into turbulent flow at a predictable location than to have the transition point vary depending on many tiny factors, some of which are impossible to account for, such as the temperature of the surface or the amount of dirt that has built up on the car since it had last been washed.
@@kelly2631 You have to be careful with vorticity, since the phenomenon has tremendous amounts of hysteresis. That same hysteresis that delays separation during high AoA also causes drag, and once disturbed require more energy than the initial conditions to re-establish it to a previously stable state. Vorticity, like magnetism retains a memory of past vorticity.
Awesome video!! I greatly appreciate the depth of the subject matter! Very well explained and written!
This was a good thing. No sport should have such dominance that it eliminates any competition.
It shouldn't be artificial tho
F1 is an engineering championship, with the budget cap in place let the most efficient and best engineers win
@@mrbungle3310 caps aren't artificial. It forces you to be better, not just spend more. Before all of these caps, the wealthiest teams were the best teams.
What about real Madrid's?
Whenever they are not winning is such a bleep in the system I suppose?😂😂
Are you joking, look what’s happened since ? Another team is dominating so surly we would have been better off with a strong Mercedes?
Thank you for this fascinating look into wind tunnel use. I knew it was complex, I just didn't realise it was comparable to saying Space is big, haha
Skip to 16:00 to hear about merc.
So after all the Mercedes instigated politics of 2022 peaking at Baku, all they had to do was raise the ride height?? It's almost as if Merc were simply trying to get rules changed to suit their needs. Who'd have thought!
Witch they did and screwed the intent of the rules, with was better car following
All that printing Toto did and he still ended up having to change the fucking car
4:45 just glazes over the fact the FAA regulates air speed...indoors...on the ground.
Indeed.

Yes the color of the kislux is beautiful and it is a great decision, maybe one day they will add feet and straps. It would be nice to have a bigger bag during the colder months when we have to store gloves, beanies, scarves, etc…
