How the 2022 F1 Aero Tunnels Actually Work
ฝัง
- เผยแพร่เมื่อ 17 ม.ค. 2022
- So those old flat floors are out - and well now we have aero tunnels - and strap in - these are genius. I’m so excited for these aero-tunnels man.
And these, rather than a flat floor and this ‘kick line’ that ramps up into the diffuser. So flat floor with air being pulled through by a large diffuser.
Now, we’re going to have these sort of three-part tunnels
throat so you'll have this bit by the side of the cockpit where you have a ramp section going down converging and then you have a section which i've described in some of my drawings as a flat floor it's not strictly flat it's kind of curved then you're then allowed to have a much bigger effectively a diffuser which is just an even bigger tunnel starts much earlier
if we go back to the journey of the air going under the floor the air will arrive at the front of the car so the air will arrive pretty much untouched and then go into this converging section and it will start to accelerate as it goes into this converging section until you reach that first kick line and this is where you'll get the first burst of downforce the first burst of really low pressure the air will then continue to accelerate under that middle flatter section of floor

On the previous cars this would create loads of dirty air that made life much worse for the car behind - it came out the rear of the car very low and spread wide by all the outwash.
now what you'll have is the tunnels will end with the beam wing which is the lower rear wing which is of quite strong quite a powerful wing and then you'll have this big curved upper wing and these will all collect the airflow that comes out of the diffusers and then push it upwards and eventually outwards which they describe it is the mushroom
This actually lifts the dirty air up and above the car behind - genius!

@@Firebolt1729 LoL! She's spamming and is in virtually every possible comment on this video.
@@Jojo_Bee i thought her comment was insightful to the new 2022 regs
I'm an optimistic pessimist. I've seen all of the maFIA's promises of closer competition since the 80's go awry.
@@AndyFromBeaverton Ha, yes, you are correct sir. They've been promising closer racing since I started watch in 2005. Still waiting, lol. I'm pretty sure once everyone has a grasp of their new car, they will manipulate them somehow for more downforce and, most likely, more dirty air coming off the back. That's usually what happens. Also, I wonder how the Mercedes car, and others, that use the rear suspension to lower the car to the point it stalls the floor and diffuser are going to work with no real aero pushing down the car, when they brake into a high speed corner. Sorry to say, but maybe it's time they spec the cars out more to be similar in performance. Then we'll see who the real best driver is. Anyone think Hamilton would have won 6 drivers titles with Williams? No. But, he can have the one with McLaren because I'm a McLaren fan, lol. We wouldn't be calling him the best then. He drove the best car, so it made him the best. Alonso, Vettel, Raikkonen, could have, most likely, done the same with his cars. Especially Alonso.
I'll be interested to see what happens if they ride the curbs and the impact that might have on the aero underneath the car. I can't see the 2022 cars being as aggressive on the curbs if its going to massively impact downforce
The big kerbs need to go anyway. Too many accidents already because of them.
Won't make much difference in my opinion (for the title contenting cars atleast), I saw that the tunnels are mounted on the chassis that remains stationary the suspension absorbs most of the bumps and the tunnels aren't rubbing the ground like they did in the 70's rather these tunnels are lifted and are sealed via aerodynamics. So how well these tunnels are sealed I think will be the difference of performance.
Indy cars have had tunnels like this since forever and they have no problems with curbs. So don't worry, F! designers aren't going to let themselves be bested by us American hicks.
@@khawajabasit977 There's no such thing as a stupid question but sometimes I really wonder if these people even watch f1. I'm not picking on you but the original poster. Do current cars lose downforce when they curb ride? No. Why? Suspension. Suspension or more accurately ride height managers.
@@Bahamuttiamat Depends if your 'curb ride' involves some bounce that the suspension can't fully absorb which does happen so the OP's question is good. Anyway the drivers are going to have to avoid anything that will disturb the ride height because, obviously, ground effects is height crucial.
They'll create vortices in a way it will seal the floor of the car. What I am also curious is the amount of design work and loopholes in tech regs engineers will find in order to design better, more efficient, Venturi tunnels and diffusers
The ground effect actually also occurs on ships when they are just above the bottom of a canal for example. They get sucked down to the bottom.
I;ve never noticed downforce, but the concept suddenly made sense to me while canoeing down a river, the current is stronger in the shallow areas then slows down when it gets deeper, There are other ways to exolain it but that's what made it real to me.
You also get ground effect in aviation, in a reverse manner. Helicopters use it a lot to stay stanionary while close to the ground, while planes can use it to get of the ground earlier and build up speed before the climb (that's not really standard procedure tho), or during the flare on touchdown !
or too close to the side of a canal - see Ever Given, Suez
@@Ked_gaming The Ekranoplan planes are the coolest example imo
Hate to get a bit too technical here but the "ground effect" in F1 is just the venturi effect. Which is what happens with canoes and evergiven.
Helicopters and ekranoplans are what aerodynamicists know as ground effect.
Ideally, a team would build a car that has lovely ground-effect downforce, and a nasty wake to make following and overtake a headache, thus negating the change.

The rules have been designed to try and prevent that. While teams will be trying to do this, the FIA has made it very clear that they will ban anything that undermines that philosophy.
There is a limit of dirty air a car can produce
Dirty Air is just F1 terms of "Aerodynamic Drag".
From here, less dirty air generated also make the car more slippery. There's no point adding it back anyway, even if you are Ferrari
Somebody got viruses on their phone lol
Really interesting and well explained. Nice to see Callum presenting and great, vibey production value as always : )
Can't wait for the first wet race were the cars produce mushroom clouds behind them... In all seriousness, the way the diffuser anfd the rear wing is desingned I feel like this will massively incerease the already big problem of spray in wet races. Also the cars will hoover a dry line in like 2 laps after rain stops I guess.

Really great explanation of ground effects and aero tunnels!! Love it!

Much love
Finally! Haha i waited so long for this Video and it was so worth it! Thank you
Amazing. Lots of words. Cars fast. Thank you!
Great job, Callum. Very entertaining and educational. 👍
Turbocharged, ground effect F1 cars…all we are missing now is active suspension for F1 to look like all the doodling looked like in my mid 90’s school books…
yeah, FRIC needs to comeback
It was considered for this year so maybe 2026 we could see it
And active aerodynamics imagine those wings morphing in the straights
@@Michallote well DRS is effectively active aero already
@@Michallote just had a refresher on the FW14B…not moveable wings, but the rear end sitting down on straights to stall the floor is an active aero of sorts. I understand now as an adult why ABS and traction control had to go, but why stuff like active and four wheel steering? This didn’t make driving any easier and we’re seriously cool tech. Also, why keep paddle shift boxes and not TC/ABS. Surely getting rid of H-pattern boxes was at least equal in making life easier for the driver…

I like your new look! Thanks for the great video
I love these kind of videos
Thank you for this explanation
Great videos...thanks a lot Sir...👍👍
I need this video for my thesis, thanks
Callum - great video. This aero ruleset sounds like the teams will need to maximise the side flow aero like Tony Southgate used on his Jaguar XJR-6 Group C car back in the mid 80s (all that free air pull into the diffuser ahead of the rear tyres) Keep the vids coming. Not long until testing and we'll see whether this FIA new dawn will be like all the others they've had over the decades that really didn't change much at about the running order.
This sounds like the hydrodynamic effect that draws boats (like the Ever Given) into the side walls of canals (say, the Suez) when they get a bit too close. The narrowing channel of water speeds up, creates a lower pressure zone, etc etc stuck boat.
Yup...."smelling the ground" and the bank suction effect 🙂🤝👍
We've been saying for a long time that all the cars look too similar. I'm worried they will now all look exactly the same. Definetly looking forward to seeing how they turn out and just hope some inovation has been allowed.
I was watching a video saying that some cars may even choose to forgo a front wing under certain race circumstances, like a low drag circuit like Monza. That would be nuts.
@@LOVEMUFFIN_official that would be a real sight to see providing that the regulations allow it. 1979-82 ground effect cars have a very iconic look due mainly to 1) their boxy shape caused by the aerofoils in each side pod, and 2) occasionally lacking front wings. I personally really like that look and to see a modern iteration would be very interesting indeed
@@LOVEMUFFIN_official This already happened in the first tunnel era. Look up cars from that time period. IndyCar really only use them as a balancing device on oval configurations as well.
I'm fine with the cars looking exactly the same, I just want tighter racing
@@FMXIAN go watch something else then like F3
I love all this stuff. I think an F1 paddock nerd would probably be my ideal job
Scarbs is the man! Been following him for years and years.
Animagraffs are awesome.
Cant wait for RB to come with some bullshit because they have man that sees air.
Newey the last airbender
I remember when i first saw driver61 and was stunned that he only had 60 or something thousand subribers. You could easily see that that number would increase fast and here we are now idk 15 months or so later i cant remember correctly (first watched video was the senna video pretty sure)... he is already at 750k. Great job scott keep making the team and the channel bigger and bigger good luck brother

It never ends so good as they want to.
0:23 We should add a real 'sprint race' sorta like old times Le Mans where drivers ran to their cars to decide their starting positions. Show certain detractos that race car drivers are real athletes and have excellent physical conditions ;)
Bernoulli principle is the basis of ground effects. Energy can neither be created of destroyed. The area under a car is shaped to form a nozzle forcing air to accelerate through the smaller area. The faster air increases kinetic energy which must take away from pressure energy creating low pressure
Whether it's Scott or Callum; the content is still superb
That looks like an old Reynard champ car floor. Hopefully they race as well!
Great video and explanation on how it supposed to all work. First race of the season will tell the tale if all this "therory" works as expected. I think we are going to have a great 22 season. We will see.

Best explanation of how these new cars are gonna make downforce I’ve found yet!!!
Holy crap. Dive bombs are gonna be nutts
This si going to be such a massive shakeup in driving style. I haven't seen anything like this since the first proper turbo era.
0:09 that image will never stop being iconic, will it?
CRAIG SCARBOROUGH....😀😀 WHAT A LEGEND OF ENGINEERING BRO!!!!!😀
With wing downforce replaced by more efficient ground effect, and then most of the complex barge boards banned...where is the air drag to come from? I suspect these new cars will be hugely faster in a straight line. Faster without DRS than 2021 with DRS? I think so. Baku, Mexico and Monza could be wild. I'd intuitively expect cars to accelerate quicker and longer, reaching a higher terminal velocity later on the straight, or having to brake before acceleration is over.
So I have a question, how effective will tuning the front and rear wings be (for balance of the car) compared to the 2021 cars? I imagine significantly less since most downforce is not generated by the wings anymore, right? Sorry if this is dumb lol
this guy has some huge pupils lol! good video
8:49 the
best part. mclaren chasing haas :D
Imagine there is contact and a piece of the floor (skirts) is broken. That's pretty much a retirement I assume, since the air being squeezed will escape and the downforce lost. Also it could create an unbalance in contrast with the downforce being generated by the otherside tunnel.
Hear me out. What about quick swap tunnels like FW. Genius idea , F1 call me for patent. LOL This is way to go. 🤭
But losing a bargeboard nowadays is also fatal
@@alesksander Believe in JESUS today, confess and repent of your sins. No one goes to heaven for doing good but by believing in JESUS who died for our sins. GOD loves you soo much unconditionally.🤩❤😍🤗
I believe he does mention this in the video.
Bruh, the front wing endplates used to seal the floor with vortices. Those are much more vulnerable (and they still had the bargeboard of course)
I guess blown exhaust might do a comeback
Bro yall have to get Scarbs a good mic. He def needs it
i see lots of f1 taking off soon
Going to be more like ‘let’s go karting!’
This remembers me of F-Tube, eventually something similar could show up this season
this vid needs ALOT more drawings to explain whats actually said and the effect of it
Bernoulli's principle isn't that complicated unless my understanding is wrong. A moving fluid (like air) has a certain amount of energy that is split between the pressure of the fluid and the speed of the fluid. So this under floor system works by shifting the energy on the top of the car to pressure and the energy below the car to speed, which results in the air above pushing the car down. I feel like you guys explained it without calling it out lol.
I don’t even really care if the following distance gets better, as an engineer I’m just really excited to see what the teams have done with these radically different rules.
Does this effect the spray in wet conditions?
nice Halloween costume
For those wondering how the low pressure is created through accelerating air, it's actually pretty simple. It comes down to conservation of energy. Basically, if you imagine air flowing through a tube, if there is a bottleneck the air must speed up since the total volume of air flowing through the tube per second is constant. However, since the air is going faster, if it had the same pressure it would have greater kinetic energy (imagine a bullet of high speed air hitting you in the face). You cannot increase the kinetic energy of the air locally at the bottleneck since, again, it is moving together with the 'slower' moving air in the tube. This means that for the kinetic energy to remain 'level' with the rest of the air travelling slower, the pressure must drop.
You could oversimplify it this way: Energy = air velocity + air pressure. Since the energy is the same everywhere in the tube, if air velocity or air pressure increases, the other must decrease. This is achieved in the venturi tunnels by creating a bottleneck (big entrance at the front of the car, big exit at the diffuser).
Please french substitles !
Your Chanel is awesome !!!
The really important part is that as flow velocity increases pressure perpendicular to the flow is lowered.
Are you referring to static pressure?
I am curious to see how much different designs every manufacturer will have.
As a fellow Mechanical Engineer (with more than a passing interest in fluid dynamics) - that was awesome.
Question thou, as the underfloor downforce is generated by air velocity in those tunnels (a function of the square of velocity ?) surely any sudden lift in the car, such as riding a kerb, will cause a drop of underfloor air velocity and a loss of downforce ?? Interested.
@Zuurker U Very good analogy
If there's a car following very close to the car in front( right on the gearbox) wouldn't the following car actually block/disrupt the airflow from the diffuser of the car in front and as a result wouldn't the car in front have lesser downforce??
If this is true, formula 1 may have just shot itself in the foot! Overtaking will now be too easy!
@@Credi44 well even if this is true I’m all for it! Go overtaking
Edit: and these regs are basically to improve racing and more overtaking by getting rid of dirty air
Let's be honest. The time you can completely block the opponent diffuser, you literally already crash into them.
@@bocahdongo7769 you don't have to block the diffuser completely, just a disruption of 10 or 20% is more than enough to make the car in front skittish and completely unpredictable
@@davester5234 yes we all want to see closer racing but f1 is not for show like wwe, it's a serious sport. I hope I'm wrong though
if the best place to follow a car is going to be slightly to one side of it, they are going to have be really strict about cars weaving when in defending a position
I don't understand why at the kick line of the diffuser It's where down force Is created, can someone explain?
If the last season was insane, this one is gonna be complete chaos, with new drivers, cars and regulations. Its set up to be an amazing season, fingers crossed, it actually is haha.
So this is similar to what ChampCars were doing 20+ years ago, right? I seem to remember one of the magazines back then, maybe F1 Racing or Racecar Engineering, explained how the racecars in CART/ChampCar could folllow more closely compared to F1 back then and proposing that F1 do something similar.
It precisely is.
Wonder if the drivers will stay off the kerbs/curbs now?
I think that is the first rule change I am eager about.
You should make a colab with some physics channel to explain the science. There are tons of fun channels that are great at explaining physics.
If you cant explain all here. Make a video please.
It seems from this video the teams all will have to have like the same Front and Rear Wing along with Floor. Seems these specific parts have a lot to do with how they want the dirty air to come off the car.
So, then my question is, Exactly what are teams able to modify on the car for aerodynamics?
And what could we expect some of these mods to look like?
I wish this video was more visual, I personally find it tricky to take in so much complex info with only audio
Technical Director at Haas: WRITE THAT DOWN, WRITE THAT DOWN!
That's like fining a colorful, round, metal cookie box only to open it an find your granny's sewing kit inside it.
I wonder how affected these 2022 cars can get by the debris on track. Probably it would turn into an irreversible issue as changing aero underfloor may not be possible. It could be indeed very dangerous, it would be like losing the rear wing on a straight. It is crazy to think that we may have multiple instances of issues like that
As a physicist I must say:
There's 3 phenomena that create lift/downforce in different measures for different occasions
-1st is Newton's third law, you push the air it pushes you
-2nd is difference in pressure
-3rd is coanda effect (the air sticking to the body), in airplanes the air travels from above the wing to underneath and that causes lift by newton's 3rd law but in a different methodology hehe
I wonder how a very uneven/bumpy track-surface ( like Monaco for example ) will effect this form of downforce.
But the challenge is, when the downforce comes from the top it is easier to adjust for high downforce or lower downforce depending on the track, but how it would work with the new car?
Scott looks weird today. Lol. I'm stoked this channel is growing!
Hey, Bernoulli's principal is easy, it's not that hard to explain if you explain it using the pipe example
Look at a low angle low head laminar flow dam. It's the same thing but upside down
Will there still be sparks?
Yes.. There will be sparks...
The wooden boards will probably stay
Perhaps just a small tip for the editor.
When switching between people talking, leave a small 1 or 2 second gap because at the moment they change speaking instantly, and it sounds like they are cutting each other off.
There are racing motorcycles, snowmobiles, boats and planes!
pressure does not drop because the air speeds up, the air speeds up because the pressure decrease. variation in air pressure cause wind.
i can't recoganise you without the beard
A couple of questions
1) How does down force from the diffusers vary with car's velocity? (linearly, or some other relationship)
2) Where will the centre of downforce be for these cars? (i.e will it be close to the centre of gravity?)
3) Will that vary with car velocity? (if downforce isn't linear to car velocity, does the C of Downforce move with speed?)
1. Bernoulie's priciple high velocity = low pressure
Low velocity = high pressure by expanding the air as much as possible by the diffuser, you'll reduce velocity and increase pressure of the air coming out the diffuser but increase velocity through the undefloor which descreases pressure and therefore a better suction effect to the floor.
2. To be fair I dont know I guess we have to wait and see what teams do but probs gonna be underneath the car between the driver and engine
3. Yes because going back to bernoulie's priciple, if you can get the air to travel at a higher velocity under the car you will have a more powerful suction effect to the ground which will increase downforce created.
For 3. If you mean will the centre of downforce change with velocity than most likely not but if you're asking if velocity can vary downforce then yes it will
Thanks for your explainations@@goaway3350they do help, but I should have expressed my questions more clearly.
1) I'm wondering if there is a linear relationship between car velocity and downforce, or if its a non-linear relationship ?
2) & 3) I'm thinking ideally the designers would want the centre of downforce acting in a position that applies the optimum balance of aero load on front and rear axles, and is consistent at all car speeds. This would make the car behaviour stable and predictable.
I'm wondering if the position, size and shape of the venturi's is fixed by the regulations, or if the Teams have flexibility to adjust these for their desired 'optimum' centre of downforce. (and the does it change part was a thought that if the downforce isn't a linear relationship with car velocity, the centre of downforce is likely to move with car velocity too).
@@JakobusVdL no worries, I tried my best to answer your questions again once you elaborated on them when you replied to me but I realised I made a mistake in that post so I will delete that post and rewrite my second reply to your questions.
So for 1. Pressure and velocity are indirectly proportional but not linear however increasing velocity will always decrease pressure. Just at a certain point the downforce would see a significant increase but after that significant increase its only small increases in downforce. If you look at a indirect proportion graph and just imagine x axis is velocity and y axis is pressure then you will see there is a significant dip down but after that significant dip it still decrease but at a less significant rate.
And for 2&3 I'm not sure how a non linear relationship would change the centre of downforce, scince the area where the downforce is created is fixed itself. best example is
50mph = some downforce
100mph = significant increase in downforce
150mph = increase in downforce but not as a significant jump as before from 50mph to 150mph just small increases which in F1 is vital. (The example can also help explain 1.)
Will there be DRS with the new Wang?
Yes.
Yes
