I just found the best f1 channel. Man being a Mechanical engineer who excels in cfd i wanted to have this kind of video. I planned to make it on my own but due to hardware and time I couldn't. Hope you grow exponentially.
Great job on this video! I am glad someone with aerodynamic expertise has finally taken a look on this widespread rumor. Regarding your last bit about management of the pressure differential across the front and rear face of the tyre: is this one of the reasons why lateral expansion of the diffuser is favorized over vertical, because the front-facing side of the diffuser would act as a high-pressure side of the aerofoil increasing the pressure behind the tire and therefore lessening pressure drag? Would the same thing be the case for bargeboards (at least the first iterations of them) which would make them a drag reducing device as well as a wake management one? Also, I would highly appreciate if you would be able to make one of your videos about bargeboards even though the current rules forbid them. I assume that they have very complex flow fields given how they looked before the ban but general overview would be nice. Best of luck with your youtube career!
Thanks for this video. As always, your videos are extremely interesting and simple to understand. Let me ask you a question: is there any book that you would sugget a car enthusiast to read, in order to (try to) understand more about aerodynamics of F1 cars? Thanks again and keep working like this
Schub, great video, still beyond me, and I am looking forward to your intro to aerodynamics course. But what strikes most, how many different aerodynamics programs are in the market, or do each team develop their own? If each team develops its own, that to me says RBR knows more than its competition.
That's an official employee shirt (the one you're using) or can I buy something similar from RedBull? I would be interested in Vettel-era Shirts. Thanks in advance.
Please make a video on the Ferrari! I have a feeling once they tweak the rear suspension it will be alot more stable at the rear and better tyre wear. Maybe even with a Little slicker side pod design they'll gain a few kph overall.
Doesnt stalling an aerofoil also induce drag? Question about how the diffusion expansion affects rear tire drag. If diffuser expansion promotes flow attachment, doesnt flow attachment reduce the boundary layer effect at the rear of the tire and thus drag? As far as i understand, thats why vortex generators exist, to promote flow attachment which reduces the low pressure attached to surfaces. so in this case, wouldnt you want the flow to stay attached behind the tires to make it as similar to the front of tires, thus reducing drag?
The tyre drag is a bit complex . I see your point if you think of it just like a cylinder. For the front tyre , wake management is important coz that wake lands up onto the car. For the rear tyres , the wake has no consequence downstream. Also it's about which phenomena creates a more "low pressure" , remember in isolation , you would be right , but the rear tyre flowfield is highly affected by the diffuser and that governs the pressure field behind the tyre. The colors of CFD are just relative. 🙂 I asked myself the same q btw... 😂
Stalling an aerofoil does increase drag, but it's less lo the case with wings. If the rear wing stalls, the induced drag decreases massively, which is a huge favton on an F1 car. The pressure drag is also big in wings at high angle of attack, which is decreased when the wing stalls. Usually it's better to avoid stalling though, not only because of downforce, but because of drag also.
The current diffusers are set by regulation but it looks to be beneficial to run a narrower diffuser exit. This gets the air flow away from the wheel wake and as you show creates less drag. Would that work on a GT type car? Or would it be best to run the full width.
@@f1aerodynamicist on my own experiments I have found vortexes going into the tunnel rather than coming out and sealing the edge when the diffuser ends up wider at the exit.
@@alecrl1 that is definitely true and as it should be due to the low pressure inside the tunnel. But the name of the game is the reduce that effect as much as possible. You have other devices to help you such as the rear brake winglets etc.. and I do see your point also. let me think about that a little more. It would be great if u are open to share some of those results
@@f1aerodynamicist I have built a Ginetta G20 coupe with lots of aero mods this is to race in a 2 hour endurance championship. So now where near as advanced as What you do. I do have the ability and time to make changes to my car quite frequently and will be trying my new diffuser in a couple of weeks. The racing is streamed on TH-cam.
Parasitic drag is due to surface imperfections like body panel gaps, bolts rivets, rough paint etc. Parasitic drag always acts when the flow is attached and the surface isn't smooth. Induced drag, or pressure drag, is due to various parts like the rear view mirrors, vortex generators, the tires, halo etc.
I guess they can afford to bring slightly different spec cars to suit the track when they overspent on the budget cap. And only for a piddle piss 7 million fine. Ver first 2 titles are tainted, red bull are cheats but I also take my hate off to the genius they is Adrian newly, McLaren made a massive mistake letting him go over a wage dispute. The red bull car is a thing of beauty, just ashame ver doesn't have a team mate that can match or push him. When Hamilton won his titles his team mates were pushing all the way. Perez just doesn't have skills to drive that car, but red bull don't care because their golden boy is winning and getting the constructors points.

Thanks darshan
Really enjoying watching your videos, explaining the theory along with the visualizations. Keep the coming!
Thank you Carl 😊
Awesome insights, very enjoyable and learnt alot. Would love to see an sim/analysis of the floors.
I didn't understand about half of it, but I get the general idea. Thank you for making this video.

Great video series. I found you after your analysis on Peter’s site. I look forward to watching all of your videos. Kudos.
Thanks Neal
Would you try to do more analysis on the wake reduction of the tires. Lot of opportunities.
Really cool. Thanks for sharing.
Welcome 😁
Found you through Peter Windsor, thank God you're there!
Thanks mate.
Quite interesting and quite complex.
Thank you 😊

Mostly teams use the standard softwares but have their own models within it to improve their modelling
@@f1aerodynamicist My guess is RBR developed a really good package for their own use.
@@f1aerodynamicist can you list top 3 cfd softwares used in RBR,MERC
Great video ❤
That's an official employee shirt (the one you're using) or can I buy something similar from RedBull? I would be interested in Vettel-era Shirts. Thanks in advance.
I am wondering if the FIA will step in and place a keep out zone for 2024, where the current beam wing sits in a bid to peg back the Red Bull.
Well, they can only come in on safety grounds
Please make a video on the Ferrari! I have a feeling once they tweak the rear suspension it will be alot more stable at the rear and better tyre wear. Maybe even with a Little slicker side pod design they'll gain a few kph overall.
Coming soon , the Ferrari and the RB19

Ahh I'd disagree it's not that simplistic that area

A lifting body produces downwash, shouldn’t a downforce-generating flap produce upwash?
To me this would seem to show that all teams should be able to achieve this triple DRS easily if was as simple as some make it out.
It's not simple at all , as I said it's a transient phenomenon , and it's very very difficult to have the fidelity of tools to achieve this
the 2023 f1 cars work with upfors not down force rite ??
The fudge 🙃, it's all still downforce 😅
1 beam wing with drs on = better flow?
Nope , situational , but Definitely less draggy .
Redbull's rear wing has a "v" cut in the middle
Is pressure drag the same as parasitic drag?
Parasitic drag is due to surface imperfections like body panel gaps, bolts rivets, rough paint etc.
Parasitic drag always acts when the flow is attached and the surface isn't smooth.
Induced drag, or pressure drag, is due to various parts like the rear view mirrors, vortex generators, the tires, halo etc.
Land up land up, we are landing up on the moon everybody!
Soon enough mate , maybe even with some F1 cars 🙃, RedBull would be up for that stunt
Adrian Newey who?
The guy who designs everything 🤣
