F1 Aerodynamics - 2: Turbulence, Drag and Vortices 

A lot of people are enjoying the outro songs to these videos. They're made by Banjo Guy Ollie - he does lots more of them over at his channel: ru-vid.com

We're doing science and we are still alive!

I start your videos thinking "well I probably know about that" and come out thinking "gosh, I knew nothing". Superb series, please keep them coming!

Never seen anyone explain aerodynamics in this depth before on RU-vid, never mind in such a succinct and well-presented manner. Keep it coming!

Can’t wait to learn about the aerodynamics of the underbody and diffuser!

you don't have to end this series, a lot of people really like this. It doesn't have to be a daily upload, it can be a once per month, or a do it whenever you want to series.

i didn't know aerodynamics can be explained so easily. wonderful

Wow. You are putting my personal knowledge of the sport of over 18 years to shame. Massive thanks for simplifying complicated details. There's always a lot to learn!

Such an amazing channel. The videos are absolutely incredible. Well explained and logical so inexperienced fans can easily understand the technical side of F1. The regulations are also very important and not well explained, therefore youtube videos are very useful. Good job!

Simply explained but highly informative, great job.

Awesome explaining! Simple enough to act as an aero primer, but still covering lots of more complex issues. I Learnded Things.

Amazingly done. I love your simple but beautiful graphics and your easy to understand approach. Keep it up!!

I absolutely love this whole series! I think its amazing how you manage to explain such a complex topic in a way, that everybody can understand the basics. Keep it up, your vids are great!

Your video's are so informative! :D Whenever I get a notification of a new video I immediatly go watch it. I know it's gonna be good! I follow F1 for about 2,5 year now, and I've always thought that the front wing was only there to push the nose down for extra grip for the front tires and that it had no other use :O

Finally someone who understands how a wing works. E: This is one of the best explainations of airflow around an object I've seen on youtube. BTW: All the motion here is relative. The air is *actually* stationary. :D

Once again, great video on aerodynamics keeping the concepts simple but expanding on the ideas from the previous video

Best f1 channel out there. Great job !

Superb, I think this is the best yet. Thankyou so much, I understand now for the first time why the front wings are so intricate! The animation at 5:21-5:25 is the key!

My god, at long last a video that finally has managed to clearly visualise the aerodynamic subject matter of what I'd only understood from a rough concept. Those animated displays of airflow behavior around the various vortex-generators and other parts of the car finally helped me understand and visually see how stall causes excess drag and how a vortex works to reduce it. THanks a million mate! :)

i like the new change in the background. It looks much neater and more professional! Keep up the good work!

My obsessing over the hull boards for my 4-8 km/h boat have brought me to your series, and it's very insightful; my boat will have great mileage.

So great, I've always wondered what was the point of vortices and why they were needed. It was explained so well here, this is my favourite video of yours so far!

As someone who had a vague idea of how aerodynamics work on an F1, this series has already helped me understand more about how smaller elements effect airflow, looking forward to part 3 :D

Amazing, man! Finally came to better understand a previous explanation about how lift is generated, that previous being made as a correction to a misconception about the Bernoulli's principle on the generation of lift, since it is free flow and not a restricted flow. In that one explanation they also explained that the lower pressure was not doe to the Bernoulli's principle, but yes that difference in pressures resultant of the shape, but, I wasn't properly understanding still how the lower pressure was being generated until now, with your explanation, now it's finally water clear. The vacuum, which would be generated otherwise, is the reason for the increase of speed and pressure reduction... Couldn't be more thankful, right now. Thank you!

Thank you. I'm doing a schoolwork about F1 aerodynamics and this video helped me so much to understand vortex

I hope you're making some money off of all these vids. They're so great and informative, this is what RU-vid has been designed for and this is the content that should be highly promoted. No clickbait, no drama, no bullshit. Keep em coming man, love it

You are legit the best informative F1 Channel ever. Keep it up man.

Literally the best thing ever.. This presentation is tops everything..

The portal music at the end👌 great touch

This is a fluid dynamics class :) thank you

Now i have a different view on F1 chassis thx

Thank you for clarifying at 1:37 that it is not drawn to scale! Fantastic videos: What a great way to teach physics.

Did you just... No way... You used still alive from portal as your outro song! HELL YEAH! I FREAKING LOVE PORTAL!!!!

Still Alive sounds really nice as an outro to your videos. Keep it for all your upcoming videos!

I love this series, thank you so much! Throughout the last year or so, I've become more and more interested in the technical side of F1, be it engine technology, aerodynamics, tyres etc. - and you've mastered the art of making a lot of the complexity somewhat easy to understand. Your channel is amazing, without a doubt my favourite F1-related channel. Keep up the awesome work!

ty for the correction at 1:12 i was watched part 1 3-4 times trying to figure out how the air flow will "Pull down" on the car, great video!

Wow! I never even had an understanding of drag in terms of pressure difference at both ends. I used to think it was only just air running into an object. Good work mate.

I recently bought F1 and didn't know why. But ever since I've found your videos, I've slowly fallen in love with the sport and now this is one of my favorite games. Thank you for all the cool information and introductory to a new sport

I learn a lot in this series. Thx a lot for making it!!!!

An absolutely great explanation. As a Mechanical Engineering student, this channel has helped me understand my subject much more. Awesome work.

Thanks for a fantastic video on aerodynamics - one of the best out there.

Thank you so much; this video was the best at explaining aerodynamics out of all the ones I've seen so far; great explanation!

You have some of the best F1 content in RU-vid not just recapping the lap times or gossip like everyone else - this is content creation!!

My wife was listening to this video in the background and was adamant that you were Brian Cox! Great video by the way.

Hi! Thank you so so much for these videos! I’m a mechanical eng student just fresh out of year 1, currently just trying to understand how aerodynamics is applied to F1 cars ( I only previously knew about aircraft ) and the videos are so crystal clear and amazing. I love how you enable the viewer to visualize the concept which is how I understand most things in physics, so thank you so so much. Really really appreciate this! It’s literally nat geo graphic air crash investigation level explanations ( even better) ! I love it!

Well, I was going to comment on how good this video was. Then I heard some obscure Portal music at the end. Whether you intended it or not sir, you just made a good video into a great one. Thanks.

This is so cool, thanks for another educational video!

Thanks. This was very helpfull in finally understanding why teams want all these vorteces along the bodywork!

I'm a maths students and I love Continuum mechanics, but I often don't learn anything about what it means for real life applications. These videos are amazing and just what I needed, and are also good as I've just started reading Adrian Newey's book and often don't understand what different parts do. Thank you for making these videos and hope they keep coming!

I'm impressed with the outro music Love Portal series

Really increasing my enjoyment of F1, keep up the great work!

The portal song for the out to is perfect! Love this channel.

This is so well explained. Nevermind all the details and minutae needed to have a comprehensive understanding of these dynamics. In terms of just understanding the reasoning behind the choices the engineers have made in this case, this seems to satisfy it sufficiently, without requiring a houndred hours of science education.

Wow, I can't believe I was watching F1 for so many years without even understanding about the technology in depth, this explains so much why one car design is better and faster on some circuits and others are better and faster on other circuits, brilliantly put video, this should have been explained by FIA so as to gain interest in the sport. Thank you for all your time and effort. I wonder how you've got to know so much..?

Thank you for all of the work you do to educate us on these interesting topics! As a mechanical engineering student in my first year, your channel helps me remember how interesting the stuff I'm learning is, and how it's applied, instead of getting caught up in how boring the lectures of the prerequisite classes may seem.

Please keep this series going forever

it took 1 video to clarify all my doubts. thank you soo much bro

Wow! So good, very well explained. Keep up the great work!!

that still alive outro is a really nice touch. matches the vibe perfectly.

OMG! This is the best explanation of how a wing works I have seen IN MY LIFE! Thank you!

I greatly appreciate the effort you're putting into this videos in order to bring such complex matter to the masses. I think that there are not many videos out there that can visualize some of the phenomena so intuitively. However, I think that some explanations, albeit in terms of simple newtonian mechanics phenomenologically not incorrect, lack some correct physical foundation. You describe flow separation as an effect of air particles not being able to follow the path curvature of the airfoil with the force of the movement being generated by a pressure gradient. In fact, travelling down the chord of the airfoil an ever increasing pressure can be measured (which ultimately will force air particles to flow backwards, forming a large region of recirculation, i.e. a vortex), so in stationary conditions the opposite observation can be made. This adverse (i.e. increasing in direction of the flow) pressure gradient can be explained with the decrease in fluid velocity due to the Kutta-condition at the trailing edge (i.e. the continuity of fluid velocities from either sides of the airfoil) and the therewith increase in static pressure (Bernoulli equation for barotropic fluids). Secondly, the fluid velocity within the boundary layer additionally decreases due to dissipation via friction which ultimately supports the change in flow direction. Also, you mentioned in the first video that the airflow below the airfoil is being accelerated because it runs into a barrier of undisturbed flow below and hence has to accelerate through a tighter vertical space. However, looking at a rectangular-shaped control volume around an airfoil and applying the Navier-Stokes-equations in integral form yields that there can in fact be momentum carried out of the control volume. This is because the vertical component of the fluid velocity can generally not be assumed to be zero (which can be proven by the displacement effect of boundary layers). If your explanation of the generation of lift forces would be correct, you would be able to measure a net downward force on the airfoil with the flow being inviscid, which has been historically proven to not be the case. Rather the phenomenon of lift is explained through viscous effects, namely the generation of a starting vortex at the trailing edge of the airfoil and another counter-rotationg stationary vortex around the airfoil, causing a net circulation and therefore a downward force (described by the Kutta-Joukowski-Theorem). All of that is described really well in Anderson "Fundamentals of Aerodynamics". TL;DR: I think for the vast majority of people, these videos are a huge help in understanding aerodynamics and the explanations probably are "right enough". But still I think that there are some things that are not entirely true from a continuum mechanics perspective.

Few of the very informative video I found about drag and vortices. Great work!

I really love the videos on aerodynamics. Being a huge fan of F1 aerodynamics, I hope you guys to continue the good work and get deeper into the concepts and and explain the working of all the aero devices used (including the banned ones). This will help us get a deeper understanding of aerodynamics applied in F1. Thanks a lot.

Wow! I have a new respect for aero engineers. It's almost a completely imaginary science, to anticipate how those invisible air molecules will move around each and very nook and cranny of the car. Legends!

THIS WAS A TRIUMPH

The Explaination was just brilliant. Cheers mate.

Just have to love this sport. Aerodynamics is more beautiful than any piece of art

That's a great easter egg at the end using Portal's theme!

Your videos are cool. They provide bite-sized information easy to understand.

Amazing video, as always!

This is fascinating! I didn’t know how they used vortices. Your videos are the highlight of my boring days! Thank you so much!

These interactive visual representations are wonderful! Thank you!

Really good job explaining the basics and principles of aerodynamics in this "easy for all" way. Thanks, man!

Love the series, amazing video

I feel like Chain Bear is about to take off in his RU-vid career moreso than he already is

Wow, amazing video! The background is more eye-soothing as well.

What I was waiting for! The effort in these videos is just amazing. Keep it up! :)

Very good video! If anybody want to see an actual vortex, google "vortex y250". It's the name of the vortex mentioned at 6:18, and the most important one on the car. When I learnt about them I thought why are they useful. I got no answer yet but, if you think of them as tiny horizontal tornadoes (that's what they actually are), you can imagine the level of pressure and suction they can produce around them and how, by controling them, aerodynamist can make the car stick to the ground how they want it to. So they are really interesting and useful

F1 aerodynamics is so interesting! I have taken fluid dynamics and done some CFD on aircraft wings but these kinds of vortexes and that forward wing look like they have taken decades of wind tunnel work to perfect! Incredible aerodynamics and explanations in your video!

Great video. These are the kind of things I've never thought about despite watching F1 since being a little kid, but now that I hear about it it's actually super interesting.

This made a lot of sense for a typical layman. Thanks!

Great video ! Lot of details explained on very uncomplicated way! Love it 😊

Mate your job is sensational

Your videos just keep getting better! I really appreciate them.

This was so interesting that i didn't even realized that 7 minutes had passed. Thanks for this nice quality serie

Seriously I was just thinking how Ted’s notebook development corner has got nothing on you! Great stuff!!

Great presentation. Nicely explained

How fucking smart are those engineers!? Great video as always mate

Nice job

I learnt more about aerodynamics here than I have at uni. What a good video!

Very informative video Never knew that a vortex can aid in the increase in the downforce

this helped me SO MUCH with my school project

I learned sooo much in this series its great!

I'm now clear with all the concepts... Thank you

I am so thankful for your video. Thank you so very much. I want to build a truck that looks fast going still using aerodynamics. I don’t need the aerodynamics to actually work to principles, just to look smart.

I always smile a little when I hear the Outro-Song "Still alive".. ahh.. so many memeories.. :D Good job on this video by the way. Really enjoyed it!

great video, keep on moving sir keep on moving :P

I actually already know all this having self studied aerodynamics a couple of years ago. (Goro Tamai is a really good source ^^) but I seriously enjoy you unwrapping layer upon layer 😃

Well done! Cant wait for more!

These videos are awesome 👏 keep it up!
