F1 airflow explained - part 2

[@OnkarPankanti_jr]

that man was so happy to see those things animated..

[@videostar75]

Back in his day, there were no animations

[@TheMenendezzzzzz]

he is like that in real life, such a great guy

[@g_pasture1347]

Hmm I am just wondering if he is an aerodynamicist, he should have seen those simulations as these were largely done through CFD software. Or perhaps it was just his enthusiasm haha (:

[@cpf6125]

Infectious enthusiasm.

[@sultanabran1]

Get Willem to do a 2 hour video on the whole car please! I'd watch it over and over .

[@henrih3080]

Yes we need a really long video !

[@TA351]

The enthusiasm and knowledge this guy shows is awesome, then add in his reactions to the animations. Great video.

[@thepaisleyproject]

As an aerospace engineering student I find this stuff SUPER fascinating. I think it may help with my aerodynamics sections

[@flamespirit919]

I'm in the exact same boat. Looking forward to my fluid dynamics and aerodynamics classes.

[@thepaisleyproject]

F1 as a sport leads to so much innovation, I love watching what the teams come up with to get that small competitive edge over the other teams.

[@flamespirit919]

I also love to see how F1 innovations are translated to aircraft and vice versa.

[@angelosoede]

what is your study like because i heard you need to be outstanding at maths and that scares me off a little

[@thepaisleyproject]

Angelo Soede i havent had much of an issue with the aerospace classes, but there is a lot of math involved. The actual math corses arent easy though

[@ebola1974]

Finally, someone has done what I've always wanted! This is something SkySports F1 should have been doing from the beginning. It's all good to say 'McLaren have a new front wing with x amount of new vanes', but I've always wanted to know why and how has this improved the car. Please delve deeper into the power units, gearbox and floors of these cars :)

[@asherrose4114]

iv always wanted to see how efficient the aero was on 90's, 80,s and especially 70's f1 cars

[@larrybethune3909]

Well said Mike. Sky seems to not be forward focused on raising the standard and quality of the information they disseminate. Where's Ted's weekly show for example? I suspect this is a consequence of the near monopoly they have for broadcast rights. Thanks Scarbs et al.

[@wasuprobleemjoh]

im so curious about the effect off aerodynamics, i dream to have a little homemade windtunnel and buy some scaled race cars from all era's to look how they behave against the air!

[@asherrose4114]

or maybe sky can do this for us :) :) :) :)

[@sultanabran1]

Sky can't do this when they spend 90% of their coverage talking about Hamilton. and who gives a shit what Ted has to say, it's always rubbish. he's a clown.

[@kennyschachat]

Excellent video! I've been looking for a detailed and animated video that demonstrated modern F1 aero for along time. Please continue through the whole car.

[@almarma]

0:07 Look at that! I was feeling the same! Awesome video finally showing how the vortex look and work together!

[@petertimowreef9085]

Aaaah so that's why everybody keeps adding elements to their cascade! More elements means more mini vortices means a stronger Y-250 vortex means more air is pushed out the sides of the car to make the low pressure area under the car stronger. These two videos were very enlightening, I feel smart now.

[@georgejin1764]

After 3 years this is still objectively one of the most FASCINATING videos ive seen in F1. more of this please!

[@AlexHung]

So good! Now can we have another one like this but for the central/under nose part of the flow?

[@jamalthasim9041]

Alex Hung yh i really want to know all that happens underneath like with the s duct

[@Whopcap]

YEs please!!

[@mubbasherniaz8082]

You can just feel the guys excitement for his job, amazing passion

[@guitarsword1]

Absolutely fantastic fluid dynam presentation and the best men to present it. Tnx Scars and William Toet. William got so excited.

[@sudijad]

Great to see a video discussing the (detailed) technical aspects of the sport. By reading the comments section you can tell the intellectual difference between viewers of this video and other F1 videos. This video is about fact and other F1 videos may come down to opinion.

[@TheGU1T4RFR3AK]

can you do more of these? this is great stuff. as a fan, this is exciting stuff!

[@Abdalla-E-Mohamed]

Please continue doing these, working the aero all the way to the back of the car

[@kewinczarny5985]

Thank you guys! Finally I understand how rotating direction of vorteces are determined.

[@Whopcap]

This video is so good and informative. Even though I'm not the most clever person in this area, just watching it a couple times makes it much more understandable WHY the build the front wings in certain ways. Thank You!

[@casualobserver1204]

Love his guys passion!

[@krash4291]

Hoping to see more!

[@girish3073]

Mr. Craig and Mr. William , Thank you !!!

[@samirsadixov]

PLEASE DO MORE OF THESE... Brilliant video!

[@enterthebully9968]

Loved this. Loved the guests enthusiasm too

[@GiggityyyGooo]

Willem please come back sir!!

[@agoogleuser3804]

Excellent video and superb narrating by Willem

[@alexk.8715]

Super awesome explanation. Would love to see more of this.

[@theslimeylimey]

Excellent presentation thanks! Very nicely animated. It would be nice if he had a pointer or touch screen to point out the specific parts he is talking about just to make it even easier to follow.

[@sallembajrami3868]

Thank you so much. Highly appreciated.

[@whaazup4ma]

i think there's a mistake (?) with the animation. when its moving at 0:31, it shows that some of outer parts of the wing generate clockwise vortex, but when its static, at 0:51 the same arrows show opposite direction

[@cpf6125]

Well spotted - you're right.

[@hamidamini7528]

Please make more of these type of videos.

[@FakeItalianoII]

Excellent video, excellent explanations !! Thank you !!! :)

[@andrewandlm]

This is BRILLIANT! !!!

[@SufferingAddict88]

amazing stuff! thank you for the great work!

[@JonathanAlex27]

I want this for every single part of these cars! :D

[@douglasalan5783]

Fascinating. The wings from the late '60s, '70s, and even the '80s seem so crude by comparison.

[@carls-95]

These vids are so cool! Would be cool to see a comparison of a 20year old car compared to today cor example

[@Joe-nf5wk]

This is amazing, thank you!

[@JoeyTeson]

Cool to see Supercars on in the background

[@videostar75]

Really great, but a few things are taken for granted and I'd love to see them cleared up. Why does the front tyre wake drift back towards the car? Why doesn't the Z250 vortex drift back towards the car? How exactly does the Z250 vortex 'block' the tyre wake and keep it outboard?

[@Sum_Ting_Wong]

Seriously good video!

[@tadhg1959]

I love these ...fascinating science!

[@king_cnut]

This is excellent!

[@kmnevergivin_in2326]

More please!

[@azharulkamil7551]

Make more kind of this vid

[@sserembaddrakell2181]

An F! Super fan here in Ug. Oh yes,loving this.

[@akwenda3678]

It's the passion that's kept me watching...Not mine

[@Charles-fc9gi]

Can anyone explain why a vortex is optimal and not a normal flow of air? I might have missed it in te video, but i didn't see it, so if you know where they say it tell me, thanks.

[@randompalmtopgaming7541]

Charlie Met het poepie well, my understanding is that a vortex is easier to direct towards the underside and hence the diffuser which is by far the most significant downforce generator (makes about 60% of downforce while adding almost no drag)

[@RallyDriva]

Charlie Met het poepie I think it only applies in certain uses. The vortexes coming from the front wing can be used to effectively seal off the underside of the car, stopping air from getting underneath, and therefore increasing it's efficiency. But on a wing, I'd imagine that a straight flow is best.

[@wiryantirta]

meanwhile at Mclaren... "so I gave this intern access to our dropbox folder and guess where the aero simulation video ended up the next day!"

[@DylanNicely]

love it great content

[@dannyr2976]

That's on man who loves his job!

[@stephencalvert6040]

And I thought the idea was to smooth the airflow............. Thats why cars dont like dirty air right?. And I thought I had a handle on it. Oh well, back to school.

[@JettXxB]

Well you don't want to be in the dirty air but you want to have dirty air A) because more down force usually makes more dirty air B) it will slow people down behind you making it harder to pass. That is why they have to change regulations to get cleaner air, because no team would make a slippery car if they were allowed to make one that isn't.

[@matteusmaximus]

@@JettXxB Closer but still not quite there. Downforce doesn't necessarily produce dirty air (as will be demonstrated by ground effects in 2021). Outwash/vortexes create dirty air. Also, cars do and don't like dirty air.... Dirty air does NOT slow the people down behind you. Dirty air is what creates the slipstream behind cars, which allows for trailing cars to close distance on straights. The problem is this same slipstream also massively reduces the downforce generated by the trailing car (as the aero features are designed to operate optimally in normal or 'clean' airflow) which severely hampers the cornering speed of the trailing car. And as F1 cars are predominantly reliant on downforce/cornering speeds for their record setting lap times, the speed gained from drafting other cars (due to dirty air) is far overshadowed by the time lost in cornering speeds (due to the same dirty air.)

[@johng94x]

Fantastic!

[@tomasjmr]

keep this coming :D

[@aidanmargarson8910]

Ive been thinking about the layered elements at the front of the wing. Could you incorporate that principle into a MotoGP fairing in order to improve the downforce/anti-wheelie aspect?

[@afoxwithahat7846]

Yes

[@maxbenard2246]

Great video but you didn't at any point say what the endplate vortex is for. Is it just working with the Y250 to tunnel the tyre wake, or is it doing something else?

[@marcusteske1951]

Max Benard That is the impression I got from the animation. I would suppose just based off this video that it would be important to funnel the dirty air from the tire wake and keep it from slipping under the car and creating positive pressure or to keep it from unbalancing the rear wheel (think Red Bull's old blown diffuser trick). However, not every end plate has been super critical to the performance of the car as Ferrari proved a couple years ago when Vettel damaged his front end plate in a race and afterwards admitted he had no idea had happened. I took to mean he felt no significant change in the balance of the car.

[@maxbenard2246]

+Marcus Teske That is an interesting point Marcus. Seems the endplate isn't really that important which corresponds with what we are seeing in the animation as the y250 has already done most of the funneling. But I guess I would still like to know why the endplate's vortex is necessary at all given that it doesn't actually separate the car and the tyre wake. In some ways it almost looks like its preventing the tyre wake from leaving the car!

[@therealrh]

So.. when is part 3 ?

[@Cullbar]

this is fn brilliant

[@christoffergrinsted]

brilliant

[@jonarruda2719]

I love this

[@asherrose4114]

they should show this during the race build up instead interview pointless celebrity guests on the grid....................................................................... like jolyon palmer SHOTS FIRED!

[@Sum_Ting_Wong]

Now the FIA has to standardise the front wing and the teams save £10m a year on RD.

[@deriktofil]

I'm really stoned but that guy knows his shit!

[@niteshmurti]

are the front wing angles adjustable like they used to be earlier?

[@joostin123]

niteshmurti think they can adjust certain aspects of AoA on the fly during pitstops/garage time, can usually see it during practice or qualy :)

[@theempires5]

Justin McDermott I think that in 2009 the driver can adjust the flap of the front wing (up to 6 degree) when following other cars so that the following car will not lose downforce. Never know that such practices is being used today...

[@joostin123]

theempires5 oh I just meant the crew perform these changes

[@afoxwithahat7846]

Subtitles are required

[@Ratelau]

These extremely complicated front ends are part of what is ruining F1. Not only do they cost 10s of millions of Euros to develop, they also make it much harder for cars to follow each other and give the drivers an opportunity to overtake.

[@ishaansingh7934]

I have a question, when we consider wind tunnel testing, doesn't the air that is being blown over the car in a wind tunnel give a different effect (because it is moving), to the stationary air that the car is driving through? So then how accurate is wind tunnel testing really?

[@costinioana]

The air IS moving relative to the car in a race. If the wind blows with 20kmph OR you put your head out the window of a moving car which goes 20kmph, you feel the same air movement.

[@asherrose4114]

i always thought this as well,

[@openbabel]

so what happens in a corner ?

[@sujayf1158]

cool!!!!

[@TheDeathJesters1337]

But the McLaren never goes fast enough to use aero....

[@timkis64]

then they wonder why F1 is so expensive, & make limits to curb spending.its their own dumb fault.

[@inkjazz]

Mmmhmm.... yeahhh... mmhmm... yep...

[@zooski1516]

Again those damn noises coming out of your mouth. Just listen and stop with the uhHuh. Arggg. Where do they find these people

[@Whopcap]

This video is so good and informative. Even though I'm not the most clever person in this area, just watching it a couple times makes it much more understandable WHY the build the front wings in certain ways. Thank You!
