Ok now talk the weird tube structures Комментарий от : @TheAlison1456 |
Thank you for the explanation my friend, but there is some mistake in your lecture. The turbulent flow is not necessarily undesirable, a turbulent flow near to the wall can delay or even suppress the flow separation, that’s why some wings has vortex generators.

Could you use flow viz on a road car? Комментарий от : @bobwalsh3751 |
McLaren uses it a lot, and I've been wondering why are they spraying that paint typa thing. Thanks Комментарий от : @namanchauhan245 |
Cfd stands for computational fluid dynamics, not computational flow dynamics Комментарий от : @professionalprocrastinator8103 |
imo flow viz paint, if used sparingly, look really good. Комментарий от : @shyasaturtle |
Williams engineers: "what's wrong?" Williams mechanics: dumps multiple buckets of flow viz Комментарий от : @patrickracer43 |
its Bad when 1 driver likes the wing and other doesnt then the team makes the slowest possible combination for quqllyfying and race WTF Комментарий от : @davidmiranski5237 |
i love aerodynamics / stop FUCKING IT UP / read up a bit on aero and then dont do a vid on f1 Please .. Комментарий от : @davidmiranski5237 |
If dan went to redbull Double torpedo Комментарий от : @harrypoon3410 |
You said the smooth airflow (I assume laminair?) sticks better to the surface, but I thought turbulent air sticks better to surfaces with the downside it increase the drag. For example on airplane wings it is desired to have a turbulent flow, because is it increases the lift. Is there something I have been missing? Комментарий от : @jemoeder841 |
you legit could have just said "It does exatly what it sounds like" lol Комментарий от : @chaoszombie9995 |
Does anyone know where to buy it? Комментарий от : @AffirmingFoil7 |
Paraffin and kerosene are not the same, btw Комментарий от : @postmortemspasm |

mannn, that outro is nuts!!!! someone knowa the name or is it exclusive for the channel?? Комментарий от : @edullfranz |
It's actually not true that laminar flow sticks to surfaces all that well, in fact turbulent is the best at delaying flow separation. Комментарий от : @Bruno-cb5gk |
My realy first thoughts were that i didn't saw well... Why it has to be green in a McLaren... Afterwards, i saw your video... So, it was useful... Комментарий от : @vag.cho105 |
Did not knew about this! Thank you! Комментарий от : @84pontiacdreams |
Wait. Are you saying paraffin is the same thing as kerosene? Комментарий от : @admiralpercy |
To be fair, Williams was testing a 2019 spec front wing. It was probably more of a quick way of figuring out how viable their current design is for next year Комментарий от : @tetra2804 |
For a technical video about aerodynamics, I'm surprised the word "laminar" wasn't used Комментарий от : @winstonhale4674 |

Good job, now I want to try that on my touring car Комментарий от : @NicksStuff |
Williams team: "Aw man, how are we gonna test our aerodynamics?" employee comes back from the gay pride across the street Williams team: "That's it!" Комментарий от : @jackcurtis9002 |
Smooth flow into that sponsor :D Комментарий от : @EversonBernardes |
just a possible small correction you sugest that smooth air flow sticks to the body more however this isnt true sometimes turbulent air is induced because it sticks to the body more then smooth airflow Комментарий от : @eddiebooth9795 |
chain bear F1 thank you for the videos Комментарий от : @CommunistRSA |
I wonder how the new engines will sound with 3k rpm extra? Комментарий от : @TheHeavyshooter |
I would love to hear about super license and how you get one and what happens with points on the license. Комментарий от : @BigWhiteCondo |

Hi guys:-) Great video, appreciate & send you couple of bucks thru Patreon. BUT! Would you mind guys ... for us non-native speakers SPEAK MORE SLOWLY PLEASE. It is sometimes REALLY DIFFICULT to understand:-( And/or subtitles? Just like ted.com (google subtitles DEFINITELY does NOT help). Thanks again! Tk. Комментарий от : @tom2you |
In the olden days , they used wool tufting. Small strings o wool attached to the car. These would move with the airflow and give a good representation of where the flow was separating. Комментарий от : @WolfJustWolf |
What is ERS ? Комментарий от : @meap6739 |
Williams was testing the 2019 spec front wing on their car after the Hungary GP. They covered their entire package in flow viz because the new front wing will change the airflow everywhere along the car Комментарий от : @escaperoute2 |
What if this is peacocking? Or whatever the equivalent directed at other males is called. The teams are plopping this paint on their cars and getting these beautiful smooth lines, and the other teams are looking at those lines like "oh fuck look how good their car is".

Thanks for another great video. Комментарий от : @LordKirtash |
I just have a random question. If Williams' 2018 car is such a dog that it needs flow-viz paint for the entirety of the car, why not run the 2017 car for the rest of the season? Surely it give an equal chance of scoring some points or at the very least they'd still be in the same situation they are now. Is there a regulation against it? Комментарий от : @thierrantavakoli9264 |
Somehow, I feel like this channel explains physics better than Engineering Explained. Sorry EE. Комментарий от : @AlphaAce15 |
could you make a video on the technology behind onboard cams ? how they wipe the insects during the race, the regulation around it (are they compulsory ?), etc. I think it could be an interesting topic, i haven't found any info Комментарий от : @pilotofjet |
The main thing you're missing in your explanation is talking about boundary layers (which I don't blame you for as it's a but of a complex subject, especially if you try to explain why boundary layers matter). This kind of visualization is fantastic for determining where your boundary layers transition from laminar to turbulent. This transition is can be used for determining how "hard" you are working the air and how close the air is to detaching. This is especially important because A) CFD has a difficult time determining these transitions (there are models, but they have to be calibrated and need to have some baseline, which flow viz can be used for) and B) the transition on the 60% scale models isn't valid as the transition is a very scale dependent phenomenon (and Reynolds number scaling won't quite be accurate either).

Would be great to have some mid-season analysis of how Ferrari have now supposedly got a better package than Mercedes. I'm a fan of both Seb (great bloke) and Lewis (because patriotism) and the season is on a knife-edge. Where do the strengths lie? The man? The machine? With cars developing and evolving between races more than they did in a season when I first got into F1 it's bound to be hard to keep up but if Ferrari have an edge... what is it? Or even what do you think about it? Комментарий от : @muckyvagrant3632 |
Neat vid. Mark Priestly did a neat vid on this as well. Комментарий от : @slikrx |

interesting! I couldn't figure out what they were using it for, so thank you! Комментарий от : @ericsbuds |
You can also apply drops of it to better analyze flow at slower speeds. The tricky part about this paint is getting the viscosity just right for the speed you have to analize. Or maybe my mixes aren't quite right. The F1 high speeds make it not a problem, but I work with very slow speeds in competition RC planes, so too viscous and it doesn't flow while upseting the airflow itself (I use spots instead of lines. Will definitely try lines next time). Too flowy (too much kerosene, basicaly) and it dries too quickly. Also, it's the kerosene that evaporates. The parafin (I use literaly grounded candles. Am I doing something wrong? The kerosene should dilute it) is what helps the dye stick. Also(2), food colouring works for the dye. I tried using powdered chalk first. It sucked. The trails are too faint. Maybe because my entirely empirical mix is wrong but maybe because the chalk flakes are too big. Powdered colored candles do not give enough dye. Methylene blue (engineer's blue) is said to work the best, but I haven't tried it. With food dye, I have a myriad of colors to choose from. Oh, another problem that I can't replicate on CFD is Flutter (Yes, I'm very entry level when it comes to CFD. But I'm good with fluid mechanics and coming up with experiments). Basically when the wing structure is not rigid enough and jumps around like mad, especially when it combos torsion and flexion. It disrupts the airflow, often producing some turbulence, and can even stall the wingtips or even break the wing through fatigue. I haven't faced it yet, but it's most likely going to show when I start researching winglet designs. Комментарий от : @ThZuao |
do the aero industry use flow vis paint as well? seeing that many f1 aero's have a synergy with the aircraft industry... Комментарий от : @mrrolandlawrence |
Did Squarespace sponsor this video? 😂 JK Chainbear you the best. Комментарий от : @colter512 |
ah so that's what was on the Force India front wing.. I was wondering why the sudden change to green Комментарий от : @allenqueen |
Computational Fluid* Dynamics. Great video btw. Комментарий от : @ArtiQormemeti |
Flow-viz is a good and necessary tool for validating the on-body surface flow field, however not being able to reflect specific data is not its only disadvantage. Flow-viz merges the surface flow field under all circumstances, including straight line, turning (yaw, when the air blows the car at a changing angle while turning), braking and accelerating (the diffuser may have flow reattachment during braking but delibrate flow separation during high speeds) and roll. In technical terms, flow-viz reflects mainly a 'steady' state, but is unable to tell the 'instant state problems', happening only during a certain stage of the car's operation envelope, and that's why flow-viz can only be used as a crude method of aero correlation on track. In addition, the 'grilling grid' is used to measure off-body flows at every specific moment, especially tyre wakes and vortices, to further detect instant problems and the car's aero robustness. ;) Комментарий от : @xuanyulyu52 |
Is it possible I can make flow wiz paint at home? I saw that all i need is oil and dye but like what type of oil and what type of dye is needed? Комментарий от : @alekspaho3065 |
CFD = Computational Fluid Dynamics Комментарий от : @stephenwhiddett |
The qualifying in Hungary with the rain showed some really cool patterns of the water coming off the back of the cars in vortices. You could really see how high and wide the rear wing and airflow kicked out the dirty air behind the car. God’s flow viz Комментарий от : @aaronj84 |
CORRECTION CORNER: CFD = Computational Fluid Dynamics. I think I'd just been saying 'flow' so much my brain broke. Комментарий от : @chainbear |
F1 Science yeahh!! Комментарий от : @gerardotrejo7890 |
Odd question: Will there ever be any videos on other racing series? Sure, many of the concepts of overtaking, and clean/dirty air, and tires and brakes carry over very well, but I'm curious if you'll ever look into the rules, or technical aspects specific to IndyCar/Rally/NASCAR/Drag/WEC. I love the content you put out and would be interested in seeing your take on other styles of racing. Thanks. Комментарий от : @isaacstevens5415 |

0:16 CFD usually means Computational Fluid Dynamics, I am not sure; I might be wrong. maybe it's also referred to as Flow Dynamics. Комментарий от : @brod515 |

THANK GOD YOU DID THIS VIDEO Комментарий от : @HaloReachsquad6 |
Wow, this video was incredible Chain Bear. Thank you. I always love that you take complicated things about F1 & make them so digestible & easy to understand, but this was even more. It took one of those things I always just dismissed as F1 black magic & made it easy to understand. I can't believe I learned this much about interpreting Vlow Viz. That's incredible. Комментарий от : @elvisg7 |
Didn't think this topic was going to be very interesting but Chain Bear has done it again! Well done mate :) Комментарий от : @zzzonked666 |
Bravo another fantastic video! Fresh well delivered objective information, fans deserve access to. Liberty media should be sponsoring you. Ps do you think they should they bring back tyre manufacturer competition. Комментарий от : @cadelaide |
You know it's really bad at Williams when they were like "Ok, so what parts of car is giving us problems?" "All of it. Just...all of it. Put flow-viz paint everywhere" Комментарий от : @vectoredthrust5214 |
