@nicolasperalta3052
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.

@jemoeder841
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?

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

And/or subtitles? Just like ted.com (google subtitles DEFINITELY does NOT help).
Thanks again!

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.

What if this is peacocking? Or whatever the equivalent directed at other males is called.

@thierrantavakoli9264
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?

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


@jameswright4732
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).

@muckyvagrant3632
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 : @ericsbuds


@ThZuao
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.

@xuanyulyu52
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. ;)

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.
