@wave83X @piastried He went past at least 3 blue flag screens on track. The blue flag not showing on his steering wheel is not an excuse tbh

@jsolanesgarcia @Nachez98 None of the pit crew have pit stops as their only job. All of them are mechanics or else and have been trained/selected to also do pitstops. The same would happen to people selected to do refuelling. so no additional cost there. What infrastructure do you need for refuelling?

[Pjeki @Pjeki_]

@senjaalen @jsolanesgarcia @Nachez98 Depends. Yes, in theory, they will be lighter on average so will be able to use less fuel. On the other hand, they will be able to refuel, so they might opt to use more fuel in order to push more when needed.

[Pjeki @Pjeki_]

@jsolanesgarcia @Nachez98 How does refuelling impact cost? It doesn’t necessarily mean they’d be using more fuel.

@Rolando_tillit @ferrarinewstr @berrageiz I don’t disagree with existance of these structures. I just disagree with the point at which one of them is induced, and its cause. This was fun anyway

[Pjeki @Pjeki_]

@Rolando_tillit @ferrarinewstr @berrageiz I don’t think what you have drawn here is possible at this exact cross sextion. There is no pressure gradient that draws the fluid from underneath the footplate. If you think its pointless to continue discussing we can stop. I enjoyed this tbh

[Pjeki @Pjeki_]

@Rolando_tillit @ferrarinewstr @berrageiz There is no way that vortex rotating that way extends for the whole length of the foot plate

[Pjeki @Pjeki_]

@Rolando_tillit @ferrarinewstr @berrageiz Can you find me any image that shows that? I just can’t see why that would be happening.

[Pjeki @Pjeki_]

@Rolando_tillit @ferrarinewstr @berrageiz Do we agree about this?

[Pjeki @Pjeki_]

@Rolando_tillit @ferrarinewstr @berrageiz Can you please get the y-z cross section so we can compare lower and upper surface of footplate

[Pjeki @Pjeki_]

@Rolando_tillit @ferrarinewstr @berrageiz Yes, that itself indicates the vortex going from top to under the footplate. I never argued the inwash…

[Pjeki @Pjeki_]

@Rolando_tillit @ferrarinewstr @berrageiz Although here you can also see higher fluid velocity below the footplate which indicates lover pressure. Do you have the ability to get pressure plots instead of velocity plots?

[Pjeki @Pjeki_]

@Rolando_tillit @ferrarinewstr @berrageiz Sorry, I meant y-z cross section

[Pjeki @Pjeki_]

@Rolando_tillit @ferrarinewstr @berrageiz Yes, most of it inwashes because the vortex around the footplate is generally inwashing, so only the outermost section travels around the tire at that height.

[Pjeki @Pjeki_]

@Rolando_tillit @ferrarinewstr @berrageiz I meant the image of pressure plot x-z cross section near the trailing edge.

[Pjeki @Pjeki_]

@Rolando_tillit @ferrarinewstr @berrageiz If it was a somewhat flat plate then yeah, although it would still be in groundeffect. But this kind of footplate generates a vortex in the “half-pipe” region which itself is a low pressure area. I am quite certain that pressure below is lower.

[Pjeki @Pjeki_]

@Rolando_tillit @ferrarinewstr @berrageiz Moreover, vorticity shown here in circled area clearly shows inwash on the whole length of the bottom footplate surface. Again, that cannot happen with the vortex rotating the other way
