Im willing to bet that the dissaperance of the two wall separation is related to a change in the overall stagnation point of the wing. When the endplate is extended forward, more air is gets drawn under the wing and that probably resolved the separation.
So, question. When designing a spoiler, would it not make sense to make the wing part a tear drop shape, and have the end plates a bigger version of the tear drops? So have the same teardrop shape on the end plates, just bigger?
I guess the best way to answer this is, the wing profile is interacting with the air profile. If you take the perspective of the conformal mapping of the circulation that early mathematical models used to calculate lift the extrapolate that out to form the end plate of maximum effectiveness. I suspect the endplate will look more like the shape of the air it passes through the further the perimeter of the endplate is from the wing.
It doesn't really affect lift, it reduces skin friction drag though. This is significant at high speeds but almost negligible at the low speeds these wings operate. (Yes most race cars are still considered as slow (low Reynolds numbers) when compared to general aviation aircraft).
@@Michallote it affects separation. Also think about what you're saying affecting skin drag on the low pressure side of the wing would improve flow velocity and thus downforce.
@@Michallote If you improve the lift envelope with each little mod you make, by the time you add them all up you can have a significant improvement in overall performance of a wing.
The greatness of RUclips is to give place for such very specifc courses. You won't learn such things on Top Gear
Thank you so much for this beautiful video ❤
What a good video. I just hope some day i understand it.

well done
What about a small fillet radius where the wing meets the endplate? Works for planes.

Thanks, great video. Who is this Nagy? Ki ez a Nagy József? Köszönöm Thanks
