Could just be studying how air flows behind the bargeboard. Part of the validation process, you have to study what you're planning to focus on. Flowvis is the first step, that just shows you where they're looking at, likely already found something in CFD or the wind tunnel that they can improve in that area. So you test and see if stuff is doing what it's doing, then you start iterating in the background. There's a limited amount of airflow and getting enough to go to the floor is tricky, because the bargeboards can use some of that airflow themselves. Trying to get the best of both worlds so to speak will be the trick the nose is supposed to address. Big fat cape to channel as much airflow behind the bargeboards as possible(delaying the floor from stalling) so you can stop worrying and just have a really strong 250 vortex to energize the bargeboards.diffuser wrote: ↑Fri Nov 27, 2020 10:47 pmWonder what they changed there ?

Next year the bargeboard vortex will need to be stronger to make up for the floor area that will go missing so getting the airflow right at the front will be critical. McLaren already has a rear biased COG which makes them understeer at low speeds, perhaps the loss of the floor will make the car more pointy. Who knows.
