Yeah, I get the regulations try to limit it, but they can't stop it, just like endplates don't stop wingtip vortices from happening. You can't regulate physics into compliance, and if teams get more performance from combining outwash with upwash they're going to figure out a way to induce it within the regulations. The previous regulations limited diffuser upwash, so the teams used outwash to maximize the expansion ratio after the diffuser kick line.PlatinumZealot wrote: ↑22 Apr 2022, 05:50Diffuser designed for outwash looks like this:godlameroso wrote: ↑21 Apr 2022, 19:40https://pbs.twimg.com/media/FMSIv6yXoAg ... ame=medium
So that flow vis in the Ferrari diffuser, it's not going outwards? It looks like it's outwashing, especially at the top of the diffuser. Are my eyes deceiving me and is that actually inwash?

That sort of curvature of the walls is no longer allowed.
Look how wide the diffuser is relative to the brake ducts.

The new regulations want to encourage upwash, so they give you more diffuser height, and limit the outward radius of the side fences to practically flat. Even then, you see an outward taper on the inner wall to encourage outwash. At the top of the diffuser where the outwash isn't as tightly regulated, most teams are willingly exchanging diffuser volume for more outwash potential, because the upwash expansion is too great and causes separation.
