The CFD plots are in the aero regs thread (they were posted a couple of weeks ago). The front wheel wake appears to be fairly well ‘down-drafted’ by the front wheel deflector, so could well end up in the vicinity of the undercut lead in. And I do mean the aero winglet appendages on the inner face of the rear wheel.jh199 wrote: ↑Sun Feb 06, 2022 3:09 pmWouldn't the 'side-wing' only control the turbulence near the floor? Leaving the majority of the upper front tire wake to interfere with the rear wing as it's drawn toward the body? And when you say rear wheel 'deflectors', are those located on the inside of the rear tires?Stu wrote: ↑Sun Feb 06, 2022 8:12 amAlmost!jh199 wrote: ↑Sun Feb 06, 2022 1:03 amCan someone clarify what y'all are talking about when you say the sidepod shape will push the front tire wake outboard? I don't see how this would work. The sidepods are wide, yes, but they're still lower than the top of the tires (allowing some tire wake to flow into the void left behind the sidepod) and still feature a pretty substantial undercut. To me, this would mean that the clean air wraps around the top and bottom of the sidepods, not really creating a wall of air to keep the front tire wake away.
In the photos below, I would expect the air from the centerline to wrap over and around the sidepods (blue), the adjacent air to wrap down the sidepod and move toward the floor (green), some air would go straight into the sidepod (yellow), and then the lower air would go down and around the sidepods or under the floor (orange). I don't see how air would travel around the outermost section of the sidepod to push the tire wake outboard. Further, the massive void left behind the sidepods should then bring some of the tire wake toward the rear wing. Right?
From CFD plots that I have seen (on this forum) of how the front tyre wake behaves with the new regs the tyre wake will be drawn into the undercut area on the Haas.
If it works how I think it could/should the small ‘side-wing’ that the regs allow along the floor edge will then re-energise that flow into a vortex along the floor edge which then flows to the rear of the car exiting roughly where the rear wheel ‘deflectors’ are located.
Also, where can I find those CFD plots you speak of? Is it somewhere in the aerodynamic regulations thread?
If I can link the CFD part here I will. Big thank you to @blackout for posting it originally.
