I was always so fascinated with airflow and how to study and in turn manipulate it. I tried my hand and joining the formula team at San Jose State University but failed in my 3rd day due to not knowing anything about it. I can't afford a course either so I'll just sit back with my coffee and watch these videos 🥲
I just wanted to ask you, what post-processing tool are you using (in general, for example for the video series analyzing the floor fences and the f1 2022 regulations). I am thinking of using that for my post-processing for my master's thesis! In any case, great videos!
The flow at the floor edge is getting sucked under the floor, the pressure above it is higher. The pressure difference above the floor and below it, gives you the total downforce. You want slow stagnant high pressure air to pile up ahead of the rear suspension, because then the fast low pressure air under the car creates massive suction. What you don't want is that air getting sucked under the car, because it will raise the pressure of the underfloor. So you take that piled up slow stagnant air, and you shove it behind the tires, that way it doesn't interfere with the fast low pressure air going under the floor. Air does what it wants, you have to work with the air, not force it to do what you want, otherwise you take too much energy out of the airflow. The regulations both encourage and force you to create outwash behind the tire, whereas in the old regulations you had freedom to do this ahead, within, and behind the tire. The front wing works in combination with the wheel brows and winglets and the floor leading edge to manage the wake of the tire. In the rear, the sidepod, suspension, wheel furniture, rear wing end plate, and diffuser wall, all work to do the same thing as the stuff at the front. The flow at the rear also has to be high energy so that it can be converted to pressure energy, and back to kinetic energy, to force air through the diffuser expansion. This lowers the back pressure of the diffuser forcing the floor to work harder, kind of like how the beam wing enhances the diffuser.
The airflow that get's sucked into the mouse hole is primarily under the floor if you can believe it, the airflow above is a higher pressure and stagnant, so some of it does go back there, but it's being entrained by the air under the floor.
Your CFD shows a pair of downwashing vortices at the rear wing leading edge, it could be why teams are going with the spoon shape. At lower speeds, the downwash alters the flow the wing sees, meaning it's no longer going dead on but down a bit altering the effective angle of attack.

I am definitely of YT. Do I have a personality? that is debatable. 😅

🥲🤧🥺🤧good luck to you in future!
Amazing! 👏👏
Fantastic work! Keep it up

Its paraview and its pretty good, used by many in the scientific field/s.
@@nelsonphillips Thank you!!
