Thank you guys so much!
Here is my development over the season:
Red arrows indicate the geometries I submitted. The ones in the grey box were run with the wrong rideheight (If you remember in the beginning of the season). Also, I ended up submitting the same car for round 4 and 5. From the looks of it, I subscribe to the same strategy as Max. I only make small changes, and run lots of simulations.
Again this season, cooling was a very important factor. So, here is something some of you might wanna consider. I added turningvanes to help redirect the air into the radiator
This is the U: 0->20 m/s slice.
They are essentially wings at 0 aoa, so it adds a little downforce with negligible drag. The upwash also helps with cooling. From the results:
radiator_turningvanes_v3 - Cd: 0.000084, Cl: -0.051, Cl/Cd: -608
I would be very interested in hearing what the rest of you guys think about the bargeboards/floor fences
imo, there is little reason to add another fence when the front tyre wake looks like this ^
How did you guys manage the tyre wake? I see many of you floor fences way further outboard compared to mine.
