Ok, thanks for the hint: so I will select the cross-sectional area of the air volume so that the projected area of the car is around 10% of it. But what about the length of the air volume? Is it enough to have 5 or 6 times the car wheelbase (with the car positioned towards the inlet... for instance at 1/3 of the whole length of the air volume) ?KeithYoung wrote:Most typically what I see people worry about is the "blockage".
Googling Wind Tunnel Blockage got me a ton of results.
I try to aim for 10% blockage or less. If you have a computer with low ram you may find yourself constantly battling with these issues like I do.
