@Wouter Remmerie , thank you.Hi @Kingske
We didn't run a back-to-back simulation with & without air curtain, so I don't have info on the real difference. But I would guess it's in the order of magnitude of 1%.
I've attached a screenshot below where you can at least see an indication that the flow through the air curtain (blue arrow) is reducing the wake/turbulent area around the lower part of the tire.
But we have to be careful with conclusions, as we don't have a car model with blocked curtains and this lower area might see reduced wake because of other reasons.
Nevertheless, we do see proper airflow going through the air curtains, so if it's blocked, for sure there is at least some impact!
