I have never run CFD myself but many times, colleagues would feed me CFD data that would end up getting tunnel or road tested. It’s a great tool that I always say I will learn more but man, there is just to much to learn.
My experience has been it is a GREAT tool to hypothesize what to test in the real world but it does not replace real world testing.
Would I make a decision based on what CFD tells me : no. Would I build my test matrix based on it : absolutely.
Very specific to your analysis above : did you/can you run them at yaw ?
