Hello ccm users!!! Greetings!

i have a different question regarding the drag assessment of a car - underhood: by using a no-slip wall with speed equal to the mainstream velocity beneath the wake, make too much difference in the drag estimate? i usually set the whole floor to no-slip v=0m/s.

Also, by using a MRF, instead of the momentum source to model the pressure variation across the fan patch, do we have a significantly difference in the results? whats the best approach MRF or fan modeling, say for a top speed condition?? if using a MRF what should be the rpm?


sry for the big post...

any comments are most welcome!

ty for your time
