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! :o
ty for your time
i edited the question cuz i got the answer to those ones.. thx..
now i need a hand with those two new ones :D
