Dear Users,
i have a problem with the drag coefficient calculated by the kOmegaSST turbulence model with the simpleFOAM solver :-( The aim is to get to know about the drag coefficient of a streamlined body and compare this results with the ones got by the same body out of a wind tunnel experiment. So in fact - compare reality an CFD The coefficient i should get for cd is about 0.07, the one i got from my calculations is somewhat around 0.96... I have calculated values for k and omega from the formulas out of the CFDWiki, but they seem to be incorrect - or a BC is the problem - i don't know The eddy viscosity ratio i took was 1, but i don't know if this is correct for wind tunnel experiments...? I will post my case files - maybe someone do have an idea...!? Thank you very much in advance Regards, Martin |
