Hi
Which turbulent models serve better in OBCs at low Reynolds number of 312? LES, K-Epsilon or DES? What's the major differences between these three models at this Reynolds number at 2D and 3D method?
Any suggestion would be most appreciated
Thanks

I dont know what you mean with OBCs, but according to http://en.wikipedia.org/wiki/OBC it could mean Oceania Badminton Confederation , Oriental Bird Club, Osaka Broadcasting Corporation or something else.
However, a Re at 300 sounds laminar to me, so dont use a turbulence model. And CFX cannot do "true" 2D.

Hi Lance
Thanks for your reply. OBCs stand for Oscillatory Baffled Columns (mixing columns). But it's nice to know what wiki can come up with.
