Default Hey Fluent Experts ! : On a turbulence issue
Posts: n/a
Need to ask you a question regarding a turbulent natural convection scenario inside a large hall.

Now, the simple question is: Does the k-w (Shear Stress Transport) model account for turbulent generation due to buoyancy?. In the fluent manual, the two-equation set for k and w do not show the term that accounts for buoyancy effect, unlike what you see in k-epsilon equations. While not sure about this, I understood from the manual that when I activate the k-w model, the software applies the k-w model for low Re regions and applies the k-e model in the free stream with buoyancy effect. Is this correct?.

Thanks in advance for your help.

Cheers Amr
