Replies: 220 LES of turbulent channel flows Views: 62,217 Posted By syavash Implicit and Explicit SGS Stress Hi, I think this is a quite important subject. I have tried to simulate channel395 through both dynamic Smagorinsky (local) and an explicit SGS stress tensor adding to momentum equations. The...
