liuyuxuan is on a distinguished road
as we know that there are 4 kinds of subgrid-scale model :
Smagorinsky-Lilly Model
Dynamic Smagorinsky-Lilly Model
Wall-Adapting Local Eddy-Viscosity (WALE) Model
Dynamic Kinetic Energy Subgrid-Scale Model

I have a problem to choose which one exact for our model.

so I really want to know the different bewteen this 4 models, especially for the low Reynolds flow.

Thank you in advance.

in my compuation with Re=6e4, Dynamic Smagorinsky-Lilly Model Wall-Adapting Local Eddy-Viscosity (WALE) Model Dynamic Kinetic Energy Subgrid-Scale Model do NOT make much difference. just do NOT use Smagorinsky-Lilly Model
