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
