Komogrov time scale and implicit scheme for LES
 

Dear all,

I am now thinking if I could use the implicit scheme and the dual time step approach for a LES simulation. Can you tell me how to calculate the Komogrov time scale and how could I know if I could use an implicit scheme i.e a larger time step and I can still get a time accurate turbulent flow solution ?

Thank you very much in advance.
