Hello Everyone,
I am trying to calculate the time steps for LES but I am not sure of the way one should calculate. (No. of cells are 10 Millions). What I am doing is that, in calcuating the LES one concentrates on small scales i.e kolmogrov scales where in there is an option that we can calculate the length of the scale by considsering Re = 1 and computing it as 1= (Vel.*length)/viscosity I kno the viscosity and vel. and from here I calcuated the small scale length and Now I am unable to move further to calculate the time steps required. Please can anyone give me a solution to this problem. |
