Hey guys,
I'm modeling NREL wind turbine with SST model.
I have already finished my results and i want to know about the value of turbulence length scale using CFX-post.

Is it possible to know the value of it? how?

I need this value( values) ,because later I will use DES and I want to compare the results of these two models.

Any help and suggestion is welcomed in advance.

Yes, you can get the length scale by using K & epsilon or omega.

Length scale(k-epsilon) = k^(3/2)/epsilon
Length scale(k-omega) = k^(1/2)/omega
