Hi to all

I am modelling a turbulent flow in a pipe. I used the standard K-Epsilon model.In the inlet I used groovy Bc(for the velocity) for turbulent flow. My aim is to see the effect of surface roughness on the velocity profile. So I used nutRoughWallFunction (0/nut) with different values of Ks and Cs but the velocity profile remain the same. I tried nutWallfunction and the result is the same.
coud any one help me with this issue ?
thanks in advanced
