Hello all,
In order to put wall-roughness in RANS k-ε model, i put it in nut folder, instead of nutkWallFunction to the walls ,nutkRoughWallFunkion.Is that enough?Do i need to change and another boundary condition in nut folder (or to another folder) in order to put correct the roughness. In addition, i put the roughness height at Ks.But i don't know what is the Cs coefficient. |
