Dear All,
I'm trying to calculate pressure drops in a straight pipe with CFX 14.0. I simulated two different cases with SST turbulence model: - in the first case I set Wall Roughness = Smooth Wall on the solid boundary; - in the second case I set Wall Roughness = Rough Wall (Sand Grain Roughness= 3mm). In the Post-processing I evaluated the pressure drop for the two cases and it resulted perfectly the same. How it possible? Thanks in advance. |
