Surface roughness and y+

Hi!
I have added surface roughness in my k-omega sst model and I don't know how to think about the y+ value. For a smooth pipe it should be around 1, but I can't get it below 20 with my added roughness and I can't find any information about this when I try to google, only for the wall functions but not when I want to be in the viscous layer. Would really appreciate some insight in this and how to think or if anyone know where I can find information about the y+ for the k-omega sst model with roughness. Thanks!! |
