I am working on tube flow with L = 1000 mm, D = 19 mm and tube thickness = 0.5 mm. I am using SST k-w model.
Now I want to use Wall Roughness case. There are two input needed. These are 1. Roughness height 2. Roughness constant. I set Roughness constant = 0.5. It means uniform roughness along the tube. But what is called Roughness height? How to calculate this? Any suggestions pls? |
