Hello,
I would like to add roughness to a wall, I am not sure what sand grain roughness is trying to represent. Can anyone tell me how this correlates to absolute roughness? If my absolute roughness of my wall is 0.000125 inches what will my sand grain roughness be? Thanks |

Hopefully this helps!! you will need to go thru some literature though.

CFX has a wall roughness model in several turbulence models. Read the documentation for details.
