We can set the roughness height for ""No-slip" wall. What is the specific formula for the wall function that reflects the roughness height?
Are there any webpages or documents that compile such information?
There's a small statement on roughtness_height in the SIMPLE_BOUNDARY_CONDITION and TURBULENCE_WALL commands:

The roughness_height parameter is a dimensional distance/height.
Here's another brief description of the turbulence models, but not with much detail:
