Default Roughness in Cebeci-Smith
Posts: n/a
Hey all,

Does anybody have any information on how to specify wall roughness in a Cebeci-Smith (or any other algebraic) turbulence model?

Any help is welcome! =) Biga

The usual way to do it is to replace y by y+y_0 in the mixing length. Here y_0 is the roughness length.
