You can perhaps monitor the dissipation vs iterations just to double check the convergence but I doubt that is the case. Convergence of k and epsilon are usually very fast relative to momentum...

In that case Cmu of 0.09 is correct. yp is the distance to the nearest wall (m) correct? Did you also check the calculation of turbulent kinetic energy? It...

Are you using standard wall functions or enhanced wall functions? If enhanced, did you take the blending/damping function into account? That formula you referenced is correct for the low-Re...

Bruce, a user specified wall boundary condition is in some sense still a wall function. What I mean is that you cannot specify boundary conditions without specify variables at (at least) some cells...

Doesn't that already do what you need it to do? Fluent uses y* ~...
