Description	The work deals with numerical solution of incompressible and compressible turbulent flows over rough walls. The mathematical model is based on averaged Navier-Stokes equations with two-equation SST or EARSM turbulence models. The low-Re versions are used and the wall roughness is modelled by means of the boundary condition for specific dissipation rate. The numerical solution is obtained by means of implicit upwind finite volume schemes. The presented cases are incompressible constant-pressure boundary-layer flow, incompressible flow over a ramp with flow separation and compressible flow through a turbine blade cascade. The comparison of the numerical solution with experimental data shows that the adopted roughness model is well suitable for both used turbulence models.
