Abstract

The roughness extension of Knopp, Eisfeld and Calvo (KEC) for k-omega type turbulence models has been applied to the flow through rough pipes, over a flat plate and around the NACA 65_2-2156 airfoil with a rough surface. The results are compared to predictions with the Spalart-Allmaras model with the Boeing roughness extension by Aupoix and Spalart (ASB). Good agreement with experiments has been achieved with respect to the influence of the roughness on the velocity profile, the skin friction coefficient and the loss in lift.
