Originální abstrakt

The CFD simulation of air flow over solid sinusoidal surface is presented. The flow conditions defined by Reynolds number based on bulk velocity (Re=6760) and the ratio of the wave amplitude to the wavelength (0.05) induces turbulent flow with adverse pressure gradients. These are large enough to cause flow separation. For these reasons the appropriate Reynolds-Averaged Navier-Stokes models were used. The profiles of velocity components, pressure and wall shear stress are presented in comparison with Direct Numerical Simulations results.
