Abstract
Large-eddy simulation is used to study turbulent flow over a sinusoidal wavy wall from the perspective of surface roughness effects. Simulation results are averaged in time and space to obtain the so-called roughness function (shift in the logarithmic law), the equivalent sand-grain roughness and the virtual origin, and the dependence of these quantities on the amplitude-to-wavelength ratio. The results demonstrate the usefulness of LES to quantify roughness effects that have hitherto fore been the purview of laboratory experiments.
