Abstract

Wall roughness affects flow characteristics practically in all technical applications. In internal flows, the height of rough elements should be much smaller than the thickness of the shear layer (so called distributed roughness) and its influence on the flow cannot be directly simulated. Instead a model of rough wall is needed.
