EFFECT OF ROUGHNESS ON THREE-DIMENSIONAL TURBULENT BOUNDARY LAYERS

A three-dimensional boundary layer experiment on a rough surface is described. The data obtained are compared with the results of a reference experiment having the same geometry and flow conditions, but a smooth surface. The boundary layer data are compared using scaling criteria developed from two-dimensional flows. It is found that the results agree well in regions where pressure gradients are the dominant cause of the three-dimensionality, but there are significant deviations in regions where shear stresses are more important.
