Turbulence in Oscillatory Boundary Layers
This paper reports the results of an experimental investigation on the turbulent oscillatory boundary layer flows which occur over both the smooth and rough walls, the rough wall case having a roughness parameter, the amplitude-to-roughness-height ratio of 1800. The boundary layer properties are found to be strongly dependent on the phase as well as on the wall category.
