Mechanism of Momentum Exchange near a Roughness Element for Rough Wall Turbulent Boundary Layer

Flow visualization has been performed in the vicinity of a roughness element for boundary layers developing over rough surfaces with roughness pitch ratios p of 2 and 4 at low Reynolds number. The momentum thickness Reynolds numbers at streamwise distance x=865 mm for p=2 and 4 are 300 and 500, resp...
