Influence of Rough Surface Morphology on Boundary Layer Flow
Original language description
The flow over nine different surfaces with sharp-edged roughness elements were measured by single wire anemometry. The intensity of turbulence did increase with the plan/frontal solidity of the roughness elements. We used a diagnostic plot to assess the quality of boundary-layer flows. All investigated boundary layers revealed linear dependence of the turbulence intensity on the relative mean wind speed in the outer layer. The slope of the diagnostic plot was dependent on the frontal solidity of the elements but not on their size. The intensity of turbulence exceeds the maximal slope of the diagnostic plot for rough-wall flows showed in (J. Fluid Mech.727:119–131) in six cases.
