Abstract:

The boundary layers produced on rough surfaces in adverse pressure gradients were investigated. The report contains experimental results obtained for a single surface roughness at three pressure conditions one at constant pressure and two having adverse pressure gradients. The mean velocity profiles in the boundary layer were measured by both Pitot tubes and hot wires. The longitudinal turbulence intensities were measured with a hot wire. The pertinent boundary layer parameters were calculated and are presented. Results were compared with available smooth wall data. Author
