PIV Study of Adverse and Favorable Pressure Gradient Turbulent Flows Over Transverse Ribs

This paper reports an experimental study of the combined effects of rib roughness and pressure gradient on turbulent flows produced in asymmetric converging and diverging channels. Transverse square ribs with pitch-to-height ratio of 4 were attached to the bottom wall of the channel to produce the r...
