Abstract
The aim of the present study is to quantify the influence of large, ribbed wall roughness elements on the mean flow and heat transfer properties of a turbulent, supersonic boundary layer (M = 2.0). Fifteen test geometries, including one smooth and fourteen rough surfaces are tested using Schlieren, PIV and QIRT. Heat transfer measurements were obtained by the heated-thin-foil method, providing a constant heat flux boundary condition. The QIRT setup was designed to yield an accurate mapping of the surface temperature. It was observed that the geometries followed supersonic, single-cavity type flow classifications with clear, distinguishable flow features.
