Abstract

Particle Image Velocimetry experiments were performed to study the effects of surface roughness on a hypersonic (M = 7:2), low Reynolds number (typically Reθ = 3600), turbulent boundary layer. Two roughness types were used: diamond mesh and square bars, with roughness heights of about 136 and 102 viscous units, respectively. The streamwise velocity fluctuation normalized by the wall friction velocity indicated that there may exist significant compressibility effects at these Mach numbers.
