Spatial density fluctuation of supersonic flow over a backward-facing step is studied by nanotracer planar laser scattering, aero-optic method and proper orthogonal decomposition analysis. Measurements were carried out in a Ma = 3.0 low-noise indraft wind tunnel. By varying the superficial roughness of the wall upstream from the step, supersonic laminar(More)
