Abstract

Experimental investigations of supersonic flow over a 25° compression ramp were carried out in a Mach 3.0 wind tunnel; the upstream boundary layer was laminar flow. Wall pressure was measured; fine structures of holistic flow field and local regions were visualized by nanoparticle-tracer-based planar laser scattering (NPLS) technique. The analysis of two NPLS images with 10 μs time interval revealed the spatiotemporal evolution characteristics of flow field; the angle of separation shock and reattachment shock and the development of boundary layer were measured by time-averaged flow field. Density distributions were obtained based on NPLS images, the instantaneous density field was corresponding to flow structures, and the statistically averaged density field was layered. Velocity field structures were obtained using particle image velocimetry (PIV) technique, reversed flow in separation region was revealed by streamlines, and the variations of velocity vectors revealed velocity shear.
