Time-Resolved Planar Velocimetry of the Supersonic Wake of a Wall-Mounted Hemisphere

Time-resolved particle image velocimetry was conducted at 40 kHz using a pulse-burst laser in the supersonic wake of a wall-mounted hemisphere. Velocity fields suggest a recirculation region with two lobes, in which flow moves away from the wall near the centerline and recirculates back toward the h...
