N2 - Experiments were performed within Rutgers University’s Supersonic Wind Tunnel to visualize the unsteady flow over wall-mounted hemispheres, using high-speed schlieren imaging. Three hemispheres were tested with radii of 25.4, 31.8, and 38.1 mm, placed within the wind tunnel’s naturally developing turbulent boundary layer. These resulted in boundary layer thickness–to–radius ratios of 0.62, 0.49, and 0.41, respectively. The hemisphere flow field demonstrates many features that are characteristic of a traditional shock-boundary layer interaction, such as unsteady motion associated with the foot of the upstream separation shock and subsequent incipient separation. In addition, a strong reattachment shock emanates from the forward side of the hemisphere where flow reattachment occurs.
