Supersonic Jet-Wall Interactions

        The aerodynamic aspects of the flow, formed after angled impingement of an axsymmetric supersonic jet onto a flat plate, have been studied with emphasis on the shock structures and interactions with the approaching jet. The general features of the flow field were examined qualitatively by shadowgraph images for the jet which was exhausted from a convergent-divergent nozzle of 20 mm exit diameter with a Mach number of 2 and under expansion ratio between 1.08 and 1.60, and impinged to the plate at angles 0, 10 and 15 degrees with nozzle-to-plate distance to nozzle exit diameter ratios of 3 and 4.
