Abstract

PIV measurements of the velocity field of a supersonic jet impinging on a flat surface were conducted for a pure convergent nozzle with a nozzle pressure ratio of NPR=3.4 and a nozzle to plate spacing of Z/D = 5.0. The velocity field at a center plane of the jet was resolved at a highspatial resolution of 0.012D in the streamwise and radial directions. The paper reports the complex flow structure as well as the lower- and higher-order statistics.
