Abstract

An experimental investigation has been conducted on the impingement of underexpanded, axisymmetric, and supersonic jets on a flat plate. The surface pressure and the adiabatic wall temperature distributions on the flat plate have been measured in detail at small nozzle-to-plate distances. The influences of the pressure ratio, the exit Mach number, the nozzle-to-plate distance, and the impinging angle have been considered. The results show that the surface pressure and the adiabatic wall temperature distributions on the flat plate for supersonic jet impingement are affected significantly by the nozzle-to-plate distance and the existence of a stagnation bubble in the central region.
