The Impingement of a Two-Dimensional Supersonic Jet upon a Normal Ground Surface

A brief report is presented of experimental work on rectangular supersonic jets of nominal Mach no. 1.4 under freely discharging conditions and also impinging upon a normal ground surface. The mixing region and the fully developed region of the free jet are investigated and show good agreement with other authors' work. The pressure distribution on the ground surface under the impinging jet is correlated for various nozzle heights above the ground on the basis of a dimensional argument. Finally, some results of a numerical prediction for the shock-wave shape in the impingement region are also presented.
