Abstract
In this study, the results were discussed of experimental investigation of supersonic jet. The jet becomes underexpanded when the pressure ratio exceeds the critical value across the convergent nozzle discharging it. The jet is not uniform because of the presence of the expansion wave, the compression wave and the shock wave formed in it. In this experiment, the flow field is experimentally visualized in order to analyse the behavior of jet.
