抄録

In this study, the supersonic jet from a nozzle with different outlet divergent angles was visualized, and unsteady pressure and noise were conducted. The temporal averages and instantaneous flow visualization were taken by shadowgraph method. In addition, the pressure fluctuation and also occurrence of noise were examined by the change of the nozzle exit divergent angle and difference of the pressure ratio. As a result, the jet structure and also the relevancy between the self-excited vibration and jet noise were clarified.
