| Abstract: | The oscillating mechanism of the jet induced by external excitation shear flow was described and the excitation condition was analyzed in this paper. Spectrum analysis was applied to investigate the pressure oscillations in the center of the jet which are measured in laboratory. It is shown experimentally that its oscillating amplitude is very large and the jet has broad frequency, Its erosive effect is superior to that of the ordinary jet. |
