| 抄録 | In this study, the relation between vibration the self-induced oscillation and jet noise issuing from divergent nozzle were studied by the flow visualization, pressure measurement and noise measurement. The instantaneous flow visualization was taken by schlieren method. The pressure fluctuation of total pressure was measured by a pressure transducer assembled into a total pressure probe and further, the noise of sound pressure level for the linear scale was measured. The frequency of the pressure and noise were analyzed by FFT analyzer. As a result, it was found that the jet noise was influenced by the total pressure fluctuation. |
