| 摘 要： | On the hypothesis that the turbulent flow is practically not affected incharacter by pulsation of the flow,the formula for sound pressure level of pulsedjet noise is obtained in 90°direction and 1 meter away from the nozzle.Thesteady jet noise is,then,a special case when the pulsating frequency is zero.Theresults agree well with experiments. |
