NUMERICAL SIMULATION ON THE ACOUSTIC CHARACTERISTICS OF THE HARTMANN ACOUSTIC GENERATOR ARRAY

摘要：

　　Based on the method FW-H acoustic model,the acoustic characteristics of the Hartmann acoustic generator array were numerically calculated,with different inlet pressure 3.12atm,4.12atm,5.12atm,6.12atm,7.12atm and 8.12atm.The acoustic intensity empirical equations were introduced off the downstream,by nonlinear fitting the calculated intensity results about different inlet pressure.The test of significance was taken with F function,and the results show that the confidence level is at 10-4,and the regression level is high.The degree of belief of intensity empirical equations is high.The results of the paper are significant for the application of the Hartmann acoustic generator array.
