A NEW METHOD FOR CALCULATING THE PARAMETRIC ARRAY’S SOUND FIELD

摘要：

Among numerous theory models for describing the parametric arrays near-field acoustic characteristics,the KZK equation is the most accurate theoretical model.However,the computation efficiency is low by using the frequency-domain method for the parametric arrays sound field.The paper drew ideas from the time-domain method to separate the operator,and calculated the KZK equations nonlinear term (inviscid Burgers equations) by the conservative upwind scheme integral method.Then,this paper used the numerical method mentioned above to study the parametric arrays near-field acoustic characteristics.The simulation results show that the results obtained by above method are highly consistent with the frequency-domain method,and the method can effectively reduce the calculation amount and improve the computational efficiency.
