摘要：
The research problems of computational aero acoustics mainly include acoustic source calculation, acoustic propagation calculation and acoustic radiation calculation. In this paper, the pipe acoustic source of the engine wake is modularized, and the numerical simulation of the spread of acoustic waves under different modals inside and outside of the pipe are given by using the computational aero acoustics method. Then, through the analysis of the calculation results, the method of noise control is obtained.
