近年来针对激波噪声计算,我们开展了较为系统性的数值方法研究,解决了计算激波噪声的一些方法上存在的问题.通过对典型问题的直接数值模拟,包括旋涡之间相互作用、激波与旋涡相互作用、激波与剪切层相互作用等模型问题和超声速喷流激波噪声问题,揭示了一系列激波噪声产生机理.本文对这些研究进行简要回顾.%In this paper,we give a brief review to our study on the numerical scheme for shock associated noise,as well as the direct numerical simulation on the interaction between two vortices,a shock interacting with one or more vortices,the interaction of a shock and a shear layer,and a supersonic j et noise.The goal of our study is to reveal the mechanisms of sound gen-eration.
