含激波、旋涡和声波的复杂多尺度流动数值模拟研究

Numerical study for complex multi-scale flow with shock, vortex and sound wave

  • 摘要: 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。

     

    Abstract: 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 jet noise. The goal of our study is to reveal the mechanisms of sound generation.
