摘要/Abstract

摘要： 通过高阶差分求解三维可压缩稳定性方程,数值研究了时间发展可压缩平面混合层的稳定性特征。以对流马赫数为压缩性参数,以Reynolds数为粘性参数分析了二者对计算流场稳定性的影响。比较了二维和三维,无粘和粘性扰动波等情况。部分计算同相关文献进行了对比,取得了一致的结果。

Abstract: The stability of temporally evolving compressible plane mixing layers is investigated numerically by solving the three dimensional compressible linear disturbance equations.A high order finite difference method is used.The effects of key parameters such as convective Mach number and Reynolds number on the stability characteristics of compressible mixing layers are analyzed.The comparsions between two and three dimensional,viscous and inviscid disturbances are presented.Part of the numerical results obtained here are in agreement with those of relative literature.

Key words: compressible mixing layer, stability analysis, temporal model
