摘要: 主要研究可压缩流平面Couette-Poiseuille流的不稳定性.利用线性算子的扰动理论,得到当上板的速度小,且马赫数和雷诺数满足一定关系时,可压缩流平面Couette-Poiseuille流扰动问题是不稳定的.

关键词: 不稳定性, 可压缩Navier-Stokes方程, 平面Couette-Poiseuille流

Abstract: In this paper, we consider the instability of Plane Couette-Poiseuille flow of compressible Navier-Stokes equation. By the perturbation theory of linear operator, when the board speed is small, Mach number and Reynold number satisfy some condition, it turns out that plane Couette-Poiseuille flow of compressible Navier-Stokes equation is unstable.

Key words: Instability, Compressible Navier-Stokes Equation, Plane Couette-Poiseuille Flow
