多重尺度法在平面Couette流稳定性分析中的应用

The Application of Multi-Scale Perturbation Method to the Stability Analysis of Plane Couette Flow

本文用文［３］所建议的多重尺度法分析了经过修正的平面Ｃｏｕｅｔｔｅ流动的线性稳定性性质。在平面Ｃｏｕｅｔｔｅ流的分析中，用多重尺度法可以找到不稳定的Ｔｏｌｌｍｉｅｎ－Ｓｃｈｌｉｃｈｔｉｎｇ波，但却不能找到最不稳定的模态，通过与文［３］相比较，本文对这种方法进行了探讨。

This paper applies the multi-soale perturbation method suggested suggested by Ref。[3] to investigate the linear stability behavior of distorted plane Couette flow.Using this method,the unstable Tollmien-Schlichting wave in plane Couette flow can be found, but not the most unstable mode.By comparing the results of this paper with those of Ref.[3]the effectiveness of this method is investigated。
