摘要
本文讨论了经过修正的平面Couette流在二维扰动下的非线性稳定性性质,并同经过修正的平面Poiseuille流的非线性稳定性性质进行了比较.计算结果表明,对于有限振幅的扰动,平面Couette流比平面Poiseulle流更不稳定.
This paper discusses the nonlinear stability behaviour of distorted place Cou-
ette flow to 2-dimensional disturbances, and compares it with that of distorted plane
Poiseuille flow. The results show that plane Couette flow is more, unstable than plane Poiseuille flow to finite-amplitude disturbances.
