【Abstract】

<正>Stability of a two-dimensional channel flow with longitudinal wall-oscillation is investigated using the Floquet theory.To do this,time dependent Orr-Sommerfeld equation is derived from the disturbance equation by the use of the collocation method.Since the system is fundamentally linear,the velocity profiles at each instant are given from the linear superimposition of exact solution
