The Stability of Parallel,Quasi-Parallel and Stationary Flows.

摘要

The methods of linear perturbation theory have been used to study the stability of various flows,among them being (1) The stability of boundary layers along concave heated walls; (2) The stability of boundary layers along concave walls with suction; (3) The stability of wall jets along concave and convex walls; (4) The spin up of a two-dimensional cylinder in an infinite medium; (5) The stability of stationary layers of fluid with arbitrary temperature stratification; (6) The stability of natural convection flow along inclined plates. During the course of this work,three different solution techniques were employed;one of them was an approximate analytic technique,the remaining two were numerical. Three-dimensional spatially and temporally amplifying disturbances were considered in the study. (Modified author abstract)
