Abstract

Abstract

In this paper the problem of two-dimensional viscous flows past a circular cylinder is studied by making use of the concepts and methods of non-linear dynamics.The critical Reynolds numbers for a steady flow to becomeunstable,and for chaos to appear are computed,and some statistical charac- teristics of chaotic solutions are evaluated.
