Abstract

Numerical simulation of a backward-facing step flow for Re = 800, 1200, and 1600 was performed to investigate the three-dimensionality of flows in the transition Reynolds number range. Through flow visualization we conclude that the flow is almost steady and 2 dimensional at a Reynolds number of 800. However, for Re = 1200 and 1600, vortices with 3-dimensional structures are generated periodically and advected downstream along the bottom and top walls.
