Abstract

Flow patterns in a symmetric two-dimensional wavy-walled channel were investigated by flow visualizations at low Reynolds numbers and intermediate Strouhal numbers: Re=10–300 and St=0. 008–0.05. For steady flow, we discovered a new flow structure consisting of a regular three-dimensional flow as the Reynolds number exceeds 27.5. For oscillatory flow, the critical value of the Reynolds number at the onset of three-dimensional flow increases with the Strouhal number.
