Bifurcation of the flow over a plane sudden symmetric expansion
Abstract
Experiments have been performed to investigate the fundamental steady flow phenomena over a plane sudden symmetric 1:3 expansion in a nominally two-dimensional channel. Highly accurate LDV measurements are used to provide detailed information of the changes in the features of the flow as the Reynolds number is varied. In particular, a careful study is made of the initial change from a steady symmetric state to either one of two steady asymmetric regimes by means of a symmetry breaking bifurcation. The experimental results for this bifurcation are supported by the results of calculations performed on the CRAY2.
