Abstract

This paper analyzes the 2-D Stokes flow in annular wedge cavities with different cavity angles. In order to analyze the flow structures, the two dimensional biharmonic equation is solved analytically. The flow is governed by two physical control parameters: the cavity angle α and the ratio of the upper and lower lid speeds (S = U1 U2 ). By varying α for each S, the effect of cavity angle on the streamline patterns and their bifurcations are investigated
