Abstract

A local analysis of the flow of power law fluids near corners is performed. The equation for the stream function is shown to allow separated solutions in plane polar coordinates. The radial behavior is shown to be algebraic and results are given for the exponent for different values of corner angle and power law exponent. In addition, the critical angle for the onset of an eddy structure is found as function of the power law exponent.
