Abstract

A theoretical analysis of the phenomenon of boundary layer separation flow in power law pseudoplastic non-Newtonian fluids was made. Bifurcation solutions for skin friction were numerically represented for parameters of velocity ratio and power law exponent. The results indicate that both superior and inferior solutions are noticeable and the solutions not only depend on the velocity ratio of the plate to the velocity of the free stream, but also on the power law parameter.
