摘要：In this work a numerical solution is developed for the incompressible laminar
flow of non-Newtonian power-law type fluids through a 2D channel with a
sudden asymmetric expansion. A finite volume approach, with the SIMPLE
method, is implemented and tested for power-law fluids, and compared against
the Newtonian behavior. Velocity profiles are presented for a range of
Reynolds numbers, power-law exponents, and geometric expansion ratios. The
results for recirculation, reattachment and pressure distributions on the walls
are also presented.
