The Approximate Solution of the Self-Similar Problem for Radial Flow of Non-Newtonian Fluids through Porous Media

In this paper,we study the approximate solution of the self-simikar problem for radial flow of non-Newtonian fluids through porous media.Assuming that the fluids obey the exponential function law,we obtain an exact solution for the exponent n=0 and compare it with the approximate solution in ref.1].For n>1 and n<1,we obtain respectively approximate solutions.Some exampls are presented.
