Forced Flow of a Non-Newtonian Second-Order Fluid between Two Infinite Discs with Exponential Porosity Ratio

Abstract

The steady forced flow of an incompressible second- order fluid between two infinite discs with
exponential porosity ratio has been considered. The obtained non-dimensional governing differential
equations are solved by regular perturbation technique assuming flow Reynolds number as
perturbation parameter. The effects of second order parameters (  1 2) , forced and porosity
ratio parameters M and eN respectively on the velocity components have been investigated.
