EFFECT OF VISCOUS DISSIPATION ON POWER LAW - FLUID PAST A PERMEABLE STRETCHING SHEET IN A POROUS MEDIA

Abstract

The steady, two dimensional, laminar flow of a power - law fluid over a permeable a stretching sheet in a porous media with constant heat flux in the presence of MHD, viscous dissipation. Using the similarity transformations, the governing equations have been transformed into a system of ordinary differential equations. These differential equations are highly nonlinear which cannot be solved analytically. Therefore, bvp4c MATLAB solver has been used for solving it. Numerical results are obtained for the skin-friction coefficient and the local Nusselt number as well as the velocity and temperature profiles for different values of the governing parameters, namely permeability parameter, power-law index parameter, Eckert number, Prandtl number.
