Diffusion-Thermo Effects on Heat and Mass Transfer of Non-Newtonian Power Law Fluid past a Porous Flat Plate with Chemical Reaction

Abstract

The diffusion-thermo effects on heat and mass transfer of a laminar boundary layer flow of a non-Newtonian power law fluid past a porous flat plate in the presence of magnetic field with chemical reaction effects have been considered. A suitable set of dimensionless variables is used and similar equations governing the flow are obtained. The resulting the non-linear ordinary differential equations are first linearised using Quasi-linearization technique and then an adequate implicit finite difference scheme is employed to obtain a numerical solution for the ordinary differential equations. The Representative results for the velocity, temperature and concentration profiles illustrating the influence of various governing parameters are presented and discussed. Temperature rises with increase in Dufour number and the effect of Chemical reaction parameter is to decrease the concentration of the fluid.
