Abstract

This paper investigates the flow, heat andmass transfer of a power law fluid from a vertical plate in presence of a magnetic field. The resulting non-linear partial differential equations governing the flow together with the boundary conditions are reduced to non-dimensional form. The governing equations are discretized using implicit finite difference scheme and solved numerically. The velocity, temperature and concentration profile are presented graphically while the skin friction, local Nusselt number and the Sherwood number are presented in tabular form for different values of parameters of the problem.

Highlights

The fluids which are encountered in chemical and allied processing applications are known as non-Newtonianfluids
The problem of steady flow and heat transfer in power law fluid by free convection along a vertical plate has been investigated by many researchers
Naseer [5] investigated the problem of unsteady free convection with heat & mass transfer from an isothermal vertical flat plate to a non-Newtonian power law fluid immersed in a saturated porous medium

Summary

Introduction

The fluids which are encountered in chemical and allied processing applications are known as non-Newtonianfluids. Naseer [5] investigated the problem of unsteady free convection with heat & mass transfer from an isothermal vertical flat plate to a non-Newtonian power law fluid immersed in a saturated porous medium. Chamkha et al [6] investigated unsteady natural convective power law fluid flow past a vertical plate embedded in a non-Darcian porous medium in the presence of a homogeneous chemical reaction. Khan et al [7] discussed non-Newtonian MHD mixed convective power law fluid flow over a vertical stretching sheet with thermal radiation, heat generation and chemical reaction effects. Olajuwon et al [8] studied convection heat mass transfer in a power law fluid with non-constant relaxation time past a vertical porous plate in the presence of thermo and thermal diffusion. Madhu et al [12] studied effect of viscous dissipation and thermal stratification on chemical reacting fluid flow over a vertical stretching surface with heat source
