Abstract

An attempt has been made to investigate the heat and mass transfer through a porous medium in the presence of Magnetohydrodynamic flow and chemical reaction. On the basis of certain assumptions, the momentum, energy and concentration equations are obtained. These governing equations are transformed into ordinary differential equations using self-suitable transformations and these resulting equations are solved numerically using shooting procedure with fourth order Runge-Kutta Method. The effect of various non- dimensional parameters like magnetic parameter (M), Schmidt number (Sc), Chemical reaction (Kr) are discussed with the help of graphs.

Summary

Introduction

The Magnetohydrodynamics flow plays a vital role in engineering fields such as heat exchanger devices, petroleum reservoirs, chemical catalytic reactors and processes, geothermal and geophysical engineering, aerodynamic engineering and others. Santosh Chaudhary and Pradeep Kumar [9] has extended the work of Andersson[1], who has studied the effects of slip boundary layer stagnation point flow and heat transfer towards a shrinking sheet. Santhosh et al.[9] has discussed viscous incompressible, electrically conducting fluid near a stagnation point past a shrinking sheet with slip in the presence of a magnetic field. Mallikarjuna et al [6] investigated the numerical approach of an unsteady MHD convective flow on heat and mass transfer of circular cone through porous medium in the presence of chemical reaction. Mohanty et al [7] depicted the study of unsteady heat and mass transfer characteristics of a viscous incompressible electrically conducting micropolar fluid through porous medium in the presence of viscous dissipation using numerical method
