Chemical reaction, mass transfer, and thermal conductivity on MHD flow due to point sink in the presence of heat source

Abstract

A theoretical investigation of the influence of chemical reaction, mass transfer, variable viscosity and thermal conductivity on MHD flow due to point sink in the presence of heat source is presented. The fluid viscosity and thermal conductivity are assumed to vary as inverse linear functions of temperature. The system of non-linear partial differential equations of the governing flow has been obtained and finally transformed into a set of ordinary differential equations using similarity transformations. This set of equations has been solved using Runga-Kutta fourth order method with shooting technique. The results showing the effect of physical parameters on velocity profile, temperature profile and concentration have been obtained and represented graphically to discuss in detail.
