Effects of Variable Viscosity and Thermal Conductivity on MHD Free Convective Flow Past an Inclined Surface with Viscous and Joule Dissipation

Abstract

investigation has been made to study the effects of variable viscosity and thermal conductivity on the steady two- dimensional MHD free convection and mass transfer flow past an inclined semi-infinite surface in the presence of heat generation along with viscous and Joule dissipation. The partial differential equations governing the flow, temperature and concentration field of the problem are reduced to ordinary differential equations by using similarity transformations. The momentum, energy and concentration equations are solved numerically using shooting method along with fourth order Runge-kutta iteration scheme. The effects of various parameters viz. viscosity, thermal conductivity and mass transfer parameters on velocity, temperature and concentration field are presented graphically. Finally, the numerical values of skin-friction co-efficient, Nusselt number and sheerwood number are also calculated. Keywordsviscosity, Thermal conductivity, Dissipation and Mass transfer.
