Steady State Free Convection with Heat and Mass Transfer in the Presence of Variable Thermal Conductivity

Abstract

The steady state free convection flow in a vertical channel with heat and mass transfer in the presence of uniform magnetic field applied normal to the flow region and temperature dependent variable thermal conductivity has been investigated in this paper. The nonlinear partial differential equations together with the boundary conditions are reduced to dimensionless form. Approximate solutions have been derived for velocity, temperature, concentration, Skin friction, Nusselt number, and Sherwood number are presented graphically and discussed quantitatively for various parameters embedded in the problem
