Abstract
The object of this paper is to analyse the effect of temperature dependent fluid’s properties on a radiative magnetohydrodynamic flow of a fluid in an open ended vertical channel and permeated by a uniform transverse magnetic field. The solution for the temperature difference velocity and induced magnetic field are obtained in an optically thin-limit case using analytical successive approximation method. It is found that an increase in viscous dissipation heat parameter, when the thermal conductivity is a function of temperature causes corresponding increase in heat transfer, temperature difference but a decrease in flow rate, velocity and induced magnetic field. Also, an increase in viscous dissipation heat parameter, when the viscosity is temperature dependent results in an increase in flow rate, heat transfer, velocity, induced magnetic field and temperature difference. The result in [2], for constant fluid parameters is obtained as a special case.
