The effect of variable viscosity on hydromagnetic flow and heat transfer past a continuously moving porous boundary with radiation

The effect of variable viscosity and magnetic field on the flow and heat transfer past a continuously moving porous plate in a stationary fluid taking into account the radiation effect has been analyzed. The fluid viscosity is assumed to vary as an inverse linear function of temperature. By means of the similarity solutions, deviation of the velocity and temperature fields as well as the skin friction and heat transfer results from their constant values are determined numerically by using the shooting method. The effects of variable viscosity, radiation, magnetic and suction (or injection) parameters on the velocity and temperature profiles have been studied.
