Effect of variable viscosity on laminar convection flow of an electrically conducting fluid in uniform magnetic field

The flow of a viscous incompressible electrically conducting fluid on a continuous moving flate plate in presence of uniform transverse magnetic field, is studied. The flat plate which is continuously moving in its own plane with a constant speed is considered to be isothermally heated. Assuming the fluid viscosity as an inverse linear function of temperature, the nature of fluid velocity and temperature in presence of uniform magnetic field are shown for changing viscosity parameter at different layers of the medium. Numerical solutions are obtained by using Runge-Kutta and Shooting method. The coefficient of skin friction and the rate of heat transfer are calculated at diffferent viscosity parameter and Prandtl number.
