Radiation effect on MHD free-convection flow of a gas at a stretching surface with a uniform free stream

Abstract

We investigate the problem of free convection heat transfer near an isothermal stretching sheet. This has been done under the simultaneous action of buoyancy, radiation, and transverse magnetic field. The governing equations are solved by the shooting method. The velocity and temperature functions are represented graphically for various values of the flow parameters: radiation parameterF, free convection parameterGr, magnetic parameterM, Prandtl numberPr, and the parameter of relative difference between the temperature of the sheet, and the temperature far away from the sheetr. The effects of the radiation and magnetic field parameters on the shear stress and heat flux are discussed.
