Abstract: Magnetohydrodynamic (MHD) forced convection heat transfer from radiate surfaces in the presence of a uniform transverse magnetic field, with conductive fluid suction or injection from a porous plate is considered. A set of solutions to the non-linear equations is presented using the Keller box method. It is found that increasing the magnetic influence number decreases both the velocity boundary layer thickness and the heat transfer rates from the porous plate, also increasing the radiation-conduction parameter, Eckert numbers, dimensionless temperature ratios, which heated the fluid, and decreases heat transfer rates. Different velocity and temperature profiles, local coefficient of friction, and local Nusselt numbers for different dimensionless groups are drawn.

Key Words: Magnetic field, Thermal radiation, Viscous dissipation, Forced convection
