MAGNETOHYDRODYNAMIC BOUNDARY LAYER HEAT TRANSFER TO A STRETCHING SHEET INCLUDING VISCOUS DISSIPATION AND INTERNAL HEAT GENERATION IN A POROUS MEDIUM

ABSTRACT

An analysis has been presented to study heat transfer in the laminar boundary layer flow over a nonisothermal stretching sheet in the presence of a transverse magnetic field acting perpendicularly to the direction of fluid. Viscous dissipation and internal heat generation effects are considered. The governing momentum and energy equations are solved based on the method of successive approximations. Velocity, temperature, skin friction coefficient, and local Nusselt number are discussed for various values of surface mass transfer fω, Alfven velocity α, Darcy number Da, Prandtl number Pr, Eckert number Ec, heat generation coefficient Qo, and relaxation time parameter τo. Numerical results are given and illustrated graphically for the problem considered.
