Finite difference solution of the mixed convection flow of MHD micropolar fluid past a moving surface with radiation effect

In this paper, we have studied the effect of radiation, magnetic field on the mixed convection flow of a magneto-micropolar fluid past a continuously moving surface with suction and blowing. The governing equations have been reduced to a system of nonlinear ordinary differential equations by similarity transformations, which have been solved numerically using finite difference method. The effect of important parameters namely, radiation parameter, magnetic parameter and Grashof number on the velocity, microrotation and temperature functions across the boundary layer are shown graphically. Numerical results are also obtained for the skin friction and for the rate of heat transfer, which are given in tables. It is found that skin-friction coefficient increases while the rate of heat transfer decreases as the magnetic parameter increases. The heat transfer coefficient increases with an increase in the radiation parameter. Key-Words: Boundary layer, Finite difference method, Mixed Convection, Radiation, MHD
