Abstract: This paper investigates the effects of radiation and chemical reaction on magneto hydrodynamic stagnation point flow over a porous stretching surface with convective thermal boundary condition. The nonlinear and coupled governing differential equations were solved numerically using the fourth order Runge-Kutta shooting method. Numerical results for the skin friction coefficient, the rate of heat transfer represented by the local Nusselt number and the rate of mass transfer by the local Sherwood number were presented whilst the velocity, temperature and concentration profiles illustrated graphically and analyzed. The effects of the velocity ratio parameter, magnetic field parameter, suction parameter, Prandtl number, radiation parameter, Schmidt number, reaction rate parameter and Biot number on the flow field were discussed.
