The purpose of the present work is to study the magnetohydrodynamic (MHD) free convection boundary layer flow saturated in a Darcian-Forchheimer porous medium over a vertical flat plate in the presence of suction/injection effect. The set of the partial differential equations is transformed into ordinary differential equations by using similarity transformations with perturbation technique. Numerical solutions of these equations are obtained by employing the routine bvp4c of the symbolic computer algebra software MATLAB. For the four different cases of flows, namely, isothermal surface, constant flux surface, plane plume and flow generated from a horizontal line energy source a vertical adiabatic surface, the numerical results for the velocity and temperature profiles are discussed for two values of physical parameters, namely, the magnetic field parameter M, the suction/ injection parameter F.
