The present paper deals with the study of boundary layer flow behaviour with non-darcy forced and MHD free convection and mass transfer flow of an incompressible, viscous fluid past a continuously moving infinite vertical porous plate in the presence of large suction and under the influence of uniform magnetic field considering heat source and thermal diffusion. The presence of non-darcy forced convection leads to coupling and high nonlinearity in the boundary value problem. Because of the coupling and nonlinearity in the proposed intricate mathematical problem we have introduced usual similarity transformations by which the equations of momentum, energy and concentration are made similar. To obtain local similarity of the problem the similarity equations are solved using perturbation technique. The velocity, temperature and concentration fields are shown graphically to observe the effects of various parameters entering in the problem. The skin friction coefficient rate of heat and mass transfer are also obtained. One of the important observation is that the inertia parameter has a significant influence on the flow in reducing the boundary layer velocity and increasing the rate of heat transfer. Finally a thorough discussion of different results is presented.
