The unsteady MHD flow of a nanofluid past a moving vertical permeable semi infinite flat plate with constant heat source through porous medium in the presence of viscous dissipation is theoretically. We used two types of nanofluids namely Cu-water and Tio2-water are used. The suitable transformations are applied to convert the governing partial differential equations into a set of nonlinear coupled ordinary differential equations.. The transformed equations are then solved analytically by multiple perturbation techninique. The obtained results for the velocity, temperature and concentration are analyzed graphically for several physical parameters. The flow features and heat transfer characteristics for different values of the governing parameters viz. skin friction coefficient, local Nusselt number, and Sherwood parameter are analyzed and discussed in detail.
