In this paper, the unsteady MHD free convective rotating flow of nanofluids (Cu-water and Al2O3-water) in a porous medium bounded by a moving vertical semi-infinite permeable flat plate with constant heat source and convective boundary condition is studied. The slip velocity is assumed to oscillate in time with constant frequency so that the solutions of the boundary layer are the same oscillatory type. The equations for the governing flow are solved analytically by perturbation approximation. The effects of various parameters on the flow are discussed through graphs and tables.
