Thermal progress of unsteady separated stagnation point flow with magnetic field and heat generation in hybrid ferrofluid

This paper examines the unsteady separated stagnation point (USSP) flow and thermal progress of Fe3O4–CoFe2O4/H2O on a moving plate subject to the heat generation and MHD effects. The model of the flow includes the boundary layer and energy equations. These equations are then simplified with the aid...
