摘要：This paper investigates the effect of heat source and variable suction on unsteady viscous stratified flow through a porous medium due to a moving porous plate under slip boundary condition for velocity field and jump in temperature field. The velocity of the porous plate decreases exponentially with time about a constant mean and a variable suction velocity is applied normal to the plate. The governing equations of the flow field are solved using perturbation technique and the expressions for velocity field, temperature distribution, skin-friction and heat flux are obtained. The effects of the pertinent parameters such as permeability parameter (Kp), velocity slip and temperature jump parameter (h1, h2), stratification parameter (alpha), suction velocity parameter (A), the heat source parameter (S) and Prandtl number (Pr) on velocity and temperature distribution of the flow field and also on skin-friction and the rate of heat transfer are analyzed and discussed with the aid of figures and table.
