The effect of suction and injection on unsteady natural convection boundary layer flow and heat transfer from a porous vertical flat plate with constant heat flux is investigated. The unsteadiness in the flow is caused due to constant heat flux between plate and ambient fluid. The governing partial differential equations are solved by an implicit finite difference method. It is found that, the unsteadiness and heat flux has significant effects on both skin friction parameter and surface temperature. In fact, these parameters are strongly affected by initial transient time – dependent flow. With the increase of stream wise coordinate, the velocity and temperature found to decrease in the case of suction while they increase in the case of injection
