Abstract

Abstract This research work investigates the effect of point/line heat source/sink on free convection flow between two vertical channels with suction/injection. The Heaviside step function is used to model the constant heat source/sink, which is then transformed into line source/sink. The governing equations describing flow formation and heat transfer are obtained and solved using the Laplace transform approach. The effect of physical parameters such as suction/injection, Prandtl number, and heat source/sink on velocity and temperature fields are studied graphically, while the skin friction, Nusselt number, and mass flowrate are analyzed through tabular representation. Results indicate that as the value of point/line source parameters rise, velocity and temperature profile of fluid flow are enhanced.
