This article explores the flow characteristics of peristaltic transport of two immiscible fluids in a vertical channel with heat transfer are studied. The flow domain is divided into the core region and a peripheral region, respectively. The solution is derived analytically in the form of temperature from which the stream function and axial velocity corresponding to each region are found. The two regions are separated by an interface, which is determined by using nonlinear algebraic equation. In peristaltic transport, the importance of physical quantities like pumping, axial velocity, temperature distribution, and interface are discussed for different considerations of interest governing the flow parameters. It is noticed that the increase in G r enhances the pressure change at a given flow rate. It shows that increasing G r enhances the displacement of fluid particles, which yields to increase in axial velocity. The increase in heat source/sink parameter yields the increase in temperature of the fluid, which, in turn, results in an increase in temperature distribution.
