Influences of Heat Transfer in Peristaltic Transport of Two-Layer Model

Abstract

 The two-layered peristaltic Transport and the heat transfer in the symmetric channel is analyzed. The core layer fluid satisfies the power-law fluid characterize and the peripheral layer is depicted as the Bingham flow model. The no-slip conditions at the walls are taken into consideration. For both zones, small Reynolds number and the long-wavelength approximations are used to simplify the governing equations. By using suitable methods, the interface equation between the two layers, the velocity, pressure gradient, temperature profile, and trapping phenomenon are studied. The influence of the physical parameters of the problem are debated and clarified graphically.
