Convective and peristaltic viscous fluid flow with variable viscosity

Abstract

In the present investigation we have analyzed the peristaltic flow when the viscous fluid with variable viscosity is bounded with convective walls. The combined effects of thermaldiffusion (Soret effects) and diffusion-thermo (Dufour effect) are considered. Convective form of the heat and mass transport phenomenon has been given special attention in addition to the effects of magnetic field. Mathematical formulation for the physical systemis derived and simplified using long wavelength and low Reynolds number approximation. Series solutions for the velocity, temperature andmass concentration fields are computed and elaborated for different physical quantities including magnetic parameter, Soret and Dufour effects, Biot numbers, etc. Streamlines analysis is presented showing the effects of bolus movement.
