Effects of heat and mass transfer on MHD peristaltic flow of a non-newtonian fluid through a porous medium between two coaxial cylinders

Abstract

We investigated the influence of heat and mass transfer on the peristaltic flow of magnetohydrodynamic Eyring-Powell fluid under low Reynolds number and long-wavelength approximation. The fluid flows between two infinite cylinders; the inner tube is uniform, rigid, and rest, while the outer flexible tube has a sinusoidal wave traveling down its wall. The governing equations are solved numerically using finite-difference technique. The velocity, temperature, and concentration distribution are obtained. The features of flow characteristics are analyzed by plotting graphs and discussed in detail. © 2013 Abeer A. Shaaban and Mohamed Y. Abou-zeid.
