Effect of magnetic field on peristaltic flow of Williamson fluid through a porous medium in an inclined tapered asymmetric channel.

Abstract

Effects of magnetic field on peristaltic flow of Williamson fluid through a porous medium as well as effects of non-slip and heat transfer are considered in an inclined tapered asymmetric channel. The problem is studied under long wave length and low Reynolds number assumption, the perturbation technique is used to solve the problem as the equations are non linear. The stream function, the temperature distribution and the pressure rise are calculated. The effect of various parameter on the pumping characteristic and on the temperature profiles as well as stream functions and velocity profiles are discussed with the help of graphs.

Keywords: Williamson fluid, Peristaltic transport, magnetic field, porous medium , non-slip effects, heat transfer, an inclined tapered asymmetric channel.
