Influence of an external magnetic field on the peristaltic flow of a couple stress fluid through a porous medium.

Abstract

Magnetohydrodynamic(MHD) peristaltic flow of a Couple Stress Fluid through a permeable channel is examined in this investigation. The flow analysis is performed in the presence of an External Magnetic Field. Long wavelength and low Reynolds number approach is implemented.<br /> Mathematical expressions of axial velocity, pressure gradient and volume flow rate are obtained.<br /> Pressure rise, frictional force and pumping phenomenon are portrayed and symbolized graphically.<br /> The elemental characteristics of this analysis is a complete interpretation of the influence of Couple Stress Parameter, magnetic number, non dimensional amplitude ratio and permeability parameter on the velocity, pressure gradient, pressure rise and frictional forces.
