ABSTRAKT

This article deals with the influence of an endoscope and magnetic field on the peristaltic flow of a viscous fluid through a porous medium. The mathematical model considers a magnetohydrodynamic fluid through a gap between concentric uniform tubes such that the inner tube is rigid and the outer tube has a sinusoidal wave traveling down its wall. The analysis has been carried out under the assumption of long wavelength and low Reynolds number. Analytic solutions are obtained for the velocity components and pressure gradient. The influence of sundry parameters is seen on the pressure rise per wavelength, friction forces on the inner and outer tubes, and axial pressure gradient.
