• PERISTALTIC TRANSPORT OF COUPLE STRESS FLUID IN UNIFORM AND NON-UNIFORM ANNULUS THROUGH POROUS MEDIUM

Abstract

The aim of present investigation is to study peristaltic transport through the gap between coaxial tubes, where outer tube is non uniform and inner tube is rigid. The necessary theoretical results such as viscosity, pressure gradient and friction force on inner and outer tubes have been obtained in terms of couple stress parameter through a porous medium. Out of these theoretical results the numerical solution of pressure gradient, outer friction, inert friction and flow rate are shown graphically for the better understanding.
