• EFFECTS OF MAGNETIC FIELD WITH VARIABLE VISCOSITY AND AN ENDOSCOPE ON PERISTALTIC TRANSPORT OF COUPLE STRESS FLUIDS THROUGH A POROUS MEDIUM

Abstract

The peristaltic transport of couple stress fluid in a variable viscosity through the gap between coaxial tubes through a porous medium with magnetic field has been studied. Where outer tube is non-uniform sinusoidal wave traveling down in wall and inner tube is rigid. The relation between viscosity, pressure gradient and friction force on inner and outer tubes have been obtained in terms of couple stress parameter through a porous medium. The numerical solution of pressure gradient, outer friction, inner friction and flow rate are shown graphically.
