Interaction of pulsatile flow on the peristaltic motion of couple stress fluid through porous medium in a flexible channel

Abstract

In this paper, we discuss the peristaltic and pulsatile flow of a couple stress fluid through porous medium in a channel bounded by flexible walls. The non-linear equations governing the flow through porous medium are solved under perturbation scheme. The flow separation, the formation of bolus and phenomenon of reflux and the velocity filed and the wall stress are investigated analytically and their behavior is discussed computationally. 2000 Mathematics Subject Classifications: 92C50,92C60,92C05,76S05
