Peristaltic transport in a cylindrical tube through a porous medium

Abstract

The problem of peristaltic transport in a cylindrical tube through a porous medium has been investigated. A perturbation solution is obtained, which satisfies the momentum equation for the case in which the amplitude ratio is small. The results show that the fluid phase mean axial velocity increases with increasing the permeability parameter k . The phenomena of reflux is discussed. Numerical results are reported for various values of the physical parameter
