Abstract

The present paper investigates the peristaltic motion with porous medium though coaxial vertical channel: A theoretical study. A perturbation method of solution is obtained in terms of wall slope parameter and closed form of expressions has been derived for axial velocity pressure gradient and pressure rise. The effects of various physical parameters on axial velocity pressure gradient and pressure rise have been computed numerically. It is noted axial velocity increases with increases in Porous parameter (D) for the two cases   = - 0.5,   = -1 and also we noted that pressure rise decreases with increase in Porous parameter (D) and phase shipt (θ).
