Abstract: In this study, the problem of peristaltic flow through a porous medium is studied for the case of non-uniform channel. The problem is formulated and analyzed using a perturbation series of a wave number as a parameter. We obtained an explicit form for the velocity components and the pressure gradient to the second order. Moreover, the pressure rise and the average pressure rise are computed and are explained graphically. The results show that both pressure rise and average pressure rise decrease as permeability parameter k increases.
