Peristaltic flow through a porous medium in a tube

الملخص EN

The paper investigates the peristaltic flow of an incompressible Newtonian fluid through a porous medium in axisymetric cylindrical tube.

A perturbation series (to first order) in dimensionless wave number of an infinite harmonic travelling wave is used to obtain an explicit form for the velocity and the pressure gradient.

Also, we discuss the effect of permeability parameter on both pressure rise and friction force.

The numerical results show that the pressure rise increases as the permeability decreases.
