We study computationally the absorption of a passive solute through the walls of an oscillating channel of finite length. The channel is filled with an incompressible fluid which carries the solute. The channel walls pulsate in a prescribed manner and these pulsations generate a fluid flow that modifies the solute transference to the medium that surrounds the channel, and consumes solute at a constant rate. The fluid motion is governed by the incompressible Navier-Stokes equations and no-slip conditions at the solid-liquid interface. We apply our numerical results to a two dimensional model of a surgical technique used for treating patients with coronary artery disease.
