Transient Pulsating Flow in Channels Partially Filled with a Porous Material

ABSTRACT

Analytical solutions are obtained for (he problem of transient pulsating flow in parallel-plate channels partially filled with a porous material. The investigation considers three different cases: in the first case, one porous substrate is attached at one of the channel walls; in the second, one porous substrate is inserted at the center of the channel; and in the third, one porous substrate is inserted at each of the channel walls. Also, the effect of the local macroscopic inertial term in the porous domain momentum equation is investigated. It is found that this term has significant effects at large Darcy numbers and high frequency of oscillations.
