Abstract

In this paper, we analyzed the transport phenomena in a porous medium subjected to a compressible oscillating flow by a capillary-tube model. It is found that momentum transport of a compressible oscillating flow in a capillary-tube follows the Darcy law and an expression for the permeability can be identified. In addition, a closed form analytical expression of the Nusselt number for solid-fluid interfacial heat transfer has been obtained by analyzing the energy equation.
