Principles of heat transfer in porous media
TL;DR: In this article, the authors identify the principles of transport in porous media and compare the available predicted results, based on theoretical treatments of various transport mechanisms, with the existing experimental results, and the theoretical treatment is based on the volume-averaging of the momentum and energy equations with the closure conditions necessary for obtaining solutions.

The method of volume averaging
TL;DR: In this article, a single-phase flow in homogeneous Porous Media is described. But the single phase flow is not a single phase of the Darcy's Law. But it is a phase of a single flow in a two-phase system.
