Convective melting of packed beds
TLDR
In this paper, the volume averaged equations for convective melting of particles in a packed bed are developed and a simple model is solved numerically in one dimension to predict melting rates for a single substance and a system in which the liquid phase at elevated temperature enters a packed ground of the solid phase at the melting temperature.About:

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.
