Moving boundary problem: heat conduction in the solid phase of a phase-change material during melting driven by natural convection in the liquid
TL;DR: In this article, the authors present an analysis of the melting process in a rectangular enclosure, driven by the coupling of heat conduction in the solid phase and natural convection in the melt of the phase change material (PCM).
