A review of materials, heat transfer and phase change problem formulation for latent heat thermal energy storage systems (LHTESS)
TL;DR: In this paper, the phase change problem has been formulated using pure conduction approach but the problem has moved to a different level of complexity with added convection in the melt being accounted for, which makes it difficult for comparison to be made to assess the suitability of PCMs to particular applications.

Experimental and numerical investigation of thermal energy storage with a finned tube
TL;DR: In this article, the phase change material (PCM) is used to fill the annular shell space around the finned tube while the heat transfer fluid flows within the tube, and the effect of each variable on energy storage and amount of solidification are investigated numerically and experimentally.

Numerical solution of phase-change problems
TL;DR: A three-time level implicit scheme, which is unconditionally stable and convergent, is employed for the numerical solution of phase change problems, on the basis of an analytical approach consisting in the approximation of the latent heat effect by a large heat capacity over a small temperature range as discussed by the authors.

Analysis of melting in the presence of natural convection in the melt region
TL;DR: In this article, an analysis of multidimensional melting is performed which takes account of natural convection induced by temperature differences in the liquid melt, and the results differ decisively from those corresponding to a conventional pure-conduction model of the melting problem.
