Discharge improvement of a phase change material‐air‐based thermal energy storage unit for space heating applications using metal foams in the air sides
TL;DR: In this paper , a phase-changing material (PCM) based air heat exchanger using a metal foam inside the heat transfer fluid (HTF) channel was examined, and the results showed that the presence of the porous medium in the system improved the discharging process by 116% compared with a nonporous medium system at the same flow rate.

Heat transfer enhancement through PCM thermal storage by use of copper fins
TL;DR: In this article, a cylinder-shaped thermal energy storage with radial rectangular copper fins was analyzed, and it was revealed that an increase of the ratio of heat transfer surfaces leads to the decrease of melting time and vice versa.

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.
