The results showed that the TEHM system presents 20% and 7% more energy and exergy efficiency than the TECM systems. The best system concerning FWAP was the TEHM with PCM and turbulator, producing a value of 10.5 L/m2 day. While for the same system without PCM, the FWAP was 7.5 L/m2 day.
Phase-change material (PCM) refers to a material that absorbs or releases large latent heat by phase transition between different phases of the material itself (solid–solid phase or solid–liquid phase) at certain temperatures. 1–3 PCMs have high heat storage densities and melting enthalpies, which enable them to store relatively dense …

With the popularization and application of phase change energy storage technology, the problem of supercooling has attracted the attention of many scholars. It has proved to be the most economical and efficient method to eliminate or reduce the supercooling of materials by adding nucleating agents.
Abstract. Phase change materials (PCMs) primarily leverage latent heat during phase transformation processes to minimize material usage for thermal energy storage (TES) or thermal management applications (TMA). PCMs effectively serve as thermal capacitors that help to mitigate the imbalance between energy demand and …

In this paper, the mechanical and thermal properties of phase change energy storage concrete are reviewed, and the existing …
By melting and solidifying at the phase-change temperature (PCT), a PCM is capable of storing and releasing large amounts of energy compared to sensible heat storage. Heat is absorbed or released when the material changes from solid to liquid and vice versa or when the internal structure of the material changes; PCMs are accordingly referred to as latent …
Introduction. 50 years after the discovery of phase change memory (PCM) it makes sense a look that bundles together a retrospective gaze to rebuild its history, both from a technology and products development point of view, with the opportunities of PCM for new applications looking to the future. This review paper aims to merge these glances ...

Phase change materials absorb thermal energy as they melt, holding that energy until the material is again solidified. Better understanding the liquid state physics of this type of thermal storage may help accelerate technology development for the energy sector. "Modeling the physics of gases and solids is easier than liquids," said co ...

Abstract. Supercooling is a natural phenomenon that keeps a phase change material (PCM) in its liquid state at a temperature lower than its solidification temperature. In the field of thermal energy storage systems, entering in supercooled state is generally considered as a drawback, since it prevents the release of the latent heat.
