A phase-change material (PCM) is a substance which releases/absorbs sufficient energy at phase transition to provide useful heat or cooling. Generally the transition will be from one of the first two fundamental states of matter - solid and liquid - to the other. The phase transition may also be between non-classical states of matter, such as ...
A cold-energy battery utilizes the properties of an advanced phase-change material (PCM) to maintain temperature as battery thermal management. As with a standard electrical battery, a cold energy battery stores energy and releases depending on the energy demand on it. It can then be recharged by placing in a temperature environment conducive ...
Recent research on PCM has been directed towards attempting to find viable material alternatives to the phase-change material Ge 2 Sb 2 Te 5 (GST), with mixed success. Other research has focused on the development of a Ge Te – Sb 2 Te 3 superlattice to achieve non-thermal phase changes by changing the co-ordination state of the germanium ...
A phase-change is the melting, solidifying, vaporizing or liquifying. Such a material is called a phase change material (PCM). Materials used in LHTESs often have a high latent heat so that at their specific temperature, the phase change absorbs a large amount of energy, much more than sensible heat. [39]
Peltier cooling plates / ˈ p ɛ l t i. eɪ / take advantage of the Peltier effect to create a heat flux between the junction of two different conductors of electricity by applying an electric current. [9] This effect is commonly used for cooling electronic components and small instruments.

Computational Fluid Dynamics (CFD) modeling and simulation for phase change materials (PCMs) is a technique used to analyze the performance and behavior of PCMs. The CFD models have been successful in studying and analyzing the air quality, natural ventilation and stratified ventilation, air flow initiated by buoyancy forces and temperature space for the systems integrated with PCMs.
