Controlled Latent Heat Phase-Change Microcapsules for Temperature Regulation
ACS Applied Materials & Interfaces, 2023Microencapsulation of phase-change materials (PCMs) is of great value and significance for improving energy efficiency and reducing carbon dioxide emissions. Here, highly controllable phase-change microcapsules (PCMCs) with hexadecane as the core material and polyurea as the shell material were developed for precise temperature regulation.

Modeling and impacts of the latent heat of phase change and specific heat for phase change materials
Applied Physics Letters, 2018We model the latent heats of crystallization and fusion in phase change materials with a unified latent heat of phase change, ensuring energy conservation by coupling the heat of phase change with amorphous and crystalline specific heats. We demonstrate the model with 2-D finite element simulations of Ge2Sb2Te5 and find that the heat of phase change ...

Latent heat storage through phase change materials
Resonance, 2015Energy requirement is increasing day-by-day for all of us. Though the major demand comes in the form of electrical energy for domestic as well as the industrial sector, some of this demand can be reduced by appropriately utilizing thermal energy available via solar radiation. Phase change material (commonly known as PCM), which has become an attractive

Latent Heat or Phase Change Thermal Energy Storage
1985It has been explained in sections 1.6 and 1.6.2 how phase change materials (PCM) have considerably higher thermal energy storage densities compared to sensible heat storage materials and are able to absorb or release large quantities of energy (“latent heat”) at a constant temperature by undergoing a change of phase.

Phase Change Characteristics of a Nanoemulsion as a Latent Heat Storage Material
International Journal of Thermophysics, 2013The primary objective of this study was to investigate the fundamental phase change characteristics of a nanoemulsion using differential scanning calorimetry (DSC). Tetradecane, which has a slightly higher melting point than water, was utilized as the phase change material for the nanoemulsion.

Latent heat storage system by using phase change materials and their application
Materials Today: Proceedings, 2022Abstract Due to the rapid exploitation of fossil fuels, energy sources are becoming nonrenewable, and there is a need to develop other technologies to provide a clean supply of energy. The heat is stored in the thermal storage unit utilizing phase change materials in one of two ways: sensible heat or latent heat.

NUMERICAL RESOLUTION OF A PHASE CHANGE PROBLEM WITH ZERO LATENT HEAT
Numerical Heat Transfer, Part B: Fundamentals, 1990Two numerical methods to simulate Ike behavior of a class offree-boundary thermal systems are presented and compared. The state of the system is governed by the conduction equation, where an isotherm defines the moving boundary for which a Neumann condition is considered. Unlike the classical Stefan problem, the moving boundary velocity does not appear

Solid/Liquid Phase Change Heat Transfer in Latent Heat Thermal Energy Storage
ASME 2009 3rd International Conference on Energy Sustainability, Volume 2, 2009Phase change materials (PCMs) have been widely used for thermal energy storage systems due to their capability of storing and releasing large amounts of energy with a small volume and a moderate temperature variation. Most PCMs suffer the common problem of low thermal conductivity, being around 0.2 and 0.5 for paraffin and inorganic salts, respectively,
