Microencapsulation of Fatty Acid as Phase Change Material for Latent Heat Storage
Journal of Energy Engineering, 2011Latent heat storage systems can improve the energy use efficiency and conserve limited energy resources. Microcapsules of lauric acid (LA) as the core and melamineformaldehyde (MF) resin as the shell were prepared as phase change material for latent heat thermal storage by in situ polymerization.

High Latent Heat and Recyclable Phase-Change Materials for Photothermoelectric Conversion
ACS Applied Materials & InterfacesRealizing organic phase-change material networks with excellent recyclability while maintaining high latent heat still faces great challenges due to the difficult trade-off between network composition. Herein, the high latent heat and recyclable phase-change materials (RPCMs) were developed by integrating linear poly(ethylene glycol) (PEG) multimers as

A latent-heat-coupled wellbore heat-transfer model with phase-change materials
Physics of FluidsDeep and ultra-deep resource development is increasingly constrained by extreme downhole temperatures, which compromise drilling safety, tool integrity, and drilling-fluid performance. Conventional cooling measures—including drilling-parameter optimization, adjustment of drilling-fluid properties, surface cooling, and improved drillstring insulation ...

Latent heat of fusion prediction for nanofluid based phase change material
Applied Thermal Engineering, 2018Abstract This paper presents a study on the effect of mass fraction of nanoparticles, cooling rates and prediction of latent heat of fusion for Barium Chloride Dehydrate solutions (BaCl2·2H2O) by separately adding a mass fraction of 0.2 wt%–1 wt% magnesium oxide (MgO) and multi-walled carbon nanotubes (MWCNTs) and various cooling rates applied.

Optimum Efficiencies and Phase Change Temperatures in Latent Heat Storage Systems
Journal of Energy Resources Technology, 1994This paper presents an analysis of a class of latent heat storage systems (LHSS). The analysis is based on a lumped model (the basic model) that allows a broad class of LHSSs to be completely specified, with only two parameters and a set of operating temperatures, while still retaining the main thermodynamic aspects associated with its operation ...

The effects of phase change during the stand-by period in latent heat energy storage systems
Solar Energy, 1991Abstract When the boundary condition causing a phase change is interrupted, the phase change process continues until the temperature distribution in the whole system becomes uniform due to the temperature gradients existing in both phases. This continuing phase change during the so called “stand-by solidification” period should be taken into ...

Development of paraffin wax as phase change material based latent heat storage in heat exchanger
Applied Thermal Engineering, 2019Abstract Energy storage mechanisms enhance the energy efficiency of systems by decreasing the difference between source and demand. For this reason, phase change materials are particularly attractive because of their ability to provide high energy storage density at a constant temperature (latent heat) that corresponds to the temperature of the phase

Modeling and optimization of phase change material composites for latent heat storage
2016The concept of low carbon, energy saving and sustainable design has been widely accepted all over the world. To increase the energy utilization efficiency, organic phase change materials (PCMs), which can store and release heat through phase change, have been recognized as an excellent candidate.
