Phase change materials (PCMs) are becoming increasingly important in the field of thermal energy storage. In this study, conductive fillers were added to wax- and polyethylene-based PCMs to improve their thermal conductivity. A Thermal Constants Analyser measured the thermal conductivity of the PCMs using the transient plane source (TPS) method. Results indicated that both nanoparticles improved thermal conductivity, but a lower concentration of expanded graphite improved conductivity more than normal ...
Nanoparticle-enhanced phase change materials (NePCMs) are nanofluids that can be used for thermal energy storage when they undergo solid-liquid phase transitions. In this study, a Thermal Constants Analyzer (TPS) measured the thermal conductivity of eicosane-based NePCM samples using the transient plane source (TPS) method. Results showed that thermal conductivity of the solid composites increased with temperature, and eicosane-CuO samples that solidified in an ice-water bath had the lowest thermal conductivities, ...
Phase change materials (PCMs) can be used as heat sinks to manage high temperature fluctuations in electronics. In this paper, a heat sink was generated from a paraffin/expanded graphite composite PCM, and the thermal conductivities of the materials were measured using the transient plane source (TPS) method of the Thermal Analyzer. Results showed that the composite PCM had a significantly higher thermal conductivity than the pure paraffin....
Phase change materials (PCMs) store large amounts of latent heat over small temperature ranges, so their application in the thermal regulation of buildings is becoming more popular. However, PCMs have low thermal conductivities, so micro-encapsulated PCMs (micro-PCMs) are being incorporated into PCMs to enhance their performance and improve thermal conductivity. In this study, micro-PCMs were mixed with thermally conductive, inorganic gypsum powder and glass fiber to produce gypsum boards. The ...
A nanoparticle-enhanced phase change material (NePCM) is prepared by the dispersal of carbon nanotubes in 1-dodecanol. The objective of this experiment was to determine if the addition of nanoparticles could increase the thermal conductivity of the base PCM while resulting in a NePCM that would still have the required properties of a functional PCM. It was found that the thermal conductivity was enhanced through the addition of the carbon nanotubes; ...
