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) 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; ...
