With a goal of wider usage of renewable energy sources that are clean and sustainable, effective technologies, such as thermal energy storage (TES), play a vital role in storing thermal energy for future use. In this study, silver nanoparticles were dispersed in paraffin wax, eicosane, as phase change material (PCM). Thermal conductivity was measured following the transient method, using a Thermal Constants Analyzer with transient plane source technique. Thermal conductivity ...
Passive cooling is a method of dissipating heat rejected by electronic devices, and when associated to a phase change can be very effective. Phase change materials (PCMs) are widely used for thermal storage applications due to their ability to store and release large amounts of energy. Paraffin waxes also exhibit desirable characteristics, such as high latent heat and low thermal conductivity. This article looks at four nano-PCMs, obtained by seeding ...
In this thesis study, the sensor was used to characterize polymer encapsulated paraffin waxes as phase change materials (PCM). The main purpose of this study was to determine the effect of the polystyrene (PS) and PS: wax microcapsules on the morphology and thermal, mechanical and conductivity properties of the polypropylene matrix. Post-melting, the PP microcapsules were extremely well dispersed within the matrix and there was a strong interaction between them ...
Al2O3, TiO2 nanoparticles, and carbon nanotubes were added to Iraqi paraffin wax in varying quantities to determine the optimum filler content for the enhancement of thermal conductivity. The thermal conductivity was enhanced by 65 and 40% for samples containing 5 wt. % of Al2O3 and TiO2 nanoparticles, respectively. It was concluded that the addition of these nanoparticles to paraffin wax enhanced the thermal conductivity of the phase change material without sacrificing its ...
