In this study, potassium tetrahydrate is being considered as a strong thermal energy storage material. Potassium tetrahydrate possess a low melting temperature and displays a large specific and volumetric enthalpy of fusion; all properties desirable of a thermal energy storage material. At temperatures ranging from 243 to 348 K, both solid and liquid potassium tetrahydrate were tested. The results obtained were then compared to two other potential thermal energy storage materials, with ...
The ability of Cu-H2O nanofluids to perform as phase change materials (PCMs) is investigated. The supercooling behavior of the nanofluids was determined as a function of copper nanoparticle concentration. The contact angle and thermal conductivity of this PCM were also determined experimentally. Based on the experimental results, the authors conclude that these nanofluids could be useful in thermal energy storage applications....
A paraffin-based composite phase change material (PCM) was prepared by the addition of hexagonal boron nitride (h-BN) nanosheets to melted paraffin wax followed by vigorous stirring. The nanosheets were added in quantities ranging from 1 to 10 wt. %. A reference sample of pure paraffin was also prepared. It was determined that the addition of h-BN nanosheets resulted in an increase in thermal conductivity and that the melting and solidification rates were also ...
