A Review – Study of the Thermo-Physical Properties of PCM with Dispersion of Nano Particles IJTSRD
In this article, a new sort of nanofluid phase change materials (PCMs) is developed by suspending a small amount of BeO nanoparticles in solution of wax. Its thermal conductivities, super cooling degree, latent heat, specific heat, and rheological behaviours of the nanofluids PCMs have investigated. A rectangular duct designed and numerical studies were performed to reveal the effects of molten PCM thermo physical properties on heat and exergy storage performance of latent heat storage (LHS) unit. The range analysis, regression analysis and optimization were conducted. The PCM selection criteria were established. The results show that for short time LHS system, the order of PCM properties effects on heat storage performance is melting temperature, thermal conductivity, specific heat, density and melting enthalpy successively. PCM with lower melting temperature, higher thermal conductivity and specific heat is beneficial to improve the heat storage rate and heat storage quality. For long time heat storage system, the order of PCM properties effects on heat storage performance is density, melting enthalpy, specific heat, melting temperature and thermal conductivity successively. PCM with higher density, melting enthalpy and specific heat can both improve the heat storage rate and heat storage quality.
