TL;DR: In this article, the solidification behavior of water-based nanofluid phase change material encapsulated in a spherical container was presented. And the authors predicted that there is a possible energy saving potential of approximately 6-9% in the thermal energy storage (CTES) system using the NFPCMs.
Abstract: This present study presents the solidification behavior of water based nanofluid phase change material encapsulated in a spherical container. The nanofluid phase change material (NFPCM) was prepared by dispersing the multi wall carbon nanotubes (MWCNT) with volume fractions of 0.15%, 0.3%, 0.45%, and 0.6% in de-ionized (DI) water as the base phase change material. The solidification experiments were conducted with DI water and the NFPCM and maximum reductions of 14% and 20.1% were observed in the solidification time with the NFPCMs at surrounding bath temperature of −9 °C and −12 °C respectively. The presence of MWCNT also acted as nucleating agent that caused appreciable reduction in the subcooling. The enhanced thermal transport properties of the NFPCM are very useful to operate the cool thermal energy storage (CTES) system at higher operating temperature of the secondary refrigerant. It is predicted that there is a possible energy saving potential of approximately 6–9% in the CTES using the NFPCMs.
