“…At present, many researchers pay more attention to the improvement of thermal conductivity and supercooling suppression. − However, while solving the above problems (add additives), the corresponding heat storage capacity will decrease. − How to further improve the packaging performance is of great significance to the energy storage application of composite PCMs. In recent years, pore minerals have been studied extensively, and expanded vermiculite (EVM) has become a typical representative material with its unique layered pore structure, high porosity, and large pore volume.…”

In this study, the optimized expanded vermiculite (EVM) was used as the matrix and a series of novel form-stable composite phase change materials (fs-CPCMs) were prepared by the physical impregnation method. The results showed that acid leaching and organic intercalation EVM had a better package effect (≥74.9 wt %) and heat storage capacity (≥139.2 J/g) compared with EVM, which showed a good optimization effect, revealing that proper modification treatment was beneficial to the improvement of the thermophysical properties of composite PCMs. Nonisothermal crystallization kinetics demonstrated that the EVM matrix was beneficial to reduce the nucleation activation energy (ΔE a) of PEG, and the optimized EVM could further reduce the ΔE a, which effectively improved the crystal nucleation process of PEG. However, the matrix would restrict the crystal growth process of PEG, which had certain adverse effects. Moreover, XRD, TGA, and cycle tests showed that the prepared novel fs-CPCMs had excellent chemical stability, thermal stability, and cycle reliability. This research provided a certain theoretical reference and technical support for the preparation of mineral-based organic composite phase change materials with high heat storage capacity and excellent phase change behavior.

“…The increase of the heat transfer rate of PMC base LHTES is a hot topic that demands further research. Some of the possible approaches for improving the heat transfer are geometrical enhancement by enhancing the shape of PCM container [ 8 , 9 ] or tube placement [ 9 ], invoking extended surfaces and fins [ 10 , 11 ], heatpipes [ 12 , 13 ], metal foams [ 14 , 15 ], and nanoadditives [ 16 , 17 ].…”

A latent heat thermal energy storage (LHTES) unit can store a notable amount of heat in a compact volume. However, the charging time could be tediously long due to weak heat transfer. Thus, an improvement of heat transfer and a reduction in charging time is an essential task. The present research aims to improve the thermal charging of a conical shell-tube LHTES unit by optimizing the shell-shape and fin-inclination angle in the presence of nanoadditives. The governing equations for the natural convection heat transfer and phase change heat transfer are written as partial differential equations. The finite element method is applied to solve the equations numerically. The Taguchi optimization approach is then invoked to optimize the fin-inclination angle, shell aspect ratio, and the type and volume fraction of nanoparticles. The results showed that the shell-aspect ratio and fin inclination angle are the most important design parameters influencing the charging time. The charging time could be changed by 40% by variation of design parameters. Interestingly a conical shell with a small radius at the bottom and a large radius at the top (small aspect ratio) is the best shell design. However, a too-small aspect ratio could entrap the liquid-PCM between fins and increase the charging time. An optimum volume fraction of 4% is found for nanoparticle concentration.
