“…Except the advantages of metal and derivatives, the performances of metal/PCM SSPCMs could also be tuned by designing the shape and geometry of metal structure. [52,53] Coupled with the multiple function of metal matrix, the metalbased SSPCMs promises for great potentials in manufacturing advanced materials.…”

Organic phase change materials (OPCMs) are advanced energy storage materials with ability to storage and release thermal energy at constant temperature. Efficient energy storage systems using shape-stabilized PCMs (SSPCMs) are promising to adjust the gap between energy supply and demand. The performances of SSPCMs are influenced by multiple factors which are necessary to be considered in the fabrication process. In this regard, we summarized the desired properties for OPCMs and SSPCMs, then we systematically discussed the fabrication methods involving supporting materials, OPCMs and fillers. At last, we elaborated thermal storage applications of SSPCMs from three kinds of energy sources. This review intends to provide in-depth and constructive insights into the fabrication and energy storage applications of SSPCMs, thereby contributing to development and application of high-performance SSPCMs.

“…Furthermore, a porosity reduction leads to a system overall diffusivity increase, so determining a higher storage rate. Nie et al [4] employed the enthalpy-porosity model to perform a numerical study in LTNE assumption, in which both charging and discharging processes have been evaluated for three different shell and tube configurations of a TESS heated with water: cylindrical, with conical shell and with frustum tube (the last two with variable tilt angles). The simulations show that non-cylindrical geometries guarantee an enhanced natural convection (and a more efficient conductive transfer in the case of frustum tube), culminating in a higher melting rate.…”

A numerical investigation on Latent Heat Thermal Energy Storage System (LHTESS) based on an aluminum foam totally filled with phase change material (PCM) is accomplished. The PCM used is a pure paraffin wax with melting over a range of temperature and a high latent heat of fusion. The LHTESS geometry under investigation is a vertical shell and tube. The corrugated internal surface of the hollow cylinder is assumed at a constant temperature above the PCM melting temperature. The other external surfaces are assumed adiabatic. The paraffin wax phase change process is modelled with the enthalpy-porosity theory, while the metal foam is considered as a porous media obeying to the Darcy-Forchheimer law. Local thermal non-equilibrium (LTNE) model is assumed to analyze the heat transfer in the metal foam. The governing equations are solved employing the Ansys-Fluent code. The numerical simulations results, reported as a function of time, and concerning the LHTESS charging phase, are compared in terms of melting time, average temperature and energy storage rate. The corrugated internal surface effect is analyzed with respect to the wavelength and wave amplitude of the corrugation.

“…The authors suggested that PCM, cylinder radius, and the inlet temperature and mass flow of HTF can affect the performance of the storage and should be chosen carefully when optimizing the performance. Nie et al [13] studied the effect of geometry on the performance of the shell-and-tube latent thermal energy storages using pure PCM and composite PCM. The results revealed that the impact of geometry modification on the thermal performance is different with pure and composite PCMs.…”
