“…Low TC of current commercial PCMs inhibits effective waste heat use. Soni et al conducted a numerical study using erythritol (sugar alcohol) for medium-temperature (100–150 °C) waste heat recovery applications . Various studies on the nontoxicity and stability of sugar alcohol PCMs concluded that erythritol is the most reliable for WHR at 100–150 °C temperature range compared to other sugar alcohols, − Cu, Al, TiO 2 , and SiO 2 nanoparticles were used as nanoadditives to improve PCM’s thermal properties.…”

Dispersion of nanoparticles is one of the potential solutions to improve the thermophysical properties of phase change (or transition) materials (PCMs) and enhance the performance of latent thermal energy storage (LTES) systems. The PCM ought to have a high latent heat of fusion, and zero or negligible coefficient of thermal expansion. A good PCM should have melting and solidification compatibility with negligible or zero subcooling, and it should not react with the common chemical reagents. The present known PCMs possess low thermal conductivity that results into a longer solidification and melting time of PCMs. In the past two decades, researchers have reported improved thermal conductivity and heat-storing capacity of PCMs employing graphite nanoparticles/fibers, carbon nanotubes/fibers, metal, and metal oxide nanoparticles. This work reviews the reported experimental and numerical studies describing the consequences of nanoparticle inclusions of various shapes and sizes on the thermal properties of the PCMs. This review attempts to make a consolidated database of the studies related to nanoadditive inclusion into PCMs for various applications. Graphene dispersed into PCM has resulted into 14 times thermal conductivity enhancement. As far as metal oxide nanoparticles are concerned, TiO2 and Al2O3 nanoparticles outperformed others. The compatibility between the nanoadditive and PCM is necessary to tailor favorable thermal properties. This work reviews numerous studies of different nanoparticle–PCM duos.

“…For improvement the erythritol thermal conductivity different additives were investigated such as expanded graphite [27], percolated aluminium filler [31], modified carbon nanotubes [28], vermiculate with graphite [32], spherical graphite [33], and nickel nanoparticles [33]. Researchers have also synthesized PCCs based on erythritol by addition of copper, aluminium, SiO2, and TiO2 nanoparticles individually, which led to significant improvements in the thermal conductivity [34]. However, all of the aforementioned additives require at least to some extent specialized chemical preparation and processing techniques, and hence a readily available additive will be less complex in the PCC synthesis as well as more economical.…”

Low thermal conductivity of organic phase change materials (PCMs) for thermal energy storage systems induces the necessity to apply suitable heat transfer enhancement techniques for these materials. The purpose of this study was to improve thermal conductivity of a PCM erythritol by using sodium chloride as an additive, such that the material can be applied for steam cooking systems when integrated with solar parabolic trough collectors. In this study, erythritol-NaCl composites were synthesized by using the melting method, and the key physicochemical properties of the composites were estimated by using differential scanning calorimetry (DSC) coupled with thermo-gravimetric analysis (TGA). The observations indicate that there has been a significant improvement in the thermal conductivity of erythritol supplemented with NaCl. Further, thermal behaviour of the material indicates that it is suitable for steam cooking applications. Furthermore, mathematical models based on the experimental observations can be potentially utilized for further studies of erythritol-NaCl composites.

“…1) Because of this characteristic, PCM plays an important role in energy conservation and emission reduction. 2,3) Up to now, PCM have showed great application potential in many fields, such as solar energy utilization, [4][5][6] intelligent building, [7][8][9] waste heat recovery, [10][11][12] thermal management [13][14][15] and so on. In particular, phase change materials have great application value in waste heat recovery.…”
