The disparity between the supply and demand for thermal energy has encouraged scientists to develop effective thermal energy storage (TES) technologies. In this regard, hybrid nano‐enhanced phase‐change materials (HNePCMs) are integrated into a square enclosure for TES system analysis. Several HNePCMs are formulated with different highly conductive nanoparticles in varying proportions. For the numerical study, three HNePCMs, namely HNePCM‐1, HNePCM‐2, and HNePCM‐3, are employed to investigate melting characteristics and energy‐storage capacity analysis. The outcomes of the analysis are determined by examining several variables, such as mass fraction, enthalpy, and temperature, concerning the melting and heat‐transfer processes. In the results, it is indicated that HNePCM‐1_10% yields the best thermal performance as compared to the other HNePCM_8% and HNePCM_5% case studies. Furthermore, the melting time is shortened for HNePCM‐1_10%, HNePCM‐2_10%, and HNePCM‐3_10% by 20%, 10%, and 5%, respectively. The enthalpy of HNePCM‐1 exhibits greater enhancement compared to HNePCM‐2 and HNePCM‐3, respectively. The enhancement in energy‐storage capacity for HNePCM‐1_10%, HNePCM‐2_10%, and HNePCM‐3_10% is 18.69%, 16.66%, and 6.85% higher than that of the base material. Thus, HNePCMs are demonstrated to be more efficient materials and are emerging as potential materials to augment the performance of TES applications.

In comparison with sensible heat storage devices, phase change thermal storage devices have advantages such as high heat storage density, low heat dissipation loss, and good cyclic performance, which have great potential for solving the problem of temporal and spatial imbalances in the transfer and utilization of heat energy. However, there are also issues such as the small thermal conductivity of phase change materials (PCMs) and poor efficiency in heat storage and release, and in recent years, enhanced heat transfer in phase change thermal storage devices has become one of the research hotspots for optimizing thermal storage devices. Although there have been reviews of enhanced heat transfer technology for phase change thermal storage devices in the literature, there is still insufficient research on the summarization of the enhanced heat transfer mechanism, structural optimization, and applications of phase change thermal storage devices. This Review provides a review of enhanced heat transfer in phase change thermal storage devices from two aspects: internal structure enhanced heat transfer and heat exchange medium flow channel enhanced heat transfer. It summarizes the enhanced heat transfer measures of various types of phase change thermal storage devices and discusses the role of structural parameters in enhanced heat transfer. It is hoped that this Review will provide some references for scholars engaged in research on phase change thermal storage heat exchangers.

Many strategies have been attempted for accomplishing the needed changes in the heat-transfer rate in closed cavities in recent years. Some strategies used include the addition of flexible or hard partitions to the cavities (to split them into various pieces), thickening the borders, providing fins to the cavities, or altering the forms or cavity angles. Each of these methods may be used to increase or decrease heat transmission. Many computational and experimental investigations of heat transport in various cavity shapes have been conducted. The majority of studies focused on improving the thermal efficiency of heat transmission in various cavity containers. This paper introduced a review of experimental, numerical, and analytical studies related to heat transfer analyses in different geometries, such as circular, cylindrical, hexagonal, and rectangular cavities. Results of the evaluated studies indicate that the fin design increased heat transmission and sped up the melting time of the PCM; the optimal wind incidence angle for the maximum loss of combined convective heat depends on the tilt angle of the cavity and wind speed. The Nusselt number graphs behave differently when decreasing the Richardson number. Comparatively, the natural heat transfer process dominates at Ri = 10, but lid motion is absent at Ri = 1. For a given Ri and Pr, the cavity without a block performed better than the cavity with a square or circular block. The heat transfer coefficient at the heating sources has been established as a performance indicator. Hot source fins improve heat transmission and reduce gallium melting time.
