“…6, respectively. Consistent with many studies conducted regarding the melting process of PCMs [6, [11][12][13], the heat transfer rate peaks during the early stages of melting due to the more considerable temperature difference between the PCM and HTF. During the initial stages of melting (t < 1000 seconds), conduction acts as the dominant factor since the temperature of most of the PCM is under the melting point (0℃) and hence still remains in solid form.…”

This study investigates the melting mechanics in a longitudinally finned multi-tube latent heat thermal energy storage system using water as the phase change material (PCM). Experiments on the melting performance of multiple arrangements of heat transfer fluid (HTF) tubes (HTF) are conducted and compared. The heat exchanger used for the study consists of a cuboid shell with inner dimensions of 210 x 80 x 110mm (depth x width x height) and a 3 x 2 in-line horizontal bundle. An ethylene glycol-water mixture (35% wt.) with an inlet temperature of 15℃ and a total flow rate of 2 LPM flows inside evenly through the selected tube to melt the PCM with an initial temperature of -5℃. Only four to six tubes are heated at a time. The results show that the position of heated tubes plays a significant role in determining the time required for complete melting due to thermal stratification caused by natural convection. In general, the heat transfer performance tends to increase when both HTF tubes at the bottom role are activated.

“…Furthermore, further research will explore the combination of the multitube structure with other measures mentioned above to enhance heat transfer. For example, Kiribcic , conducted a study on the melting and solidification process of a shell-and-tube phase change heat storage device equipped with straight fins. They developed an accurate descriptive model of the heat storage and release processes and conducted comparative calculations using Fluent software.…”

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.

“…After integrating the annular fins, the charging time of the heat storage was shortened by 65% and the discharging time was shortened by 58%. Kirincic et al [26] investigated the effect of longitudinal fins on the thermal performance of a latent heat storage. After installing longitudinal fins, the total melting time and solidification time of the heat storage was reduced by 52% and 43% respectively.…”
