“…Shedding of PCM-solid-layers to enhance heat transfer for the discharge process was mostly achieved using active mechanical scrappers. 39,40 Studies to date do not exist on employing non-stick STFs for the temperature range up to $250 C. In mechanical scrapping, detaching the PCM-solid-layers from HX surfaces is typically accomplished using an electrical motor that provides shaft power for the scrapper. The total energy expended in shedding PCM-solid-layers includes the energy to overcome friction, and mechanical energy to drive the scrapper.…”

When discharging latent heat thermal energy storage (LHTES) systems, performance is influenced by the formation and adherence of a solid layer of phase change material (PCM) on heat eXchange (HX) surfaces. Super‐liquid‐repellent thin films (STFs) may be able to reduce solidifying PCM adhesion on HX surfaces during discharging, delay PCM solidification to lower temperatures, and by modifying nucleation sites potentially enable long‐term seasonal thermal storage. Techniques employed previously to fabricate sintered polymeric STF coatings include chemical vapour deposition, dip‐coating, spray‐coating, spin‐coating, layer‐by‐layer (LbL) assembly, sol‐gel, anodizing, electrodeposition, electrospinning, so on. Dip‐coating is considered attractive for fabricating thin films on simple and complex surface geometries due to process maturity, scalability, flexibility and cost‐effectiveness. To identify suitable materials for preparing STFs on metal HX surfaces using the dip‐coating process, more than 200 journal articles published in English during the period 2010 to 2022 were reviewed and the potential role of STFs in LHTES applications was assessed. The review identified key areas and applications stimulating STF material developments and formulations. The dip‐coating of potential STF materials was classified under three major themes driving current research and development (R&D) activities, that is, high performance thin films, eco‐friendly thin films and fundamental research formulations. This review provides a platform from which to develop coatings and HX systems to enable the cost‐effective implementation of STFs for improved heat transfer in future mobile/stationery LHTES systems.

“…Active heat transfer enhancement techniques employed with LHTES systems include mechanical aids, vibration, jet impingement, injection, and external fields. There have been great reviews on alternative techniques [20], heat transfer physics [21], and passive/active techniques [22]. The passive/active review mainly focuses on passive techniques and only covers active enhancement with external fields and vibration.…”

Renewable energy resources require energy storage techniques to curb problems with intermittency. One potential solution is the use of phase change materials (PCMs) in latent heat thermal energy storage (LHTES) systems. Despite the high energy storage density of PCMs, their thermal response rate is restricted by low thermal conductivity. The topic of heat transfer enhancement techniques for increasing thermal performance of LHTES systems has mainly focused on passive heat transfer enhancement techniques with less attention towards active methods. Active heat transfer enhancement techniques require external power supplied to the system. In this paper, recent advances in active heat transfer enhancement techniques within LHTES systems are reviewed, including mechanical aids, vibration, jet impingement, injection, and external fields. The pertinent findings related to the field are summarized in relation to the charging and discharging processes of PCMs. Suggestions for future research are proposed, and the importance of additional energy input for storage is discussed.

“…On the other hand, heat exchangers that can be used in non-clean environments are critical in recent applications. For example, the scale of geothermal utilization [8][9][10] and the solidified layer in latent heat storage (LHS) 5,6,[11][12][13][14] cover the heat exchange wall heat exchange wall and impede efficient heat transfer. The heat transfer rate decreases significantly due to the thermal resistance in the covered layer, as shown in Fig.…”

To establish a low-carbon society, it is necessary to break away from dependence on fossil fuels, and the utilization of geothermal energy/waste heat is one of the key methods. When using geothermal energy, the rate of heat transfer decreases with time due to the precipitation of scale on the heat transfer surface, and periodic maintenance is required. Therefore, the running cost of utilizing geothermal energy is high. We focused on a rotary heat exchanger consisting of a rotating cylinder as the heat transfer wall and a fixed blade attached to the rotating cylinder for scraping the heat transfer surface. In this study, the heat recovery characteristic from chloride hot spring was experimentally evaluated. The results showed that scale formation on the heat transfer surface could be suppressed and the heat transfer characteristics could be maintained for one month.
