“…Gao et al [ 36 ] conducted subjective experiments on thermal manikins and real humans with PCM cooling undershirts and investigated that personal cooling using PCM reduced torso skin temperature by approximately 2–3 °C, achieving improved thermal comfort in simulated office work at 34 °C. The heat exchange rate of PCM depends on the temperature gradient, mass, and coverage area [ 43 ]. In the study of Li et al [ 33 ], the thermal comfort before and after wearing the phase-change cooling clothing in different scenarios were tested.…”

“…While the utilization of organic phase change materials (PCMs) is prevalent in many applications for low-temperature heat storage due to their large storage density [4], their low thermal conductivity often compromises the temperature control of thermal management facilities [5]. One solution is the use of PCM composites filled with nano-fillers [6] [7].…”

The effects of embedding fixed and movable metal foams in composite PCMs on the transient performance were studied with pulsed heat loads experimentally under various powers and different cell sizes. Similar conclusions could be drawn both from the experimental and numerical results. It was shown that when fixed metal foams were solely adopted, the heat storage system performance could be enhanced by ∼24.6% by increasing the number of metal foams by three times at the heat flux of 56.1 W/cm2 and 15 ppi. When the movable technique was utilized, the heat transfer enhancement reached up to 36.9% under the same amount of metal foams for the same cell sizes and heat flux. The better performances were attributed to combined positive influences due to the adoption of the movable metal foam technique, which extends heat transfer area, improves heat conduction, and eases suppression of natural heat convection by cutting the amount of metal foams. Moreover, as cutting the amount of metal foams could obviously reduce the wastage of energy storage capacity, the movable metal foam technique demonstrated quite a promising future.

“…Fins in H-shaped thermal storage cavities boost melting rate while charging phase change material, according to Izadi et al [18]. Fan Spiral fins raise the average Nusselt number by 28.6%, heat transfer rate by 20.9%-58.2% in charging and discharging, and heat flux by 17.5%-53.8% in shell-tube latent heat storage units according to Heet et al [19]. Zhang et al [20] quantitatively researched phase change material melting in finned thermal energy storage and found that integrating the double helical fin into the PCM area increases vertical latent heat storage performance.…”

The current work looks at a horizontally oriented double-pipe thermal energy storage system with PCM filled in the annular gap and heat transfer fluid (Water, MXene, and Al2O3 nanofluid) flowing in an inner tube from a physical standpoint. The discharging properties of a latent heat-based thermal energy storage system at various intake temperatures (290K, 298K, and 303K) have been analyzed while maintaining a constant mass flow rate of the heat transfer fluid.With varying input fluid temperatures, the numerical investigation of the influence of solidification on the liquid fraction and temperature for capric acid PCM-based thermal energy storage has been made. Based on the data, the TES system with 1% v/v. MXene nanofluid at 290K inlet temperature solidify capric PCM faster than water and Al2O3 nanofluid. In the TES system, PCM was solidified by water, MXene, and Al2O3 nanofluid as HTF in 30–120 minutes, 50–200 minutes, and 90–380 minutes, respectively, at an inlet temperature of 290K, 298K, and 303K. At a 290K inlet temperature, Al2O3 nanofluid solidified 90% PCM at 303.37K, 42.37% at 309.57K, and 68.35% at 306.27K. MXene nanofluid solidified PCM 90% during 90 minutes, 42.37%, and 68.35% after 30 and 60 minutes at 290K. Thus, MXene nanofluids as heat transfer fluids in double tube latent heat thermal energy storage are more feasible and valuable than traditional fluids for energy-efficient and sustainable thermal energy storage.
