“…In this context, PCM can store or release a large amount of heat during the phase change process and are widely preferred in these systems (Lewis et al , 2004). Applications of PCMs have many including buildings (Kalbasi et al , 2023; Li et al , 2022), refrigeration (Bista et al , 2018; Schalbart et al , 2015) and thermal management of solar (Stalin et al , 2021; Venkatesan et al , 2022) and electronics systems (Mozafari et al , 2021; Nirwan et al , 2022). Despite having many benefits, most PCMs have a low thermal conductivity problem.…”

Purpose The purpose of this study is to examine the effects of inclination angle on the thermal energy storage capability of a phase change material (PCM) within a disc-shaped container. Different container materials are also tested such as plexiglass and aluminium. This study aims to assess the energy storage capacity, melting behaviour and temperature distributions of PCM with a specific melting range (22°C–26°C) for various governing parameters such as inclination angles, aspect ratios (AR) and temperature differences (ΔT) and compare the melting behaviour and energy storage performance of PCM in aluminium containers to those in plexiglass containers. Design/methodology/approach A finite volume approach was adopted to evaluate the thermal energy storage capability of PCMs. Five inclination angles ranging from 0° to 180° were considered and the energy storage capacity. Also, the melting behaviour of the PCM and temperature distributions of the container with different materials were tested. Two different AR and ΔT values were chosen as parameters to analyse for their effects on the melting performance of the PCM. Conjugate heat transfer problem is solved to see the effects of conduction mode of heat transfer. Findings The results of the study indicate that as AR decreases, the effect of the inclination angles on the energy storage capacity of the PCM decreases. For lower ΔT, the difference between the maximum and minimum stored energies was 20.88% for AR = 0.20, whereas it was 6.85% for AR = 0.15. Furthermore, under the same conditions, the PCM stored 8.02% more energy in plexiglass containers than in aluminium containers. Originality/value This study contributes to the understanding of the influence of inclination angle, container material, AR and ΔT on the thermal energy storage capabilities of PCM in a novel designed container. The findings highlight the importance of AR in mitigating the effect of the inclination angle on energy storage capacity. Additionally, comparing aluminium and plexiglass containers provides insights into the effect of container material on the melting behaviour and energy storage properties of PCM.

The global demand of the heating and cooling applications gives a larger potential to study the thermal energy storage system. Phase change materials (PCM) that are used to charge, store, and discharge the heat energy are inferior in heat transfer characteristics. The properties of PCM can be improved by adding nanoparticles, changing the orientation of the enclosure or both. Two-dimensional transient numerical analysis on the effect of Grashoff number (5000, 13000, and 20000), nanoparticle type (Al2O3, CuO, and MWCNT), and volume concentration (0%, 1%, 3%, and 5%) added in RT 42 PCM and orientation of square enclosure (30, 45, and 60°) to enhance the heat transfer rate is carried out. The thermophysical properties of the nano-PCM are evaluated and presented. From the results, it is affirmed that the melt fraction of the PCM rises with the increase in Gr and volume concentration of the nanoparticles up to an optimum level. The MWCNT-based nano-PCM attained a larger portion of melt fraction followed by Al2O3, CuO, and pure PCM. It is noted that an orientation of 60° and 45° will convert more quantities of pure PCM and nano-PCM into liquid fraction, respectively. The (3% MWCNT/RT-42 PCM) filled in 45° oriented container attained the highest melt fraction by 3.4%, 2.04%, and 2.94% than (3% Al2O3/RT-42 PCM), (1%CuO/RT-42 PCM), and pure PCM. The variation in the maximum melt fraction of the nanomaterial is because of the change in thermophysical characteristics of the nano-PCM.

The demand for thermal comfort by increased population results in growing energy consumption worldwide, resulting in deterioration of the global climate caused by greenhouse gas emissions. The latent heat storage technique is efficient because it can be operated at a minimum range of temperature. Especially, Phase change materials (PCMs), which have a tendency for solid-liquid phase transformation, have become a topic of great research interest. Organic PCM may be utilized in many thermal storage system applications. But none of the organic PCM in its pure form possesses all of the required properties for usage in real applications. So, to use a particular PCM in a variety of applications, eutectic PCM may be designed. The thermal characteristics like phase transition temperature and enthalpy of fusion may easily be adjusted by adding at least two PCMs to prepare eutectics with a lower melting temperature and higher energy density than either of the individual PCMs. The optimal composition of PCMs in the eutectic material and the lowest melting point are computed using the Schroder-Van Laar model. Also, because of the poor heat conduction of eutectic PCM, it puts a barrier to utilization in real-world applications. Various materials can be added in order to optimize thermal conductivity of these eutectic PCMs. Therefore, eutectic PCMs have the potential to be utilized for low-temperature heat energy storage practical applications and will progressively be included in worldwide heat management solutions in the coming years, and their price should indicate that they are worth the investment.
