“…Otherwise, solidification begins subsequently the temperature decreases well below the phase change temperature. It can be concluded that the simulation predicted the melting/solidification temperature of the PCM system and it is in good agreement with the literature [10,12,13]. Additionally, the model is taking all heat transfers that present a significantly improvement in melting time and the stored energy.…”

“…As a result, a comparison has been made which showed the possibility of a modelling that explains the behaviour of materials, which largely corresponds to the references [10,11], with a significant improvement in the current results, by dint of taking into account all heat transfer as an extra thermal energy.…”

“…Later on, the stored energy decreases when the temperature of the PCM decreases after use or the temperature of the environment decreases, which causes a decrease in the temperature in the system. The effect of heat flow on charging process has been studied in many previous literatures [10,12]. Some authors have mentioned that heat flow has a significant influence on the charging process.…”

The production and storage of thermal energy are important processes that contribute to the satisfaction of daily needs. They are effective ways of managing the thermal energy available from various solar applications. The most efficient storage technique is the use of phase change materials (PCMs) because these components can keep large amounts of thermal energy in stock. The problem is that this approach continues to be confronted with difficulties despite significant progress in research, design and modelling. Nevertheless, these difficulties can be resolved through numerical simulations that enable the identification of powerful tools for optimising thermal system design and predicting thermal behaviour. Correspondingly, in this work, thermo-mechanical modelling was conducted to describe the different methods of heat transfer that can optimise thermal energy storage via PCMs. This study also established a numeric resolution and the spatio-temporal discretisation of the basic equations accompanying the numerical model. The proposed numerical solution improves the prediction of thermal behaviour and can be used as a guide in designing new systems capable of producing and storing solar energy.

“…There have been numerous investigations over enhancement of their thermal conductivity, such as dispersion of inclusion of metallic objects. The incorporation of metal foams such as aluminum foam, 12 copper foam, 13 aluminum, 14 etc, besides metal oxide nanoparticle dispersion such as TiO 2 , 15 CuO, 16,17 zinc oxide, 18 SiO 2 , 19 etc. improves their thermal conductivity of the PCMs.…”

The present study focused on the preparation of form-stable composites of 1-tetradecanoic acid (TDA)/titanium dioxide (TiO 2) powder via a facile impregnation method. The use of powdered TiO 2 as porous material and thermal conductivity enhancer for TDA is a novel attempt. The morphological, chemical, and crystalline properties of form-stable composite PCMs (Fs-CPCMs), containing different amounts of TiO 2 , were characterized using field emission scanning electron microscope, Fourier transform infrared spectroscopy, and X-ray diffraction techniques. The finding supports that the produced composites were chemically and structurally stable. The latent heat storage (LHS) properties of composites were obtained from differential scanning calorimeter instrument, and the findings revealed that the Fs-CPCM with 50 mass% TDA has a melting temperature of 52.04 C and a considerably good LHS capacity of 97.75 J/g. The thermal conductivity of TDA was increased remarkably by the addition of TiO 2 micro particles. The results obtained from thermogravimetric analysis and thermal cycling test exhibited that the Fs-CPCM, containing 50 mass% TiO 2 , possesses great thermal degradation durability, cycling chemical stability, and thermal reliability. This composite PCM can be very well used for passive thermal management of electronic devices, automotive components, photovoltaic thermal hybrid designs, solar air/water heating systems, etc.

When focusing on materials science in civil engineering, the current trend is to investigate the use of innovative solutions in order to enhance thermal and energy performances. This trend is amplified with the need for a sustainable development strategy for the construction sector. This paper assesses the integration of a Phase Change Material (PCM) in cement intended for building construction. The key characteristic of PCMs is their capacity to absorb energy and restore it. In building construction, this feature could be harnessed to save energy by incorporating PCMs in the materials used. In this study, passive integration of PCM in cement was tested and thermal properties of such an integration was assessed. The results provide insights into how PCMs affect cement as part of the concrete mixture, thus identifying the contribution of PCM-based cements in concrete mixtures.
