This study investigates the influence of Glycerin content, water-to-binder (w/b) ratio, and concrete grade on the thermal and mechanical properties of concrete incorporating Glycerin as a phase change material (PCM). M20, M30 and M40 grades of concrete were studied using 0.40, 0.45 and 0.50 w/b ratios. The amount of Glycerin varied from 0 %, 2.5 %, 5.0 %, 7.5 % to 10 % and compressive strength was studied on 7, 28, 56 and 90 days. The slump values decrease with increasing glycerin content, especially at higher w/b ratios, with M20 concrete exhibiting the lowest slump due to its lower grade. Maximum compressive strength is achieved at 5% glycerin content across all mix categories, with a w/b ratio of 0.45 yielding the highest strength. Glycerin content affects the thermal properties, while the w/b ratio significantly influences thermal conductivity. Glycerin content has the most significant impact on thermal diffusivity and specific heat capacity. The interaction between glycerin dose, w/b ratio, and concrete grade is analyzed using Response Surface Methodology (RSM), revealing complex dependencies among these factors. These findings contribute to understanding the behavior of glycerin-modified concrete and provide insights for optimizing its thermal and mechanical properties in construction applications.

In order to determine the ideal degree of inclination that should be employed for constructing effective thermal energy storage systems, it is important to examine the impact of inclination angle on the melting behavior of phase change materials (PCMs) such as paraffin wax within a square cell. In consequence, this would guarantee the greatest capacity for energy release and storage. Additionally, analyzing this influence aids engineers in creating systems that enhance heat flow from external sources to the PCM and vice versa. To find out how the cell’s inclination angle affects the melting of PCM of paraffin wax (RT42) inside a square cell, a numerical analysis is carried out using the ANSYS/FLUENT 16 software. Specifically, the temperature and velocity distributions, together with the evolution of the melting process, will be shown for various inclination angles, and a thorough comparison will be made to assess the influence of inclination angle on the PCM melting process and its completion. The findings demonstrated that when the cell’s inclination angle increased from 0° to 15° and from 0° to 30° and 45°, respectively, the amount of time required to finish the melting process increased by 15%, 42%, and 71%, respectively. Additionally, after 210 min of operation, the PCM’s maximum temperature is 351.5 K with a 0° angle of inclination (horizontal) against 332.5 K with an angle of inclination of 45°.

“…Since 2018, the field of heat transfer analysis for PCMs has been a dynamic and evolving area of research [8][9][10][11][12][13][14][15][16][17][18][19][20]. Computational methods and numerical simulations were widely used to analyse and predict the behaviour of PCMs under complex thermal conditions and facilitate the design and optimization of PCM-based systems.…”

Aligning the European Union goals for climate neutrality by 2050 and the ambition for carbon equivalent emissions reduction to almost half by 2030 demands the exploration of alternative decarbonisation pathways. Energy consumption across all sectors is identified as a crucial contributor to this challenge, with a number of legislative and regulatory frameworks and commitments to be introduced every year. In response to these trends, the concept of exploiting a building’s thermal mass through the integration of phase change materials (PCMs) enhances the ability of building elements to reserve and deliver large amounts of energy during phase transitions. However, the incorporation of PCMs into building elements requires the thorough understanding of their thermal behaviour. This study evaluates and predicts the thermophysical properties of mineral particles carrying PCMs and coated with a cementitious layer able to be utilised as fillers in construction applications. By employing deep learning and predictive modelling techniques, the numerical data-driven model developed in this paper enhances accuracy and efficiency in property estimation and prediction, facilitating material selection, system design, and optimisation. A model in a MATLAB simulation environment is presented, evaluating and predicting the thermophysical properties of semi-organic particles able to enhance building envelope thermal mass as a hybrid energy storage solution. These findings show the time needed for a building block to undergo cooling, demonstrating a clear upgrade in the thermal discharge of the walls. Substituting traditional EP with PCM-enhanced EP leads to a minimum reduction of 1 °C per hour in the discharge rate, thereby extending the comfort duration of indoor spaces without necessitating additional space heating. These models offer the potential for assessing diverse material compositions and usage scenarios, offering valuable insights to aid decisions in optimizing building energy efficiency.
