    Frontiers in Heat and Mass Transfer, Vol.15, pp. 1-10, 2020, DOI:10.5098/hmt.15.10

    Abstract This study numerically investigates the charging and discharging processes of a three-stages cascaded latent heat thermal energy storage unit using three molten salts as the phase change materials (PCMs). Each stage of the unit is a vertical shell-and-tube heat exchanger, whose shell side is filled with the PCM and air. The liquid fractions, temperatures, and accumulated thermal energy of the PCMs during the fully charging and discharging processes, as well as the effects of the HTF inlet temperature, are analyzed. The results show that lower melting temperature of the PCM causes faster charging rate and more released heat in the… More >

    Comparative Study of Two Materials Combining a Standard Building Material with a PCM

    Marwa El Yassi1,2,*, Ikram El Abbassi1,2, Alexandre Pierre2, Yannick Melinge3

    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.5, pp. 1283-1290, 2023, DOI:10.32604/fdmp.2022.023183

    Abstract Phase change materials (PCMs) have the ability to store thermal energy and make it available at a later stage to keep indoor temperature within a specific range and achieve better thermal comfort in buildings. This study focuses on the performances of materials obtained by combining a standard building material with a PCM. In particular, two different materials mixed with the same PCM are considered under the same climatic conditions. The related thermal behavior is assessed in the framework of numerical simulations conducted with ANSYS Fluent assuming parameters representative of a city located in Europe.

    Numerical Investigation of the Thermal Behavior of a System with a Partition Wall Incorporating a Phase Change Material

    Nisrine Hanchi*, Hamid Hamza, Jawad Lahjomri, Khalid Zniber, Abdelaziz Oubarra

    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.5, pp. 1227-1236, 2023, DOI:10.32604/fdmp.2023.022530

    Abstract The work deals with the thermal behavior of a conventional partition wall incorporating a phase change material (PCM). The wall separates two environments with different thermal properties. The first one is conditioned, while the adjacent space is characterized by a temperature that changes sinusoidally in time. The effect of the PCM is assessed through a comparative analysis of the cases with and without PCM. The performances are evaluated in terms of dimensionless energy stored within the wall, comfort temperature and variations of these quantities as a function of the amount of PCM and its emplacement.

    Feriel Mustapha1,2,*, Marwa El Yassi1,2, Ikram El Abbassi1,2, Abdelhak Kaci2, Elhadj Kadri2, A-Moumen Darcherif3

    FDMP-Fluid Dynamics & Materials Processing, Vol.19, No.4, pp. 953-958, 2023, DOI:10.32604/fdmp.2022.022028

    Abstract A study is presented on the feasibility of an approach based on the combination of Phase Change Materials (PCM) with metal walls in container-type houses. This line of research finds its motivations in recent trends in the energy and building sectors about energy consumption reduction. Another important objective concerns possible improvements in the comfort provided by such houses during the summer period. The results obtained through numerical solution of the governing equations accounting for heat transfer and latent heat effects associated with the PCM show that the indoor temperature can be reduced with a varying degree of success depending on… More >

    Gang Wu1,2,*, Feng Liu1,2, Sijie Li1,2, Na Luo1,2, Zhiqiang Liu1,2, Yuqaing Li2,3

    Journal of Renewable Materials, Vol.11, No.2, pp. 707-730, 2023, DOI:10.32604/jrm.2022.022276

    Abstract The serpentine tube liquid cooling and composite PCM coupled cooling thermal management system is designed for 18650 cylindrical power batteries, with the maximum temperature and temperature difference of the power pack within the optimal temperature operating range as the target. The initial analysis of the battery pack at a 5C discharge rate, the influence of the single cell to cooling tube distance, the number of cooling tubes, inlet coolant temperature, the coolant flow rate, and other factors on the heat dissipation performance of the battery pack, initially determined a reasonable value for each design parameter. A control strategy is used… More >

    Simulation of the Hygrothermal Behavior of a Building Envelope Based on Phase Change Materials and a Bio-Based Concrete

    Dongxia Wu1, Mourad Rahim1, Wendong Li1, Mohammed El Ganaoui1,*, Rachid Bennacer2

    FDMP-Fluid Dynamics & Materials Processing, Vol.18, No.5, pp. 1483-1494, 2022, DOI:10.32604/fdmp.2022.021917

    Abstract Phase Change Materials (PCMs) have high thermal inertia, and hemp concrete (HC), a bio-based concrete, has strong hygroscopic behavior. In previous studies, PCM has been extensively combined with many materials, however, most of these studies focused on thermal properties while neglecting hygroscopic aspects. In this study, the two materials have been combined into a building envelope and the related hygrothermal properties have been studied. In particular, numerical studies have been performed to investigate the temperature and relative humidity behavior inside the HC, and the effect of adding PCM on the hygrothermal behavior of the HC. The results show that there… More >

    Abstract The fluctuation in drying temperature influences the food products’ quality and drying time significantly during the drying process using an indirect solar dryer. One of the effective methods to reduce these variations in the temperature is based on thermal storage materials to control the drying temperature. An experimental investigation is presented in this study to evaluate the performance of an indirect solar dryer with air double pass using multiple phase change materials (PCM) as thermal storage materials. Two PCMs with different melting points are used to store the available heat energy during peak sunshine periods and reduce the drying temperature… More >

    Caixia Wang2, Xiao Huang1,*, Hongqing Chen2, Weijie Liang2

    Journal of Renewable Materials, Vol.9, No.7, pp. 1239-1252, 2021, DOI:10.32604/jrm.2021.014746

    Abstract Currently, people pay more and more attention to the transitional resettlement of victims after various natural disasters. There is an urgent need for a large number of temporary houses to resettle the victims after natural disasters. Disaster-relief temporary houses (DTHs) played an important role in the post-disaster resettlement in the past, which can not only be produced on a large scale, but also can be quickly and conveniently erected, which were the main means to solve the problem of transitional resettlement. However, due to their temporary nature, there was no extra energy consuming system installed in the DTHs generally. Hence… More >

    Chanita Mano, Atthakorn Thongtha*

    Journal of Renewable Materials, Vol.9, No.3, pp. 495-506, 2021, DOI:10.32604/jrm.2021.013201

    Abstract This work focused on characterizing and improving the thermal behavior of metal sheet roofing. To decrease the heat transfer from the roof into a building, we investigated the efficiency of four types of phase change materials, with different melting points: PCM І, PCM II, PCM III and PCM IV, when used in conjunction with a sheet metal roof. The exterior metal roofing surface temperature was held constant at 50°C, 60°C, 70°C and 80°C, using a thermal source (halogen lights) for 360 min to investigate and compare the thermal performance of the metal sheet roofing with and without phase change materials… More >
