dc.description.abstractThe increasing need for energy, along with limiting resources, has encouraged the development of novel solutions in the fields of energy conservation and storage. Phase change materials (PCMs), which are differentiated by properties such as large energy storage capacities, chemical stability, and reactivity to reduced working temperatures, play an important role in addressing the need for energy conservation. The goal of this research is to identify the heat transfer properties of various organic and inorganic phase change materials, compare their performance under certain working situations, and assure their maximum efficiency. The study undertakes a numerical analysis of the heat transfer performance of diverse organic (RT31, RT50) and inorganic (SP31, SP50) phase change materials across varying Reynolds numbers (Re = 500, 1000, 1500, 2000) under laminar conditions within a regenerative double-pipe heat exchanger. The outcomes reveal that SP31 demonstrates a 16% higher heat transfer effectiveness than RT31, while SP50 surpasses RT50 by 18% in terms of heat transfer effectiveness. As the Reynolds number increases, so does the heat transfer effectiveness, total heat transfer coefficient, and number of transfer units (NTU) for all types of phase change materials, but the capacity ratio decreases. Notably, inorganic phase change materials exhibit superior heat transfer performance compared to their organic counterparts. The results obtained from this study have been evaluated to be potentially useful for enhancing energy efficiency and system performance in systems operating at low-temperature ranges by utilizing phase change materials in heat exchangers under specified flow conditions.Please check the edit made in the article title.
