20.500.12556/RUL-162461 Latent thermal energy storage using solid-state phase transformation in caloric materials Materials with solid-to-solid phase transformations have considerable potential for use in thermal energy storage systems. While these materials generally have lower latent heat than materials with a solid-to-liquid phase transformation, their significantly higher thermal conductivity enables rapid thermal charging/discharging. Here, we show that this propertymakes them particularly promising for thermal energy storage applications requiring highly dynamic operation. A numerical analysis (using an experimentally validated numerical model) has revealed that some materials with solid-tosolid phase transformations offer an excellent capacity-power trade-off for thermal energy storage applications compared to the corresponding conventional phase change materials. While most conventional phase change materials generally offer higher thermal capacity due to larger latent heat, some metallic materials with solid-state transformation (e.g., Ni-Ti-based alloys, Mn-Co-Ga-B alloys) exhibit up to 10 times higher thermal output powers. These results highlight a significant potential of caloric solid-state materials to outperform traditional latent thermal storage systems for certain applications. thermal energy storage caloric materials solid state phase change materials numerical analysis solid-state transformation latent heat heat storage shranjevanje toplotne energije kalorični materiali trdno stanje materiali za fazno spremembo numerična analiza trdninska fazna transformacija latentna toplota hranilnik toplote true false true Angleški jezik Slovenski jezik Članek v reviji 2024-09-24 07:36:30 2024-09-24 07:36:36 2025-03-19 13:51:45 0000-00-00 00:00:00 2024 0 0 18 str. iss. 9, art. 102175 Vol. 5 Sep. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 536.7:519.61 2666-3864 10.1016/j.xcrp.2024.102175 206949635 Ahcin,_Kitanovski,_Tusek_-_Latent_thermal_energy_storage_using_solid-state_phase_transformation_in_caloric_materials_koncna.pdf Ahcin,_Kitanovski,_Tusek_-_Latent_thermal_energy_storage_using_solid-state_phase_transformation_in_caloric_materials_koncna.pdf 1 F2F7C0AA9E758F328D31704A5E3EBB12 d09ce04f9f328d3c63e5e90eac353de0e89ea70dd1e1c80073ce7e7ccad9220c 3a7b61e2-7a37-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=191792 https://www.sciencedirect.com/science/article/pii/S2666386424004600 1 d8e3be3d-7a36-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=191791 Fakulteta za strojništvo 0 0 0
