20.500.12556/RUL-177850 Influence of layering and Curie temperature uncertainty on the performance of multilayer active magnetic regenerators Magnetic refrigeration is a promising alternative to traditional vapor compression systems, with potential efficiency and environmental sustainability advantages. However, the narrow operational temperature range of magnetocaloric materials (MCMs) and their reliance on rare-earth elements remain key challenges. Multilayer active magnetic regenerators (AMRs) address the temperature range limitations by combining multiple magnetocaloric layers, each with different Curie temperatures. This study investigates the impact of statistical deviations in Curie temperatures on the performance of multilayer AMRs, specifically using second-order La-Fe-Co-Si materials. A 1D multilayer AMR numerical model is developed to simulate the effects of Curie temperature variability, with radial basis function neural networks employed to efficiently predict performance. The results indicate that although increasing the number of MCM layers enhances cooling power and coefficient of performance (COP), Curie temperature uncertainties significantly degrade the AMR performance. The likelihood of achieving cooling targets diminishes as the number of MCM layers increases, particularly for standard deviations exceeding 1 K. These findings emphasize the importance of accounting for Curie temperature uncertainties in AMR design. Moreover, enhancing the manufacturing precision of the Curie temperatures of MCMs is essential for improving the performance and commercialization of magnetocaloric technology. active magnetic regenerator magnetocaloric properties Curie temperature neurual networks numerical modelling machine learning multilayers numerical models aktivni magnetni regenerator magnetokalorične lastnosti Curiejeva temperatura nevronske mreže numerični modeli true false true Angleški jezik Slovenski jezik Članek v reviji 2026-01-09 13:47:51 2026-01-09 13:47:56 2026-01-10 04:27:53 0000-00-00 00:00:00 2025 0 0 21 str. iss. 52, art. e24282 Vol. 35 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 537:536 1616-3028 10.1002/adfm.202424282 249789699 Adv_Funct_Materials_-_2025_-_Tomc_-_Influence_of_Layering_and_Curie_Temperature_Uncertainty_on_the_Performance_of.pdf Adv_Funct_Materials_-_2025_-_Tomc_-_Influence_of_Layering_and_Curie_Temperature_Uncertainty_on_the_Performance_of.pdf 1 B5BF9783FC0ECBB72ADE4686A813B712 e0184fed13d1577153c238422496a047ca6e05cf18c6b36a21b17e541ae83d07 b8de60d8-ed6a-11f0-bf92-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=225232 https://advanced.onlinelibrary.wiley.com/doi/10.1002/adfm.202424282 1 6998240d-ed59-11f0-bf92-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=225216 Fakulteta za strojništvo 0 0 0
