20.500.12556/RUL-134893 Ferrofluidic thermal switch in a magnetocaloric device Thermal switches are advanced heat-management devices that represent a new opportunity to improve the energy efficiency and power density of caloric devices. In this study we have developed a numerical model to analyze the operation and the performance of static thermal switches in caloric refrigeration. The investigation comprises a parametric analysis of a realistic ferrofluidic thermal switch in terms of the maximum temperature span, cooling power, and coefficient of performance. The highest achieved temperature span between the heat source and the heat sink was 1.12 K for a single embodiment, which could be further developed into a regenerative system to increase the temperature span. A sensitivity analysis is conducted to correlate the relationship between the input parameters and the results. We show that thermal switches can be used in caloric devices even when switching ratios are small, which greatly extends the possibilities to implement different types of thermal switches. thermal switches ferrofluids magnetic cooling heat transfer thermal management sensitivity analysis toplotna stikala ferofluidi magnetno hlajenje prenos toplote upravljanje s toploto občutljivostna analiza true false true Angleški jezik Slovenski jezik Članek v reviji 2022-02-10 12:08:59 2022-02-10 12:09:00 2023-11-29 09:31:22 0000-00-00 00:00:00 2022 0 0 15 str. iss. 2, art. 103779 Vol. 25 Feb. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 536:620.1/.2 2589-0042 10.1016/j.isci.2022.103779 96902659 RAZ_Klinar_Katja_2022.pdf RAZ_Klinar_Katja_2022.pdf 1 9CBFFB1C4BEFC54E73A713D6B056D56B c1e1f08955d3f1de2c20044a99070497a620e7c98a09231017f2df7f8a2cd14d 5275a5b6-8a63-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153625 https://www.sciencedirect.com/science/article/pii/S2589004222000499 1 9dd79f17-8a61-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=153624 Fakulteta za strojništvo 0 0 0
