20.500.12556/DiRROS-21096 Simulation of temperature field in steel billets during reheating in pusher-type furnace by meshless method Using a meshless method, a simulation of steel billets in a pusher-type reheating furnace is carried out for the first time. The simulation represents an affordable way to replace the measurements. The heat transfer from the billets with convection and radiation is considered. Inside each of the billets, the heat diffusion equation is solved on a two-dimensional central slice of the billet. The diffusion equation is solved in a strong form by the Local Radial Basis Function Collocation Method (LRBFCM) with explicit time-stepping. The ray tracing procedure solves the radiation, where the view factors are computed with the Monte Carlo method. The changing number of billets in the furnace at the start and the end of the loading and unloading of the furnace is considered. A sensitivity study on billets' temperature evolution is performed as a function of a different number of rays used in the Monte Carlo method, different stopping times of the billets in the furnace, and different spacing between the billets. The temperature field simulation is also essential for automatically optimizing the furnace’s productivity, energy consumption, and the billet’s quality. For the first time, the LRBFCM is successfully demonstrated for solving such a complex industrial problem. pusher-type reheating furnace steel temperature field radiation convection diffusion strong form meshless method radial basis functions temperaturno polje jekla radiacija difuzija brezmrežne metode radialne bazne funkcije true false true MDPI Švica Angleški jezik Slovenski jezik © 2024 by the authors Neznano 2024-12-20 11:19:39 2024-12-20 11:19:40 2024-12-21 03:36:17 0000-00-00 00:00:00 2024 0 0 Nasl. z nasl. zaslona; Opis vira z dne 25. 4. 2024; str. 1-16 iss. 3, [article no.] 30 Vol. 29 Apr. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2024-04-24 536.7 2297-8747 10.3390/mca29030030 193881603 RAZ_Liu_Qingguo_2024.pdf RAZ_Liu_Qingguo_2024.pdf 1 E13D7E1A00049223976BCD40A21A4A99 4dde5cd87f48d01981c4c8a2e1487422d33e5e08dd0fd2d7c2e26e7558d7d7af 3e92935f-bebd-11ef-ba3f-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=29900 https://www.mdpi.com/2297-8747/29/3/30 1 ed5a110a-bebb-11ef-ba3f-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=29899 Inštitut za kovinske materiale in tehnologije 0 0 0
