Experimental measurements and a numerical simulations of the time development of the temperature field were performed. Due to the complexity of the problem the simulation had to be performed in two steps. The first step takes into consideration the whole furnace, while in the second step only a single ferite plate is analyzed. The experiment, the numerical model (the heat-transfer equation) and the generation of the discretized model of the furnace for the chosen computational domain e.g. furnaces with heaters plates, ferrites, bearers and supports, are described. The results of the numerical simulation are analyzed and compared with experimental data. The agreement between the numerical results and the experimental data was goodObravnavana je analiza prenosa toplote v postopku sintranja feritov v komorni peči. Izvedeni sta bili meritev in numerično simuliranje časovnega razvoja temperaturnega polja. Zaradi zahtevnosti problema je simuliranje potekalo v dveh delih. V prvem delu je obravnavana celotna peč, v drugem delu pa je analiziran samo pladenj s feriti. V prispevku je opisan postopek meritve temperature, numerični model(enačbe prenosa toplote) in generacija mrežastega modela peči za izbrano računsko območje, tj. notranjost peči z grelniki, pladnji, feriti, nosilci in podstavki. Narejena je analiza rezultatov numerične simulacije in njihova primerjava z izmerjenimi vrednostmi. Ujemanje numerične rešitve in izmerjenih vrednosti je dobraTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaUniverza v Ljubljani, Fakulteta za strojništvo
