20.500.12556/RUL-92952 Analiza tlačnih izgub v prenosnikih toplote pasterizatorjev Analysis of pressure loss in heat exchanger in pasteurizers Delo obravnava tlačne izgube v prenosnikih toplote pasterizatorjev mleka. Za meritve tlačnih izgub smo zasnovali merilno verigo in, pri različnih pretokih vode, izmerili izgube na več različnih prenosnikih toplote. Naredili smo odtis oblike prenosnika toplote in izračunali njegov hidravlični premer. S pomočjo Reynoldsovega števila smo določili tokovne režime. Izdelali smo empirični model za izračune tlačnih izgub za različne prenosnike toplote, s pomočjo katerega lahko izberemo primerno črpalko. Rezultate smo medsebojno primerjali in ovrednotili. In the present thesis, analysis of pressure loss in heat exchangers in pasteurizers is presented. For measuring of the pressure losses, measurement system was conceived. Losses were measured on various heat exchangers at different water flow rates. Footprints of heat exchangers surfaces were made and hydraulic diameters were calculated. With calculated Reynolds numbers flow regimes were determined. Empirical model for the calculation of pressure losses was developed for easier selection of the suitable pump. Results were compared and evaluated. prenosnik toplote merilna veriga tlačne izgube karakteristika sistema hidravlični premer izbira črpalke empirični model mehanika fluidov heat exchanger measurement system pressure loss system curve hydraulic diameter pump selection empirical model fluid mechanics true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2017-07-11 09:22:26 2017-07-11 09:22:26 2022-08-10 01:22:36 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2018-06-26 189591 451.pdf 451.pdf 1 C3B9ABE36F628F4D28F8C16A3345EA18 45ff858959f260fe901b6ccdd170081b938ec4d9ef2db73921c72b59bde9f5ee 77435f76-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/475bc4e8-2f47-4587-8284-27029d0ffa37 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=101118 Fakulteta za strojništvo 0 0 0
