20.500.12556/RUL-94860 Mehurčkasto vrenje čistih snovi Nucleate pool boiling of pure fluids V nalogi smo obravnavali določitev koeficienta toplotne prestopnosti pri mehurčkastem vrenju čistih snovi. Vrenje je eno najbolj učinkovitih in tehnično obvladljivih mehanizmov prenosa toplote. Izdelali smo primerjavo med sedmimi različnimi metodami določitve koeficienta toplotne prestopnosti pri mehurčkastem vrenju čistih snovi. V delu smo obravnavali mehurčkasto vrenje 57 različnih čistih snovi s 1126 izmerjenimi vrednostmi koeficientov toplotne prestopnosti pri mehurčkastem vrenju. Poleg analizirane reducirane tlačne odvisnosti smo vpeljali tudi reducirano temperaturno odvisnost koeficienta toplotne prestopnosti pri mehurčkastem vrenju. Pri tem reduciran tlak predstavlja kvocient tlaka nasičenja in kritičnega tlaka in reducirana temperatura predstavlja kvocient temperature nasičenja in kritične temperature. Izvedena analiza kaže obetavno možnost uporabe reducirane temperaturne funkcije za določitev koeficienta toplotne prestopnosti pri mehurčkastem vrenju. This work investigates the determination of heat transfer coefficient in nucleate pool boiling of pure fluids. Boiling is one of the most effective and technically manageable mechanisms of heat transfer. The comparison between seven different methods for determination of heat transfer coefficient in nucleate pool boiling of pure substances was made. This work investigates the nucleate pool boiling of 57 different pure fluids with 1126 measured values of the heat transfer coefficient. In addition to the analysed reduced pressure dependency we introduced the reduced temperature dependency of the heat transfer coefficient in nucleate pool boiling. The reduced pressure represents the quotient of saturation pressure and critical pressure, while reduced temperature represents the quotient of saturation temperature and critical temperature. The performed analysis shows promise in using reduced temperature to determine the heat transfer coefficient in nucleate pool boiling. prenos toplote mehurčkasto vrenje koeficient toplotne prestopnosti metode čiste snovi heat transfer pool boiling heat transfer coefficient methods pure fluids true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-09-08 12:17:45 2017-09-08 12:17:46 2022-08-10 02:00:08 0000-00-00 00:00:00 2017 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 199817 713.pdf 713.pdf 1 2DEA572FB09C8DD45A2DA7666644F332 41b647d95b670cc45556b6cc1f28114148e0df1b6888461b9e9016918a2d22a7 9d54c773-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/ae095b15-73be-42c6-b82d-23fdfea9e0fa https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=103310 Fakulteta za strojništvo 0 0 0
