20.500.12556/RUL-96750 Karakterizacija prehoda med tokovnimi režimi dvofaznega toka pri curku plina v prečni tok kapljevine Characterization of the two–phase flow regime transition at gas jet in liquid cross flow Zaključna naloga obravnava karakterizacijo prehoda med tokovnimi režimi dvofaznega toka pri curku plina v prečni tok kapljevine. Klasifikacija režimov dvofaznega toka je bila do sedaj v večini primerov izvedena zgolj na podlagi opazovanja in subjektivne presoje. Delo obravnava razvoj in aplikacijo nove metode, ki na podlogi digitalnega post procesiranja hitro tekočih videoposnetkov omogoča objektivno določanje režima dvofaznega toka. Osnova metode je primerjava strukturnih funkcij toka na treh lokacijah vzdolž kanala za posamezno kombinacijo pretokov. Razvoj in umerjanje metode sta bila opravljena s polovico opravljenih meritev, preostale pa so služile kot test in kontrola pravilnosti delovanja. Metoda se je v večini primerov izkazala za zanesljivo, saj je bil tokovni režim pravilno napovedan. The topic of this work is the characterization of two-phase flow regime transition at the gas jet in the liquid cross flow. The classification of the two-phase flow regimes has been thus far mostly carried out based on flow observation and subjective judgment. The work deals with the development and application of a new method, which enables objective determination of the two-phase flow regime based on digital post-processing of high-speed video recordings. The method compares the structural flow functions at three locations along the channel for each flowrate combination. The development and calibration of the method were carried out with half of the measurements made, while the rest was used as a test and control of method performance. The method proved to be reliable in most cases, as the appropriate regime was predicted. dvofazni tok curek plina v prečni tok kapljevine karakterizacija režimov toka two phase flow gas jet in liquid cross flow characterization of flow regimes true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-10-14 07:15:05 2017-10-14 07:15:09 2023-11-10 13:05:09 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 202082 1301.pdf 1301.pdf 1 16AABC056A081830D285511414810FF0 1bcab532cb3b5f8372918ae9e97a93845923f3852be2138401faaff4eb836a6c f8d011ed-a1b3-11eb-a523-00155dcfd717 20.500.12556/rul/fe578f35-3f9d-468e-8234-8a61584f540e https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=105505 Fakulteta za strojništvo 0 0 0
