20.500.12556/RUL-126365 Water surface topology of supercritical junction flow The complexity of flow conditions at junctions amplifies significantly with supercritical flow. It is a pronounced three-dimensional two-phased flow phenomenon, where standing waves with non-stationary water surface are formed. To analyse the hydrodynamic conditions at an asymmetric right-angled junction with incoming supercritical flows at Froude numbers between 2 and 12, an experimental approach was used. For a phenomenological determination of the relations between the integral parameters of incoming flows and the characteristics of standing waves at the junction area, water surface topographies for 168 scenarios at the junction were measured using non-intrusive measurement techniques. The new, phenomenologically derived equations allow for determination of location, height and extent of the main standing waves at the junction. Research results give important information on the processes and their magnitude for engineering applications. junction hydraulic experimentation standing wave supercritical flow flow patterns gradbeništvo vodarstvo hidrotehnika sotočje hidravlične raziskave stoječe valovanje deroči tok vzorci vodnega toka true false true Angleški jezik Slovenski jezik Članek v reviji 2021-04-19 11:54:10 2021-04-19 11:54:18 2022-09-05 03:54:55 0000-00-00 00:00:00 2019 0 0 Str. 163-170 iss. 2 Vol. 67 Jun. 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.22-821:626/627 0042-790X 10.2478/johh-2018-0042 8671841 RAZ_Rak_Gasper_2019.pdf RAZ_Rak_Gasper_2019.pdf 1 AB0923521ED66D4B8AB7FF823FC46732 3758ec77788f8578c7676c712fb7a84cad333519493b3087f90c61ab69263289 e50dd218-a1bb-11eb-a523-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=142288 https://www.sciendo.com/article/10.2478/johh-2018-0042 1 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=142287 Fakulteta za strojništvo 0 0 0
