dc.description.abstract | In this paper a complex flow pattern occurring in a closed conduit bend with supercritical flow is analyzed. The research was done by a scale (physical hydraulic) model, and a numerical model developed in Ansys (Fluent) program surrounding. This article compares the results obtained by numerical and physical (scale) models, providing comments and recommendations for their application. Based on these results, simple empirical relationships were developed, describing the effects of the bend deflection angle and approach flow conditions (non dimensional depth and the Froude number upstream from the bend) on the considered flow. | en |
dc.description.abstract | U radu je analizirano složeno strujanje koje nastaje u krivini zatvorenog provodnika u burnom toku. Ispitivanja su urađena na hidrauličkom fizičkom modelu, ali i na numeričkom, formiranom u okviru programskog paketa Ansys (Fluent). Rezultati sa hidrauličkog modela su korišćeni za kalibraciju numeričkog, pa je u okviru rada prikazano poređenje rezultata dobijenih na pomenuta dva modela, sa komentarima i preporukama za njihovu primenu. Na osnovu izvršenih ispitivanja date su jednostavne zavisnosti kojima se opisuje uticaj veličine skretnog ugla i prilaznih uslova tečenja (dubina i Frudov broj uzvodno od krivine) na razmatrano tečenje. | sr |
