dc.description.abstract | This paper deals with flow modelling of the stepped spillway for the Bogovina dam. The analysis was conducted using three approaches: scalemodelling, empirical equations and numerical modelling. An acceptable agreement was achieved between the empirical equations and the numerical model results, while both of them exhibit considerable differences when compared to scale-model. These discrepancies can be contributed to the difficulties in modelling the process of air-entrainment. Since air-entrainment is important for providing good estimates, existing empirical equations as well as numerical models require further improvements. | en |
dc.description.abstract | Tema rada je modeliranje strujnog polja na stepenastom brzotoku brane Bogovina. Analiza je sprovedena na rezultatima dobijenih pomoću: fizičkog modela, empirijskih jednačina i numeričkog modela. Slaganja rezultata empirijskih jednačina i numeričkog modela su u prihvatljivim granicama, dok je primećeno njihovo značajno odstupanje od rezultata merenja na fizičkom modelu. Uzrok ovih razlika je proces samo-aeracije mlaza. Budući da je ovaj proces važan za ovaj vid strujanja, nepohodno je poboljšati postojeće empirijske zavisnosti i numeričke modele. | sr |
