Comparative analysis of the results obtained with 3d orthogonal and non-orthogonal grids in the 3d-flow models: Part 1 / Uporedna analiza rezultata dobijenih primenom ortogonalnih ineortogonalnih mreža u modelima prostornog tečenja - deo l
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
Application of orthogonal and non-orthogonal grids in numerical models of the three-dimensional flow is considered. A river confluence is chosen as an example due to strong three-dimensional flow effects occurring at the ...
SPH method / Rešavanje jednačina kretanja fluida metodom zasnovanom na praćenju fluidnih delića (SPH metoda)
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2014)
The SPH (Smoothed Particle Hydrodynamics) method for solving fluid dynamics equations is presented in this paper. The main aim of this paper is to present theoretical aspects of the method which is used in numerical modelling ...
Compiled free surface mathematical models uncertainty propagation / Propagacija neodređenosti kod linijskih modela otvorenih tokova
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
Free surface flow is usually simulated by 1D numerical models. This approach assumes flow simplification and requires model calibration in order to reproduce flow characteristics in a realistic way. The calibration and ...
Analiza srednjih voda u srbiji na osnovu digitalnih karata padavina i temperatura
(Vodoprivreda, 2018)
Increase of the effectiveness of the reservoirs during the flood control: On the example of Trebišnjica Hydrosystem / Povećanje efikasnosti upravljanja akumulacijama u periodu odbrane od poplava - na primeru Hidroenergetskog sistema na Trebišnjici
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2012)
As a consequence of the more extreme hydrological phenomena (increasing of high water and reduction of low water regimes and extension of their duration) water storage reservoirs get demanding requirements to be used for ...
Numerical simulation of hydraulic consequences of dam failures on coal-ash disposal sites / Numerička simulacija hidrauličkih posledica havarija brana na pepelištima
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2003)
The objectives of numerical simulation of hydraulic consequences of dam failure on coal-ash disposal sites are to define the scope of flooding consider possibility of early warning, and undertake the appropriate protective ...
Optimization of pressurized pipe networks modelled with ΔQ method / Optimizacija mreža pod pritiskom modeliranih ΔQ metodom
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2013)
Efficiency of optimization of water networks in terms of expenditure of computer running time depends on the speed of the hydraulic calculations. In this paper use of the ΔQ method for network calculation, was tested on ...
Problemi pri skretanju burnog toka - kosi stojeći talas / Problems of Direction Changes in Supercritical Flow - Oblique Standing Waves
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, 1997)
U radu se analizira buran tok vode sa slobodnom površinom i pojave do kojih dolazi usled naglog skretanja zida kanala. Ovakve nagle promene u burnom toku dovode do pojave kosih stojećih talasa.
Ovaj problem analizirao ...
Water supply systems modeling: Optimization of model parameters using PEST method / Modeliranje vodovodnih sistema - optimizacija parametara modela primenom PEST metode
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2004)
One of the reasons for discrepancy between results of the Water Supply Systems hydraulic simulation and measurement data is the uncertainty of values of mathematical model parameters. Because of that, the best possible ...
Improvement of the flow measuring methodology with the flat electromagnetic velocity probes / Unapređenje metodologije merenja protoka pomoću ravnih elektromagnetnih senzora brzine
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
One of the commonly used approaches, for the flow measurements in open chanel hydraulic systems, is to measure one depth and use the stable Q-H relationship to compute the flow rate. If this method is inappropriate, the ...
