Numerical stability problems in hydrodynamic modelling of confluences with small junction angles
(Universidad de Concepción, 2009)
The paper addresses problems which arise from the use of 3D grids with quadrilateral faces on
the horizontal planes in hydrodynamic modelling of discordant beds asymmetrical confluences
with small junction angles. There ...
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 ...
Analytical optimization method for water supply systems modeling / Analitička optimizaciona metoda u modeliranju vodovodnih sistema
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2007)
The consequence of an uncertainty of water supply systems models’ parameters is the discrepancy between simulation results and measurement data. The best values of parameters that can be obtained from available measurement ...
Water losses reduction by managing operational pressure / Upravljanje radnim pritiskom u cilju smanjenja gubitaka
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2007)
Managing operational pressure is essential for effective reduction of water losses, so system operation is directed towards its maximum reduction with fulfilling the demand of each customer. With this objective, the variable ...
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 ...
Drainage of bridge decks in urban environment / Odvodnjavanje mostova u urbanim sredinama
(Savez građevinskih inženjera Srbije, Beograd, 2009)
Storm water drainage from buildings, motorways, airports or bridges is a complex task for design engineers. Bridge design deals not only with structural aspects, but with driving safety during heavy rainfall as well. To ...
Measurements in Belgrade sewer system / Merenja na Beogradskom kanalizacionom sistemu
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
The installation of monitoring system at 8 sewer outlets of Belgrade Sewer System has started during 2007. In this paper the extension of that process is presented, where 5 new monitoring sites were equipped and new ...
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 ...
