Numerical modelling of supercritical flow in circular conduit bends using SPH method
(China Ocean Press, 2017)
The capability of the smoothed-particle hydrodynamics (SPH) method to model supercritical flow in circular pipe bends is considered. The standard SPH method, which makes use of dynamic boundary particles (DBP), ...
Pregled i ocena analitičkih modela ušća / Analytical models of confluences: a survey and models’ assessment
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2011)
Na spojevima otvorenih tokova strujnice postaju zakrivljene, jer vertikalno ubrzanje fluidnih delića nije zanemarljivo u odnosu na ubrzanje zemljine teže, pa su to mesta gde ne važe osnovne pretpostavke na kojima se zasnivaju ...
Flood flow frequency analysis in the presence of outliers / Statistička analiza velikih voda u prisustvu izuzetaka
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2016)
Flood flow frequency analysis is performed on the series of hydrological observations. The observations introduce uncertainties in the analysis results, inherited from limited data sets, operational difficulties in high ...
Application of artificial neural networks for hydrological modelling in karst
(Union of Croatian Civil Engineers and Technicians, 2018)
The possibility of short-term water flow forecasting in a karst region is presented in this paper. Four state-of-the-art machine learning algorithms are used for the one day ahead forecasting: multi-layer perceptron neural ...
Modelling the Drina river basin water resources system and analysis of selected development and climate scenarios / Modeliranje vodoprivrednog sistema sliva Drine i analiza izabranih razvojnih i klimatskih scenarija
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
The paper presents the methodological framework for the analysis of the Drina River basin water resources system under different development and climate scenarios. Within this methodological framework, a water management ...
Flow measurement at the short structures in hydraulic complex conditions: HE 'Djerdap 2' case study / Merenje protoka na kratkim objektima u hidraulički neregularnim uslovima na primeru HE 'Đerdap 2'
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
Hydraulic conditions at short structures in most cases prevents the existence of cross sections with parallel streamlines and fully developed turbulent flow profile. In such conditions the flow measurement is rather ...
Hydro energy potential of cooling water at the thermal power plant
(Elsevier Ltd, 2011)
The hydro energy of the gravity water flow from the coal-fired thermal power plant units to the river in an open cooling system of turbine condensers is determined. On the basis of statistical data for a long time period, ...
A Device for the Simultaneous Determination of the Water Retention Properties and the Hydraulic Conductivity Function of an Unsaturated Coarse Material; Application to a Green-Roof Volcanic Substrate
(ASTM CompassASTM International (American Society For Testing and Materials), 2019)
The determination of the water retention curve (WRC) and hydraulic conductivity function (HCF) of a specific volcanic coarse granular material used as a substrate for urban green roofs in Europe was carried out on a newly ...
Primeri primene ravnih elektromagnetnih sondi za merenje protoka u kolektorima / Examples of flat EM sensor application for flow measurements in collectors
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2019)
Merenje protoka u kolektorima sa otvorenim tokom, kao i kanalizacionim sistemima predstavlja izazov jer ne postoji jedna najbolja metoda, već je neophodno dobro poznavati radne uslove i shodno njima izabrati optimalnu mernu ...
Novi pristup pri određivanju pouzdanosti složenih vodoprivrednih sistema / New Method for Complex Water Resources Systems Reliability Evaluation
(Savez građevinskih inženjera Srbije, 2011)
U radu je prikazan nov pristup pri određivanju pouzdanosti složenih vodoprivrednih sistema pod pritiskom. Ovaj pristup podrazumeva da se pored pouzdanosti mehaničkih karakteristika elemenata, uzima u obzir i pouzdanost ...
