Oblikovanje ulaza u zaliv primenom modela ravanskog i prostornog tečenja / Designing a Bay Entrance With 2D and 3D Numerical Model
(Građevinski fakultet Univerziteta u Beogradu, 2006)
Najveći problem zaliva je zasipanje - prirodan proces koji se ne može izbeći. Visoki troškovi održavanja zaliva (bagerovanja mulja i čišćenja obala) nameću potrebu mera za smanjenje uvlačenja nanosa u zaliv. Budući da je ...
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 ...
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 ...
Assessment of the position and dimensions of the ski-jump scour-hole / Procena položaja i dimenzija erozione jame ski odskoka
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
This paper is concerned with the ski-jump design, mainly for the large overflow dams. Although the vast scope of literature on this subject exists, there is still a need to compile, elaborate and upgrade available knowledge. ...
Numerical simulation of concentrated release of dredged sediments into the river / Numerička simulacija koncentrisanog ispuštanja izbagerovanog nanosa u maticu reke
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2007)
This paper deals with prediction of hydraulic consequences of concentrated release of dredged sediments into the river using a two-dimensional numerical model. It is shown that flow, concentration, and siltation fields can ...
Streamflow measurement by salinity dilution method / Merenje protoka u otvorenim tokovima metodom razblaženja koncentracije soli
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
Streamflow measurement often requires a clearly structured measurement reach. Velocity distribution can then be measured using a current meter or by constructing a hydraulic section control (weirs or flumes). However, in ...
Application of 2D and 3D modelling in bay entrance design / Oblikovanje ulaza u zaliv primenom modela ravanskog i prostornog tečenja
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2007)
Bays suffer from siltation, which is a natural process that cannot be avoided. The main cause of this process is mixing of the river-water containing suspended sediment and the river-bay water. High costs of maintenance - ...
Instability analysis of the air-water flow in porous medium / Analiza pojave nestabilnosti kod dvofaznog strujanja u poroznoj sredini
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
The paper deals with modeling of two phase (water-air) flow in coarse porous medium, where, after reaching some air velocity, instability of the flow occurs. Firstly, a linear stability analysis has been conducted for ...
Field measurement of small velocities / Merenje malih brzina u terenskim uslovima
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2006)
The application of 2D and 3D Computational Fluid Dynamics (CFD) modeling in open river flow is gaining in its popularity, especially in the field of sediment deposition on the river confluences and bay entrances. The ...
2D modelling of water quality in bays / Modeliranje kvaliteta vode u zalivu primenom modela ravanskog tečenja
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2007)
Contamination of river waters in terms of scale, intensity, and duration cause such severe problems that application of conventional engineering methods for environmental remediation projects is no longer adequate, and ...
