Energy loss in a circular-conduit bends with supercritical flow / Gubitak energije u krivini kružnog provodnika pri burnom tečenju
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2013)
In this paper the energy loss in a circular conduit bend with supercritical flow is analyzed. Based on the test results obtained by a scale model, the energy-loss coefficient has been determined. Simple empirical relationships ...
Supercritical flow in circular-conduit bends / Burno tečenje u krivini provodnika kružnog poprečnog preseka
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2013)
Complex flow pattern occurring in a circular conduit bend with supercritical flow is analyzed. The research was done by a scale (physical hydraulic) model, and a numerical model developed in ANSYS (Fluent) surrounding. The ...
Seismic hydrodynamic load analysis / Proračun seizmičkih hidrodinamičkih opterećenja
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
Zangar's method for computation of seismic hydrodynamic loads acting at the inclined contour of a concrete gravity dam, has been reconsidered. Several numerical models are compared with the procedure recommended by Zangar, ...
Methodology for sequent depth estimation for converging stepped-chute stilling basins / Metodologija proračuna spregnutih dubina kod umirujućih bazena neprizmatičnih stepenastih brzotoka
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2016)
The influence of converging stepped spillways on the dimensions of the stilling basins for RCC dams was examined, based on the results of physical modeling, existing empirical expressions, and basic laws of fluid mechanics ...
Flood control of tailings-dam reservoirs / Problemi evakuacije velikih voda iz jalovišnih akumulacija
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
This paper analyzes the problems of flood control for the tailings-dams reservoirs, having in mind the significant rise of the flow and volume of observed flood waves, and increasingly stringent criteria for safety of high ...
Hydraulic design of morning glory spillway with a deflector upstream of the vertical bend / Određivanje dimenzija šahtnog preliva empirijskim jednačinama
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2012)
Hydraulic design of shaft spillways (morning-glory spillways) with flow deflector before the vertical bend is considered. Based on the physical hydraulic model investigations of several structures and available experience ...
Stresses in the upstream cutoff zone of concrete gravity dams / Naponsko stanje u zoni uzvodnog zuba gravitacione betonske brane
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
Upstream cutoff in the concrete gravity dam foundation is introduced as a general stability measure in the beginning of the 20-th century. It become widely accepted in design practice in the late 50-ties. Nevertheless, ...
Estimating the capacity of double side-channel spillways / Procena propusne moći dvostrukog bočnog preliva
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2009)
A double side-channel spillway consists of two spillways, with channels joining into a common single branch, noting that for some specific site conditions such arrangements may suit better than the conventional one-side-channel ...
Rešavanje jednačina kretanja fluida metodom zasnovanom na praćenju fluidnih delića (SPH metoda) / SPH method
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2014)
U ovom radu se opisuje numerička metoda za rešavanje jednačina kretanja fluida zasnovana na praćenju fluidnih delića, koja se na engleskom jeziku naziva Smoothed Particle Hydrodynamics (skraćeno SPH). Predstavljene su ...
Possible use of hydropower potential of cooling water at the thermal power plant / Mogućnost korišćenja hidroenergetskog potencijala vode za hlađenje termoelektrana
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
Possibility of using hydropower potential of cooling water at the thermal power plant with open cooling system is presented in the paper. Cooling water flows gravitationally to the recipient - the river. In the periods of ...
