Instability analysis of the air-water flow in porous medium / Analiza pojave nestabilnosti kod dvofaznog strujanja u poroznoj sredini
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2010)
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 ...
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 ...
Analytical models of confluences: A survey and models' assessment / Pregled i ocena analitičkih modela ušća
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2011)
Assumptions upon which development of 1D models of free-surface flow rest are not valid at open-channel junctions. Thus, the 1D flow equations cannot be used for calculation of upstream flow depths, or water levels in a ...
Influence of boundary conditions on nonlinear response of laminated composite plates / Uticaj graničnih uslova na nelinearan odgovor laminatnih kompozitnih ploča
(Institut za istraživanja i projektovanja u privredi, Beograd, 2012)
In this paper the influence of different boundary conditions on geometrically nonlinear response of laminated composite plates is analyzed. Mathematical model, based on layer-wise displacement field of Reddy [1], is ...

Implementation of value engineering on residential projects / Primena vrednosnog inženjerstva na projektima izgradnje stambeno-poslovnih objekata
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2015)
For the purpose of further affirmation of value engineering (VE), this paper gives a contribution in developing procedures for the practical application of VE on residential projects. In accordance with the theoretical ...
Vertical track geometry deterioration modeling / Modeliranje propadanja vertikalne geometrije koloseka
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2010)
Deterioration of the track geometry of ballasted tracks is unavoidable. In order to foresee the deterioration of the track, the phenomena have to be understood and described in an engineering way. Through the years a lot ...
Marginal distributions of daily precipitation in Serbia / Marginalne raspodele kumulativnih dnevnih padavina na prostoru Srbije
