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 - ...
Introduction of rain gauges into monitoring of sewer systems: Experiences in choosing, testing and installing the measuring equipment / Uvođenje kišomera u sistem praćenja rada kanalizacionog sistema - iskustva iz faze nabavke, provere i postavljanja
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2005)
Improvement of the Belgrade sewer system performance, necessitated by increasing urbanization, calls for more precise assessment of water balance in the system. In this respect, three rain gauge stations are established ...
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 ...
