Nenjutnovski fluidi u inzenjerskoj praksi
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije, 2011)
U procesnoj industriji (naftnoj, hemijskoj, prehrambenoj...) često je neophodno tretirati fluide koji se ne ponašaju kao idealni (njutnovski) fluidi. S obzirom da je kod takvih fluida (nenjutnovskih) odnos između intenziteta ...
Estimate of a power distributor life span based on the fracture mechanics criteria
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2011)
Dimensioning of pressure vessels can be done according to various criteria, the basic one being the safety against the fracture by splashing. In this paper two methods for this dimensioning procedure are presented. The ...
3-D model of solid and gas phase flow in the duct bend behind the mill gas classifier at the fan mill
(Nis University, 2011)
This paper shows the computer simulation of two-phase flow of the mill gases, the solid particles of monodisperse coal dust and the transport fluid. Numeric simulation was performed with the software pack Fluent 6.3.26, ...
Experimental analysis of fatigue fracture behaviour of Ti-6Al-4V alloys

Reconstruction of the aero-mixture channels of the pulverized coal plant of the 100 MW power plant unit
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
After the last revitalization of thermal power block of 100 MW in TPP 'Kostolac A', made in the year 2004, during the operation of the plant, pulverized coal deposition often occurred in horizontal sections of the aero-mixture ...
The effect of bowl-in-piston geometry layout on fluid flow pattern
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
In this paper some results concerning the evolution of 3-D fluid flow pattern through all four strokes in combustion chambers with entirely different bowl-in-piston geometry layouts ranging from 'omega' to 'simple cylinder' ...
The possibilities for measurement and characterization of diesel engine fine particles: A review
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
This review paper considers possible instrumentation for diesel engine fine particles exhaust emission evaluation. The modern diesel engines have extremely low particles emission almost at the level of measurement error ...
Using Open Standards Based Building Information Modelling to Simulate Actual Design and Construction Processes

The paper describes pilot project conducted to achieve first understanding of the IFC standard and BIM process in Serbia. During the project a research team have developed information model of the actual building using IFC ...
Surface characterisation of Pb1-XMnXTe alloy by atomic force microscopy and magnetic force mode
(MANEY PUBLISHING, LEEDS, 2011)
In this paper the authors present the results of surface characterisation of a lead telluride alloy conducted by atomic force microscopy and magnetic force microscopy. Relationship between surface morphology, in the range ...
Pregled eksplicitnih aproksimacija Kolbrukove jednačine za koeficijent trenja / A review of explicit approximations of Colebrook's equation
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2011)
U radu je dat pregled najčešće korišćenih eksplicitnih jednačina za određivanje koeficijenta trenja u glatkim i hrapavim cevima. Odstupanje navedenih jednačina od Kolbrukove jednačine izraženo je preko srednje relativne ...
