Numeričko određivanje radijacionih svojstava plamena ugljenog praha / Numerical determination of the pulverized coal flame radiative properties
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd i Društvo termičara Srbije, Beograd, 2013)
Ispitan je uticaj broja čestica letećeg pepela koje nastaju fragmentacijom jedne čestice koksnog ostatka na radijaciona svojstva disperzne faze plamena ugljenog praha, kao i da li se primenom tako dobijenih radijacionih ...
Numeričko i analitičko određivanje performansi vetroturbina sa vertikalnom osom obrtanja / Numerical and analytical investigation of vertical axis wind turbine
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2013)
Većina istraživanja vezanih za vetroturbine su fokusirana na precizno određivanje njihove efikasnosti. U radu je istaknut napredak koji je ostvaren u razvoju aerodinamičkih modela za analizu vetroturbina sa vertikalnom ...
Experimental stress-strain analysis of composite beams
(Croatian Society of Mechanics, 2013)
Assessment of the effect of pitting corrosion on fatigue crack initiation in hydro turbine shaft
(Trans Tech Publications Ltd, 2013)
Energy efficiency is a key issue worldwide, and not confined solely to the realm of engineers. Past failures of mechanical power system components must be examined carefully in order to minimise future occurrences and ...
Possibilities for reconstruction of existing steam boilers for the purpose of using exhaust gases from 14 MW or 17 MW gas turbine
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
Within the energy system in Methanol vinegar complex (MVC) in Kikinda, beside process boiler and auxiliary equipment, there are three equal steam boilers made by "Minel Kotlogradnja", provided for combustion of natural ...
Distortion of the substructure of a 20-ft shipping container exposed to zinc hot-dip galvanizing
(Institute of Metals and Technology, 2013)
The main goal of this study was to build a model for a numerical simulation of hot-dip galvanizing of a 20-ft ISO shipping container. For that purpose, the basic transient thermo-mechanical problem of a steel structure ...

Effect of austempering temperature on cavitation behaviour of unalloyed ADI material
(Elsevier Science Inc, New York, 2013)
This paper provides an in-depth study and description of cavitation damage and microstructural changes in two types of unalloyed austempered ductile iron (ADI). ADI materials used were austempered at 300 and 400 degrees C ...
Numerical Analysis of Thermal Conditions for Planning and Further Improvements of Hard Surfacing Experiment
(Amer Inst Physics, Melville, 2013)
An initial goal of this study was to use the results from an existing experiment and to set up as complete as possible the numerical model for the thermal analysis of a hard surfacing process. It was clear from the start ...
Architectural aspect of structural glass roof design
(CRC Press/Balkema, 2013)
The objective of the work is to study some solutions of the design and construction of structural glass roofs. Attractive glazed roofs could be achieved by enlarging the range and size of the glass panels, or by reducing ...
