The initial analysis of the river Ibar temperature downstream of the lake Gazivode
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
As a result of a very limited number of geometric and other input data, the temperature modeling of the river Ibar downstream of the lake Gazivode was started by analyzing one river reach between Pridvorica, secondary dam ...
Remaining life assessment of a high pressure turbine casing in creep and low cycle service regime
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Thick walled components such as high pressure (HP) steam turbine casings operating under high parameter conditions are subjected to a complex stress state. As a result of that stress state, some parts of HP turbine casing ...
Influence of furnace tube shape on thermal strain of fire-tube boilers
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The aim of this paper is to use numerical analysis and fine element method-FEM to investigate the influence of furnace tube shape on the thermal strain of fire-tube boilers. Thermal stresses in corrugated furnace tubes of ...
Finite element modelling of creep process - steady state stresses and strains
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Finite element modelling of steady state creep process has been described. Using an analogy of visco-plastic problem with a described procedure, the finite element method has been used to calculate steady state stresses ...
Modeling of the buckstay system of membrane walls in watertube boiler construction
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Membrane walls are very important structural parts of water-tube boiler construction. Based on their specific geometry, one special type of finite element was defined to help model the global boiler construction. That is ...
Influence of hydrodynamic conditions and nozzle geometry on appearance of high submerged cavitating jets
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2013)
Based on visualization results of highly-submerged cavitating water jet obtained with digital camera, the influences of related parameters such as: injection pressure, nozzle diameter and geometry, nozzle mounting (for ...
Energy efficiency improvement by gear shifting optimization
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2013)
Many studies have proved that elements of driver’s behavior related to gear selection have considerable influence on the fuel consumption. Optimal gear shifting is a complex task, especially for inexperienced drivers. This ...
Thermal analysis of physical and chemical changes occuring during regeneration of activated carbon
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
High-temperature thermal process is a commercial way of regeneration of spent granular activated carbon. The paper presents results of thermal analysis conducted in order to examine high-temperature regeneration of spent ...
Numerical research of the compressible flow in a vortex tube using openfoam software
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
The work presented in this paper is dealing with numerical simulation of energy separation mechanism and flow phenomena within a Ranque-Hilsch vortex tube. Simulation of turbulent, compressible, highly swirling flow inside ...
Theoretical analysis of the cumulative costs of different diesel bus alternatives for a public transport in the city of Belgrade
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
This paper includes comparative analysis of the environmental, energetic, and financial costs of different bus propulsion, possibly applied on the public transport in the city of Belgrade. It considers the modern diesel ...
