Experimental and numerical study of temperature field during hard-facing of different carbon steels
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
In this research the 3-D transient non-linear thermal analysis of the hard-facing process was performed by using the experimental testing and finite element method. Testing was done at three different carbon steels and the ...
Turbulence recognition in free convective flow by thermal-video post-processing in the case of a thermal power plant mill
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2021)
This paper presents a study of a free convection flow around the walls of a ventilation mill of the Thermal Power Plant "Kostolac B", Kostolac, Serbia. A combined method consists of thermography and software post-processing, ...
Influence of temperature on behavior of the interfacial crack between the two layers
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2010)
In this paper is considered a problem of the semi-infinite crack at the interface between the two elastic isotropic layers in conditions of the environmental temperature change. The energy release rate needed for the crack ...
Assessment results of fluid-structure interaction numerical simulation using fuzzy logic
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
A fuzzy approximation concept is applied in order to predict results of coupled computational structure mechanics and computational fluid dynamics while solving a problem of steady incompressible gas flow through thermally ...
Heat transfer enhancement through pcm thermal storage by use of copper fins
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
Enhancement of heat transfer over a cylinder shaped thermal energy storage filled by paraffin E53 by use of longitudinal rectangular copper fins was analyzed. The thermo-physical features of the storage material are ...
Analysis of the estimated remaining service life of gas rectification columns
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2021)
Gas rectification columns are process apparatuses which are very important part of each onshore plant. Sudden failure of these types of columns causes huge daily losses, while fluid leakage can be very dangerous for the ...
Application of Composite Construction and Demolition Debris in Heavy Metals Removal from Industrial Wastewater
(Thermal Science, 2023)
The utilization of construction and demolition debris in industrial wastewater treatment by sorption of Co2+ and Ni2+ ions was investigated. Selected waste composites are cost-effective and locally available, still their ...
Numerical study of transient three-dimensional heat conduction problem with a moving heat source
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
A numerical study of transient three-dimensional heat conduction problem with a moving source is presented. For numerical solution Douglas-Gunn alternating direction implicit method is applied and for the moving heat source ...
Rectified ethanol production cost analysis
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
This paper deals with the impact of the most important factors of the total production costs in bioethanol production. The most influential factors are: total investment costs, price of raw materials (price of biomass, ...
Thermal history and stress state of a fresh steam-pipeline influencing its remaining service life
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
The service life of thick-walled power plant components exposed to creep, as is the case with pipelines of fresh- and reheated steam, depend on the exhaustion rate of the material. Plant operation at elevated temperatures ...
