Environmental Impact Assessment of the Nuclear Reactor in Vinca, Based on the Data on Emission of Radioactivity from the Literature - a Modeling Approach
(Chemical Industry and Chemical Engineering Quarterly / CICEQ, 2015)
Research activities of Vinca Institite have been based on two heavy water research reactors: a 10 MW one, RA, and zero power, RB. Reactor RA was operational from 1962 to 1982. In 2010, spent fuel has been sent to the country ...
The Application of Experimental Design Methodology for the Investigation of Liquid Radioactive Waste Treatment
(Nuclear technology and radiation protection, 2017)
The sorption properties of waste facade, brick, and asphalt sample towards Sr(II), Co(II), and Ni(II) ions from single and multicomponent solutions were investigated. The highest sorption capacity was found for Ni(II) ions, ...
Mathematical Modeling of Environmental Impacts of a Reactor Through the Air
(Nuclear technology and radiation protection, 2014)
This paper presents an algorithm for the calculation of internal and external doses as an integral part of the mathematical model of atmospheric dispersion. The air pollution dispersion model is used on average annual ...
On the improved finite volume procedure for simulation of turbulent flows over real complex terrains
(Journal of Computational Physics, 2015)
This article presents a new and substantially improved finite volume procedure for simulation of incompressible flows on non-orthogonal grids. Cell-centered least-squares gradients are obtained in a robust and highly ...
Pahs Levels in Gas and Particle-Bound Phase in Schools At Different Locations in Serbia
(Chemical Industry and Chemical Engineering Quarterly / CICEQ, 2015)
This study investigated seasonal variation of PAHs and their partition between gas and particulate-bounded phases in indoor and outdoor air in 4 schools In Serbia located at different locations. The sampling campaigns were ...
Modeling air concentration of fly ash in Belgrade, emitted from thermal power plants TNTA and TNTB
(Process Safety and Environmental Protection, 2017)
The aim of the study was to estimate if dust/fly ash emitted into the atmosphere from chimneys and the ash disposal sites of the thermal power plants Nikola Tesla A and B in Obrenovac could increase the concentration of ...
New non-orthogonality treatment for atmospheric boundary layer flow simulation above highly non-uniform terrains
(Thermal Science, 2016)
In this paper we validate an improved finite volume approximation of Reynolds averaged Navier-Stokes equations for simulation of wind flows in body-fitted grids generated by algebraic extrusion from digital terrain elevation ...
On the use of small and cheaper sensors and devices for indicative citizen-based monitoring of respirable particulate matter
(Elsevier, 2015)
Respirable particulate matter present in outdoor and indoor environments is a health hazard. The particle concentrations can quickly change, with steep gradients on short temporal and spatial scales, and their chemical ...
Mechanism of Primary Fragmentation of Coal in Fluidized Bed
(Thermal Science, 2016)
In order to lay a foundation of a credible primacy fragmentation model, a theoretical analysis of the thermo-mechanical processes in a devolatilizing solid fuel particle was carried out. The devolatilization model comprises ...
Experimental and Numerical Investigation of the Primary Fragmentation of a Lignite during Fluidized-Bed (FB) Devolatilization
(Energy and Fuels, 2015)
The paper presents a comparison between experimental and model results of primary fragmentation of a lignite coal in a fluidized bed (FB). In the experiments, the char particle size distribution and the general indicators ...
