Techno-economic analysis of gas turbine-based chp plant operation under a feed-in tariff system
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
This paper deals with the techno-economic analysis of gas turbine-based combined heat and power production, within a current local legislation frame for the promotion of such production of energy in the Republic of Serbia. ...
Kinetic parameters identification of conductive enhanced hot air drying process of food waste
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2021)
The efficient utilization of waste from food industry is possible after thermal treatment of the material. This treatment should be economically feasible and compromise the energy efficient drying process. The main goal ...
Numerical evaluation of thermal stresses generated in laminated composite structure exposed to low temperatures
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2021)
This paper presents numerical calculation of thermal stresses generated in a carbon fiber-epoxy laminated composite structure which is operating at low temperatures. The thermal stress evaluation is based on the finite ...
Study of vacuum and freeze drying of bee honey
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
The aim of this research is to study the drying kinetics of vacuum-dried and freeze-dried bee honey produced from two different varieties: Sunflower honey (Helianthus Annuus L.) and Acacia honey (Robinia pseudo acacia L.). ...
Fluid dynamic forces in the main steam pipeline of thermal power plant upon stop valves closure
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
A steam turbine trip is followed by a prompt closure of stop valves in front of the turbine and consequently to a pressure rise in the main steam pipeline. This steam hammer transient leads to the generation of intensive ...
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 ...
Study and analysis of the cavitating and non-cavitating jets part one parameters controlling force, power, and the jet behavior
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
This paper presents the dependency of the jet power and the cavitation intensity on the working conditions of the cavitating and non-cavitating jet flow. This dependency is indicated by the cavitation erosion process and ...
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, ...
Numerical analyses of a hydraulic hybrid powertrain system for a transit bus
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2020)
A dynamic programming optimization algorithm has been applied on a transit bus model in MATLAB in order to assess the fuel economy improvement potential by implementing a hydraulic hybrid powertrain system. The numerical ...
Butler-volmer current equation and fractal nature correction in electrochemical energy
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2021)
The Global Energy Crisis necessitated improving research into new, renewable and alternative energy sources. Due to that, our focus is on the area of some phenomena and applications where different synthetic methods and ...
