Experimental studies of wood chips charactristics influence on boiler performance and pollutant emissions
(Thermal Science, 2023)
Wood chips are often used as solid fuel in modern biomass boilers. Experiments were conducted on 22 boilers located in Serbia burning wood chips as fuel. The influence of wood chips characteristics is analyzed in relation ...
Hybrid artificial intelligence model for prediction of heating energy use
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
Currently, in the building sector there is an increase in energy use due to the increased demand for indoor thermal comfort. Proper energy planning based on a real measurement data is a necessity. In this study we developed ...
Experimental and numerical stress and strain analysis of the boiler reversing chamber tube plate
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
Boilers are one of the most used units for both heat generation plants and industry systems. Their operation is subjected to different working loads and maintenance requirements. Exploitation experience points out critical ...
Thermo-mechanical analysis of linear welding stage in friction stir welding influence of welding parameters
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
The influence of friction stir welding parameters on thermo-mechanical behav-ior of the material during welding is analyzed. An aluminum alloy is considered (Al 2024 T351), and different rotating and welding speeds are ...
Two-component propellant grain for rocket motor combustion analysis and geometric optimization
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
The paper considers utilization of rocket motor propellant grains that consist of two propellants. The idea is to achieve approximately neutral burning using an outer surface inhibited cylindrical shape and complex contact ...
Assessment of synergistic effect on performing the co-pyrolysis process of coal and waste blends based on thermal analysis
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
The preliminary thermogravimetric studies of co-pyrolyzed low rank coals (lignites Kostolac and Kolubara) with waste materials (spent coffee ground and waste rubber granulate) in a form of blends have been performed. Thermal ...
Initial development of the hybrid semielliptical-dolphin airfoil
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
Iosif Taposu has formulated a mathematical model and generated a family of air-foils whose geometry resembles the dolphin shape. These airfoils are characterized by a sharp leading edge and experiments have proven that ...
Thermal parameters defined with graph theory approach in synthetized diamonds
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
The Nanocrystaline diamonds are very important biomedical material with variety of applications. The experimental procedures and results have been done in the Institute of Functional Nanosystems at the University Ulm, ...
Identification and control of a heat flow system based on the Takagi-Sugeno fuzzy model using the grey wolf optimizer
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
Even though, it is mostly used by process control engineers, the temperature control remains an important task for researchers. This paper addressed two separate issues concerning model optimization and control. Firstly, ...
Optimal airfoil design and wing analysis for solar-powered high altitude platform station
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
The ability of flying continuously over prolonged periods of time has become target of numerous research studies performed in recent years in both the fields of civil aviation and unmanned drones. High altitude platform ...
