determining the reliability function of the thermal power system in power plant "nikola tesla, block b1"
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2015)
Representation of probabilistic technique for evaluation of thermal power system reliability is the main subject of this paper. The system of thermal power plant under study consists of three subsystems and the reliability ...
Influence of application of Hottel's zonal model and six-flux model of thermal radiation on numerical simulations results of pulverized coal fired furnace
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2012)
Difference of results of numerical simulation of pulverized coal fired furnace when mathematical models contain various radiation models has been described in the paper. Two sets of numerical simulations of pulverized coal ...
Application and design of an economizer for waste heat recoveryin a co-generation plant
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
Energy increase cost has required its more effective use. However, many industrial heating processes generate waste energy. Use of waste-heat recovery systems decreases energy consumption. This paper presents case study ...

Temperature and heat effects on polyethylene behaviour in the presence of imperfections
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
This paper highlights the changes of polyethylene behaviour during various loading rates as well as the influence of test temperature on the material characteristics. Passive infrared thermography method and a high speed ...
Influence of material velocity on heat generation during linear welding stage of friction stir welding
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2016)
The heat generated during friction stir welding process depends on plastic deformation of the material and friction between the tool and the material. In this work, heat generation is analysed with respect to the material ...
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 ...
