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 ...
Creep crack growth behavior of p91 steel weldments
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
The steels operating at elevated temperatures are well known to be exposed to premature failure due to cracking caused by constant thermal stress, i. e. secondary creep process. Therefore, creep crack growth tests were ...
Experimental and numerical analysis of thermo-chemical erosion in gun steel
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
Various factors of thermo-chemical erosion process in gun steel were analysed. The factors are mainly related to the thermal load of gun barrel inside surface, characteristics of barrel surface and chemical interactions ...
Temperature fields in linear stage of friction stir welding effect of different material properties
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
Friction stir welding is one of the procedures for joining the parts in solid state. Thermo-mechanical simulation of the friction stir welding of high-strength aluminium alloys 2024 T3 and 2024 T351 is considered in this ...
Air staging application effects on overall steam boiler operation
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2019)
This paper presents the results of calculation system of main processes in power steam boiler, before and after application of air staging. Modified air injection scheme was implemented during 2015 on the power steam boiler ...
Importance of on-time decision making in energy sector based on perspectives case study new stavalj project
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
Expression "Development conditions and perspectives" became important for numerous analyses in various industrial and social areas. Several strategic documents and studies in last two decades analysed projects with topics ...
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 ...
