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 ...
Stress Analysis of a Pipeline as a Hydropower Plant Structural Element
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2020)
This paper describes pipeline stress analysis, primarilybranch junctions, as a structural element in hydro-power plants. Pipelines are exposed to internal pressure,which is present under working conditions. Analysis of ...
Design of optimal flow concentrator for vertical-axis wind turbines using computational fluid dynamics, artificial neural networks and genetic algorithm
(Sage Publications Ltd, London, 2021)
Wind energy extraction is one of the fastest developing engineering branches today. Number of installed wind turbines is constantly increasing. Appropriate solutions for urban environments are quiet, structurally simple ...
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.). ...
The influence of incrustation and chute blockage on the dynamic behaviour of a bucket wheel excavator slewing superstructure
(Polish Soc Theoretical & Applied Mechanics, Warszawa, 2020)
Exploitation of bucket wheel excavators (BWEs) is accompanied by an increase of mass due to transport and adherence of a large amount of the material. Technical regulations do not account for the dynamic behaviour of BWEs. ...
Uticaj četvrte industrijske revolucije na stomatologiju / The fourth industrial revolution's impact on dentistry
(Srpsko lekarsko društvo, Beograd, 2021)
Uvod I najveći vizionari nisu mogli da pretpostave kojom brzinom će stomatološka struka i nauka prihvatiti koncept četvrte industrijske revolucije. Po obimu i složenosti ova transformacija je veća od svih do sada poznatih ...
Shortcut Method for Pipe Expansion Loop Sizing
(ASME, New York, 2020)
In the engineering practice, it is often necessary to define supporting scheme and expansion loop requirements for piping distribution systems in very early phases of a project. While placing pipe supports is a relatively ...
Inorganic fullerene-like nanoparticles and nanotubes of tungsten disulfide as reinforcement of carbon-epoxy composites
(Taylor & Francis Inc, Philadelphia, 2021)
A possibility was examined to enhance carbon-epoxy laminated composite mechanical properties by introducing a small concentration of reinforcing nanostructures - multi-wall onion-shaped fullerene-like nanoparticles of ...
Heat Dissipation from Stationary Passenger Car Brake Disc
(Assoc Mechanical Engineers Technicians Slovenia, Ljubljana, 2020)
This paper presents an experimental investigation of the heat dissipation from stationary brake discs concentrated on four disc designs: a ventilated disc with radial vanes, two types of ventilated discs with curved vanes ...
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, ...
