Wear resistance improvement of thermal plant fan mill impact plates based on numerical flow simulation
(Institut za ispitivanje materijala, Beograd, 2017)
Numerical simulation of 3D multiphase flow is performed to determine the velocity field in the fan mill. The mixture model of the Euler-Euler approach is used. Recirculating gas is a primary phase that carries granular ...
Prenos toplote i termomehaničko ponašanje atmosmosferskog gorionika kućne gasne grejalice / Heat transfer and thermo-mechanical behavior of the domestic heater atmospheric burner
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
Rad izlaže realizovanu 3D CFD simulaciju faze paljenja gasnog gorionika sa ciljem određivanja maksimalne temperaturske razlike koja u njemu izaziva maksimalne termičke napone. Proces je nestacionaran. Simulacije je realizovana ...
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 ...
Numerička simulacija strujanja unutar korenog dela industrijskog dimnjaka sa više dimovodnih kanala
(Savez energetičara, 2012)
Pregrade unutar korenog dela čeličnih industrijskih dimnjaka sprečavaju međusobni uticaj struja dimnih gasova iz naspramno postavljenih dimovodnih kanala. U slučaju nesimetričnosti masenih protoka i različitih temperatura ...
Numerical Study of the L/D Ratio and Turbulent Prandtl Number Effect on Energy Separation in a Counter-Flow Vortex Tube
(Isfahan Univ Technology, Isfahan, 2022)
Vortex tube is a device without moving parts with ability to separate pressurized gas into two streams: cold and hot. This is a consequence of the Eckert-Wiese effect, which is responsible for spontaneous redistribution ...
Numerical Investigation and Optimization of a Morphing Airfoil Designed for Lower Reynolds Number
(MDPI, 2024)
A novel concept of morphing airfoils, capable of changing camber and thickness, is proposed. A variable airfoil shape, defined by six input parameters, is achieved by allowing the three spinal points (at fixed axial ...
Experimental and numerical research of the flow inside the control valves trim
(VINČA Institute of Nuclear Sciences, 2024)
In this paper are presented desing, testing and numerical analysis for two manufactured control valve trims. Valve trim is consisted of cage or dick stack, plug, stem and seat. Size from app. 15.88 mm (0.625 in) up to 101.6 ...
Experimental and numerical investigation of thermal and flow conditions inside a large pharmaceutical storage after the ventilation system failure
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
Safe storage of pharmaceutical products is of great importance due to potential hazards for human health. The aim of this study was to assess the ability of phar-maceutical storage to recover design temperature during ...
DEM analiza protoka zrnastog materijala u statičkoj mešalici / DEM analysis of the granular flow in the static mixers
(Nacionalno društvo za procesnu tehniku i energetiku u poljoprivredi, Novi Sad, 2016)
Statičke mešalice se koriste za mešanje pre glavnog procesa mešanja, čime se značajno smanje vreme mešanja i potrošnja energije. U ovom radu, prikazana je upotreba metode diskretnih elemenata (engl. Discrete Element Method ...
