Experimental and numerical analysis of flow field and ventilation performance in a traffic tunnel ventilated by axial fans
(Srpsko društvo za mehaniku, Beograd, 2018)
To investigate air flow in longitudinally ventilated traffic tunnels, a scaled model of a typical road-traffic tunnel with an appropriate ventilation system based on axial ducted fans, is designed and built in the Lab. The ...
On the influence of turbulent kinetic energy level on accuracy of k - epsilon and lrr turbulence models
(Srpsko društvo za mehaniku, Beograd, 2018)
This paper presents research regarding the influence of turbulent kinetic energy (TKE) level on accuracy of Reynolds averaged Navier-Stokes (RANS) based turbulence models. A theoretical analysis of influence TKE level on ...
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 ...
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 ...
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 ...
Numerical study on aerodynamic drag reduction of a tractor-trailer model
(7th International Congress of Serbian Society of Mechanics, 2019)
Numerical investigation of the flow structure and computations of drag force around Generic
Conventional Model (GCM) of tractor-trailer is analyzed in this paper. Starting from original GCM,
three additional changes on ...
CONTROL VALVES TRIM DESIGN, RETROFITTING AND TESTING
(Full Papers Proceedings of International Conference "IEEP 2022", November 08-09, 2022, Faculty of Mechanical Engineering of the University of Belgrade, Belgrade, Serbia, 2022)
Control valves have numerous applications like in natural gas control and transport (as anti surge and recycle valves, hot/cold bypass valves, throttling valves, degasser flow/level control valves), natural gas treatment ...
The Influence of Roughness Change on Ship Resistance in CFD Simulations
(Inno GatinMilovan Perić, 2022)
The biofouling of ship hulls has a significant impact on both the environment and the ship. A negative effect on the environment is manifested by an increase in pollution with greenhouse gasses and disrupting the ecosystem ...
Energy Saving Devices Performance Assessment Using CFD
(Volker Bertram, 2022)
In the wake of the new EEXI regulations, a lot of attention has been given to quantifying power savings (or losses) generated by various Energy Saving Devices available on the market. These come in many different variations, ...
