LES of flow around NACA 4412 airfoil at high angle-of-attack
(University of Belgrade, Faculty of Mechanical Engineering, 2022)
The flow field around a NACA 4412 airfoil is numerically investigated by means of large
eddy simulation (LES), an advanced mathematical model for turbulent flows which solves for
the low-pass filtered numerical solution. ...
Optimization of tribological behaviour of hybrid composites based on A356 and ZA-27 alloys
(Proceedings of the 10th International Conference on Tribology – BALKANTRIB '20, Belgrade, Serbia, 20 – 22 May 2021, 2021)
Optimization of tribological behaviour of hybrid composites based on A356 and ZA27 alloys reinforced with 10 wt. % SiC and 0, 1 and 3 wt. % Gr is presented in this paper. Optimization was performed using the Taguchi method ...
Structural analysis of small-scale composite propeller blade
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2021)
Contemporary, light-weight, unmanned air vehicles almost exclusively imply propeller rotors that enable them to hover, as well as to move vertically and horizontally at acceptable amount of required power (that is usually ...
Scanning of the characteristic dimensions of the control pattern for checking the railway wheel tread profile using a 3D scanner Atos core 200
(Belgrade : Innovation Center of Faculty of Mechanical Engineering, 2022)
Wheels for rail vehicles are made according to precisely defined geometry and dimensions. The wear of the
wheel profile in operation is not uniform, so the initial profile changes. It is a consequence of the inevitable ...
