Mobility of positive ions in CF4
(IOP Publishing Ltd, Bristol, 2014)
Cross-section sets for transport of positive ions in CF4 that fit the available experimental data for mobility are assessed by normalizing the available experimental and theoretical cross-sections within the framework of ...
Experimental determining of fracture behaviour of P460NL1 steel welded joint specimens
(Elsevier Science Bv, Amsterdam, 2019)
This paper is focused on the experimental measuring of impact energy as a part of the doctoral dissertation involving the fatigue behaviour of welded joints, made of fine grain normalised micro-alloyed low carbon high ...
Conceptual design of solar-powered high-altitude long endurance aircraft
(University of Belgrade, Faculty of Mechanical Engineering, 2022)
The design of high-altitude unmanned aerial vehicles is one of the most current research
topics today in the field of aviation. The possible purposes of such flying platforms are
numerous, from communication hubs, terrain ...
Analysis of Crossing and Veering Phenomena in Planar Frame Structures
(Univerzitet u Beogradu, Mašinski fakultet, 2022)
In this paper, crossing and veering phenomena are discussed for a two-element frame consisted of beams of constant circular cross-sectional area, mass density and modulus elasticity, see Fig. 1. Depending on the mechanical ...
Simulating flow in silicon Y-bifurcated microchannels
(University of Belgrade, Faculty of Mechanical Engineering, 2022)
Microfluidic devices are excessively used for various biomedical, chemical, and engineering
applications. The most common microfluidic platforms are obtained from
polydimethylsiloxane (PDMS). Platforms based on etched ...
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. ...
Parametric frequency analysis of oscillatory behavior of mouse Zona Pellucida spherical net model: cases of successful and of unsuccessful fertilization
(Wiley Online Library, 2013)
The current paper proposes a model for describing mechanical phenomena that occur during the process of mammal fertilization when spermatozoa impact the surface of Zona Pellucida. Zona pellucida (ZP) is a dynamical 3D ...
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 ...
Influence of the amount of metal-containing additive on performance characteristics of lubricant based on rapeseed oil
(Proceedings of the 10th International Conference on Tribology – BALKANTRIB '20, Belgrade, Serbia, 20 – 22 May 2021, 2021)
The paper exposes experimental results of the performance characteristics (coefficient of friction, contact temperature and wear) of the biolubricant based on rapeseed oil. The amount of commercial metal-containing additive ...
