Numerical simulation of non-conventional liquid fuels feeding in a bubbling fluidized bed combustor
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2013)
The paper deals with the development of mathematical models for detailed simulation of lateral jet penetration into the fluidized bed, primarily from the aspect of feeding of gaseous and liquid fuels into fluidized bed ...
On the extension of the erdos-mordell type inequalities
(Element, Zagreb, 2014)
We discuss the extension of inequality R-A >= c/a r(b) + b/a r(c) to the plane of triangle Delta ABC. Based on the obtained extension, in regard to all three vertices of the triangle, we get the extension of Erdos-Mordell ...

TRIZ methodology provides an opportunity for improving the classical engineering approach based on personal knowledge and experience. This paper presents the application of TRIZ methods for improving vehicle maintenance ...
Research of combustion in older generation spark-ignition engines in the condition of use leaded and unleaded petrol
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
This paper analyzes the potential problems in the exploitation of the older generation of spark-ignition engines with higher octane number of petrol (unleaded petrol BMB 95) than required (leaded petrol MB 86). Within the ...
A neuro-fuzzy based combustion sensor for the control of optimal engine combustion efficiency
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2013)
Modern and advanced control systems for internal combustion engines require accurate feedback information from the combustion chamber. Whereas the in-cylinder pressure sensor provides this information through its close ...
Fracture mechanics analysis of damaged turbine rotor discs using finite element method
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
This paper presents evaluation fracture mechanics parameters in low pressure turbine components. Critical locations such as keyway and dovetail area are experiencing stress concentration leading to crack initiation. Stress ...
Design of coupled slider crank mechanism for orbiting motion
(Daaam International Vienna, Vienna, 2015)
The paper describes development of a novel orbiting mechanism. Target design is a shaking mechanism with a planar figure eight closed loop. Shaking dynamics depends on a cycling frequency as well on a reciprocating ...
