Possibilities to increase power and efficiency of hydro generating unit
(42nd International Conference on Large High Voltage Electric Systems 2008, CIGRE 2008, 2008)
Within the scope of preparation and planning the revitalization, efforts are made in order to increase the output power and efficiency of generator and turbine. Thereby, it is necessary to carry on analysis of possible ...
The heat and mass transfer in a large lignite coal particle devolatilizing in FB
(TuTech Innovation GmbH, 2008)
A theoretical study has been performed in order to investigate heat and mass transfer processes in a lignite particle during the devolatilization. A mathematical model, describing the devolatilization process, has included ...
The impact of worn out tool on the character and type of chip formation
(Institute of Mechanical Engineering, 2009)
Security of gas pipelines
(Springer, Dordrecht, 2009)
Security of the natural gas supply strongly depends on the integrity of the transportation pipelines. The statistical evidence shows that the most probable cause of the break occurrence at natural gas pipeline is the ...
Numerička analiza loma zatezne epruvete sa prslinom u ZUT / Numerical analysis of tensile specimen fracture with crack in HAZ
(Kluwer Academic Publishers, 2006)
Numeričkim rešenjima se omogućava istraživanje složenijih problema, uključujući analizu pojedinačnih uticaja, posebno u slučajevima kada izostaju odgovarajući eksperimenti i matematička rešenja usled visoke cene, složenosti ...
Experimental determination of J-integral at elevated temperatures
(17th European Conference on Fracture 2008: Multilevel Approach to Fracture of Materials, Components, 2008)
In past two decades, the development of 9-12% Cr creep-resistant steel for critical components in coal-fired power stations that can withstand higher temperatures and pressures has been intensified in order to increase ...
Structural integrity assessment by local approach to fracture

Evaluation of damage of steam pipeline steel using local approach to fracture
(American Society of Mechanical Engineers, Pressure Vessels and Piping Division (Publication) PVP, 2008)
In the paper, the level of damage of steam pipeline steel after about 100,000 hours at 540°C (1004 °F) under pressure of 42 bars (609 PSI) is analyzed. Material degradation is estimated using a combined experimental and ...
Visualization of submerged cavitating jet: Part one -the phenomenon, time-synchronization, photo objectives and sono-luminescence
(Proceedings of the 16th Australasian Fluid Mechanics Conference, 16AFMC, 2007)
In order to study the jet structure and the behavior of cloud cavitation within time and space, visualization of highly submerged cavitating water jet has been done using 4-Quik-05 camera. This included obligatory ...
