Karakterizacija zavarenih spojeva cevi od čelika X20CrMoV121 dobijenih različitim tehnologijama zavarivanja
(International Conference "Power Plants 2016" 23rd – 26st November 2016 Zlatibor, Srbija, 2016)
Toplotno postojani martenzitni čelik X20CrMo12 1 je našao široku primenu na domaćim termoenergetskim (TE) postrojenjima za izradu izlaznih sekcija pregrejača cevnog sistema kotla, kao i debelozidih komponenti kao što su ...
Influence of Geometry on Pressure and Velocity Distribution in Packed-bed Methanol Steam Reforming Reactor
(Amer Inst Physics, Melville, 2017)
The main tasks of this research is to propose several changes in the packed bed micro methanol steam reformer geometry in order to ensure its performance. The reformer is an integral part of the existing indirect internal ...
Metalizacija velikim brzinama u struji produkata sagorevanja - HVOF
(Belgrade : Singidunum University, 2015)
Service life extension of machine parts and equipment are increasingly being based on protection of certain, particularly endangered areas, by applying the coating. In order to increase the resistance of mechanical parts, ...
A simple digital imaging method for the analysis of the color of food surfaces
(Faculty of Mechanical Engineering, University of Belgrade, 2015)
Compared to manual inspection, which is inconsistent and subjective, sorters are able to assure product quality and food safety by more effectively identifying and removing defects and foreign material, while at the same ...
COST ANALYSIS OF SHELL AND TUBE HEAT EXCHANGERS WITH CONCENTRIC HELICAL TUBE COILS
(Belgrade : Faculty of Mechanical Engineering, 2015)
The paper deals with the manufacturing costs of shell and tube heat exchangers with concentric helical tube coils. The most common correlations for calculating prices of shell and tube heat exchangers found in open literature ...
Microstructural characterization of WC and CrC based coatings applied by different processes
(Associations of Metallurgical Engineers of Serbia - AMES, 2015)
Numerous mechanical structures and assemblies have frequent outages
because of wear of machine parts due to the effects of abrasion and erosion.
There are several methods to protect parts from wear and one of them is ...
3D profiling of 12Cr heat resistante steel charpy V noch fracture surface obtained at different temperatures
(Faculty of Mechanical Engineering, University of Belgrade, 2015)
Characterization of metal degradation after prolonged
service is necessary for evaluating component
exhaustion and its remaining service capability.
Martensitic steel X20CrMoV 12.1 has
been extensively used as a material ...
Structural Integrity Assessment by Using Cross-Correlated Modal Identification
(Elsevier Science Bv, Amsterdam, 2018)
Early researches on steel structures integrity were mainly oriented on calculations and conventional experiments. Robust numerical methods of a high accuracy are usually less reliable in estimation of dynamic properties ...
Methodology optimization tests of composite rotor blades of helicopters in extreme conditions
(DANUBIA Adria Symposium on Advances in Experimental Mechanics, 2018)
Application of an economizer for waste heat recovery in a 1415 kwe cogeneration plant
(Sopot : Scientific association for development and affirmation of new technologies, 2015)
Increase of energy cost has required its more effective use. However, many industrial heating processes generate waste energy. Use of waste-heat recovery systems decreases energy consumption. This paper presents case study ...
