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 ...
The new experimental testing methodology for conveyor idler's fits control
(International Conference on Fracture, 2017)
The most common way to transfer tangential and axial loads in different types of assemblies is by interference fits. It is essential to determine interference fit parameters of pressed joints, which provides a proper ...
Fatigue crack growth in aluminum alloyt welded joint
(International Conference on Fracture, 2017)
The aim of the present investigation is to study the fatigue crack growth of welded T joints made of AA2024-T351 aluminum alloy. Three dimensional finite element models, with cracks as initial defects, will be constructed ...
Fracture mechanics in Serbia - 49 years of development
(International Conference on Fracture, 2017)
Development of fracture mechanics in Serbia has been presented. To start with, it was the Magister thesis of Prof. Stojan Sedmak, 49 years ago (1968), as the first milestone. The stress concentration problems have been ...
Temperature and time effects on fatigue strength of weldments
(International Conference on Fracture, 2017)
Temperature and service time effects on A-387 Gr. B Cr-Mo steel weldment fatigue strength have been evaluated. To assess service time effect on fatigue strength, samples are take from 40 years “old” material, whereas ...
Primarna i sekundarna regulacija snage na blokovima TENT B1 i B2 promenom protoka napojne vode kroz dodatni ekonomajzer
(Društvo termičara Srbije, 2016)
Ovaj rad se bavi numeričkim modeliranjem promene snage parnih blokova B1 i B2 u Termoelektrani „Nikola Tesla B“ koje su ostvarene promenom protoka napojne vode kroz dodatni ekonomajzer. Modelirano je zagrevanje napojne ...
Material characterization of the main steam pipeline made of 12%Cr tempered martensite ferritic steel after prolonged service
(International Conference on Fracture, 2017)
In the past decades, tempered martensitic ferritic steels with 9-12% chromium and containing carbide stabilizing elements have been widely used for components which operate within the creep range in power and industrial ...
Calculation of maximum tensile and shear forces in restorative materials using finite element method
(Trans Tech Publications Ltd, Durnten-Zurich, 2014)
The purpose of this paper was to determine tensile loading that leads to dental restoration failure, i.e. the critical values of stress. In order to analyze stress distribution within the restoration and tooth, mechanical ...
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 ...
Thermalhydraulics of once-through steam boiler tubes revisited
(Department of Thermal Technology, Gliwice, Poland, Silesian University of Technology 2020, 2020)
The analysis of pressure changes in water and steam flow along the entire once-through steam boiler
tube system was carried out. An efficient advanced method is developed and presented for the
prediction of once-through ...
