Model analysis of complex structures - advantages of physical sub-scaled model testing and shortcomings in physical model production
(Elsevier Science Bv, Amsterdam, 2018)
The possibilities of testing real constructions strength are often limited, especially in case of large constructions. Testing on the model, instead of the actual construction, results in a great saving of money and time. ...
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 ...
Oxidation behavior during prolonged service of boiler tubes made of 2.25Cr1Mo and 12Cr1Mo0.3V heat resistance steels
(Elsevier Science Bv, Amsterdam, 2016)
During service of thermal power plant (TPP) units, different components are exposed to high temperature due to technological cycle of TPP unit. Service lifetimes of these components, especially boiler heating surfaces, may ...
Towards a unified and practical industrial model for prediction of hydrogen embrittlement and damage in steels
(Elsevier Science Bv, Amsterdam, 2016)
Bearing in mind the multiple effects of hydrogen in steels, the specific mechanism of hydrogen embrittlement (HE) is active, depending on the experimental conditions and numerous factors which can be grouped as environmental, ...
Heat transfer and lubrication of turboshaft motor-reducer

This paper presents the results and methods used for determining of fracture toughness of reactor steel, denoted as 20MnMoNi55, typically used for structures working at low temperatures, in transition temperature area. In ...
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 ...
The influence of illumination parameters on the performances of color sorting machines
(Scientific Proceedings XII International Congress "Machines, Technologies, Materials" 2015, 2015)
The color recorded in the image is not an inherent value of observed object, because it is also influenced by the illumination properties, as well as geometry and surfaces of neighboring objects. Numerous studies have ...
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 ...
