Explosive boiling of water films based on molecular dynamics simulations: Effects of film thickness and substrate temperature
(Elsevier, 2023)
This paper deals with investigations of mechanisms governing explosive boiling of water films on hot copper substrate with plain surface. The investigations are based on results of molecular dynamics (MD) simulations in ...
Erosion Wear Behavior of High Chromium Cast Irons
(Springer, 2023)
In this study, two high chromium cast irons
(HCCI) with different chromium content (15%Cr and
25%Cr), in as-cast and annealed conditions (heat-treated,
HT), were tested to determine the erosion wear behavior of
these ...
Increased hydraulic resistance in tubes of once-through boiler due to fouling: A case study of 650 MWe ligite fired unit
(Elsevier, 2023)
The analysis of pressure changes in water and steam flow along the entire once-through steam boiler tube system at the 650 MWe lignite fired Unit was carried out after the long operational period of almost 30 years without ...
Effect of building direction and heat treatment on mechanical properties of Inconel 939 prepared by additive manufacturing
(Springer Nature, 2023)
This study investigated the effect of building direction (BD) and three-step heat treatment on the microstructure and mechanical properties of a nickel-based superalloy Inconel 939 produced by additive manufacturing (AM), ...
Damage Analysis on Tooth Gear Ring of a Bucket-Wheel Excavator
(Trans Tech Publications Ltd, Switzerland, 2023)
This paper deals with damage analysis of gear ring after manufacturing process, just before in-service period. Tooth gear ring segments were made of 40MnCrSi3V low-alloyed cast steel, which chemical composition and mechanical ...
Energy efficiency in electric vehicles
(SMEITS, 2023)
This paper deals with research and analysis of energy efficiency in electric vehicles. In the
context of the increasing popularity of electric vehicles as a viable alternative to traditional internal
combustion vehicles, ...
Influence of mechanical properties of welded joint regions on pipeline structural integrity
(The 27th International Conference on Fracture and Structural Integrity, 2023)
In this paper, a material characterization inverse methodology is used to obtain
structural parameters for all welded joint regions. Furthermore, such are applied for
the more realistic analysis of the pipeline numerical ...
Environmental status in correlation with water quality parameters of the South Morava river
(Akademija nauka i umjetnosti Republike Srpske, 2023)
The South Morava River is very important resource for the City of Vranje. Its water serves for irrigation of agricultural land and for drinking, so the water quality and its environmental status is of great importance. ...
Integrity of Welded Joints Made of Alloy NiCr21Mo
(Društvo za integritet i vek konstrukcija „Prof. dr Stojan Sedmak“, Institut za ispitivanje materijala (IMS), Beograd, 2023)
The research covers the investigation of mechanical properties of welded joint made on NiCr21Mo alloy (commercial trademark Incoloy 825), and joints of steels P355GH and X2CrNiMo17-12-2, as well as the influence of the ...
Environmental, social and other non-profit impacts Of mountain streams usage as Renewable energy resources
(Technical Institute of Bijeljina Republic of Srpska - Bosnia and Herzegovina, 2023)
The main subject of this manuscript is mountain streams used by construction of small hydro power plants. The motivation for this research stemmed from a number of conflicting opinions about the justification of the ...
