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 ...
XRF and LIBS measuring on metal and ceramic laser-cleaned surfaces
(IMEKO-International Measurement Federation Secretariat, 2016)
The use of lasers in the conservation of artefacts plays an important role since its posibilities of safe, efficient and efective cleaning on complex surfaces and wide range of materials. This paper presents the results ...
Creep crack growth - Comparison of two steel P91 and P22
(International Conference on Fracture, 2017)
The deformation and crack growth behaviour of P22 and P91 steel weldments tested at 550 °C and 600 °C, respectively,compact C(T) type specimens with sharp EDM starter notches in the base metal (BM) and heat affected zone ...
Numerical analysis of fracture of non-standard ring specimen for examination of axially flawed cylindrical structures
(International Conference on Fracture, 2017)
Integrity of cylindrical structures, such as pipes and small-scale pressure vessels, is typically assessed by testing fracture mechanics specimens, like compact tensile CT or single-edge notched bending, SENB. However, ...
Temperature and time effects on fracture toughness values in welded joint
(International Conference on Fracture, 2017)
Temperature and time effects on fracture toughness have been investigated for characteristic regions in a welded joint made of Cr-Mo steel A-387 Gr. B. Comparative analysis of fracture toughness values for characteristic ...
Numerical simulation of fatigue crack growth in welded pipes
(International Conference on Fracture, 2017)
Numerical simulation of fatigue crack growth has been performed by using the extended finite element method (xFEM) for modeling fatigue crack growth in a pipe made of API j55 steel by high-frequency welding. The obtained ...
Measuring of Strain and Displacements in Welded Joints Subjected to Tensile Load Using Stereometric Methods
(Springer-Verlag Berlin, Berlin, 2017)
During the experimental testing of a welded joint, made of steel P460NL1, complete strain and displacement fields, which provide full insight into the behaviour of a welded joint under tensile load, were obtained using an ...
Increased hydraulic resistance in tubes of once-through boiler due to fouling: a case study of 650 MWe ligite fired unit
(Beograd : Savez mašinskih i elektrotehničkih inženjera i tehničara Srbije (SMEITS), 2022)
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 ...
Povećanje energetske efikasnosti parnog bloka iskorišćenjem otpadne toplote dimnog gasa
(Beograd : Savez mašinskih i elektrotehničkih inženjera Srbije (SMEITS), 2021)
U termoelektranama sa starijim projektnim rešenjima postoji značajan potencijal za iskorišćenje otpadne toplote
dimnih gasova. Otpadna toplota dimnog gasa se može iskoristiti primenom zagrejača vode visokog pritiska ...
