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 ...
A Heat Conduction and Convection Analytical Benchmark for Adjoint Solution Verification of Computational Fluid Dynamics Codes Used in Reactor Design
(Amer Nuclear Soc, La Grange Pk, 2016)
This work presents a heat transport benchmark problem when modeling the steady-state radial conduction in a fuel rod coupled to the axial heat convection in a coolant surrounding the rod and flowing along it. This benchmark ...
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 ...
The renewed TC12/ESIS technical committee - Risk analysis and safety of large structures and components
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
The ESIS Executive Committee decided to nominate a new team for the leadership and management of the TC12/ESIS technical committee (TC), as well as update the TC name as "Risk Analysis and Safety of Large Structures and ...
Hydrogen Embrittlement of Industrial Components: Prediction, Prevention, and Models
(Natl Assoc Corrosion Eng, Houston, 2016)
Hydrogen embrittlement is a common, dangerous, and poorly understood cause of failure in many metal alloys. In practice, it is observed that different types of damage to industrial components have been tied to the presence ...
Nanomaterials for skin care
(Springer International Publishing, 2017)
There are a lot of cosmetic products on the market based on nanotechnology. Those products contain nanomaterials since they have many advantages such as improved delivery of active ingredients, stability and photostability ...
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 ...
Effect of baffle cut and baffle spacing on pressure drop in shell and tube heat exchanger with U tubes
(Technium: Romanian Journal of Applied Sciences and Technology, 2020)
A general procedure for heat exchanger design has been presented in the Heat Exchanger Design Handbook (HEDH) [1], but no precise criterion for determining baffle cut nor baffle spacing has been offered, and the emphasis ...
Numeričko istraživanje bazenskog ključanja i mehanizama razmene toplote na zagrejačkom zidu
(Beograd : Savez mašinskih i elektrotehničkih inženjera Srbije (SMEITS), 2019)
Ključanje je fenomen koji se odvija u procesnim, termoenergetskim i hemijskim postrojenjima i
opremi. Precizno predviđanje koeficijenta prelaza toplote pri projektovanju i dimenzionisanju
opreme u kojoj se odvija ...
