Virtual consultant in welding - Creation of the content server
(Welding in the World, 2007)
In situations where the end users have no domain experts, a virtual consultant in a form of a software surrounding based on updated internet technologies may often show to them the procedure to follow in a given situation ...
Thermal-hydraulic analysis of a steam boiler with rifled evaporating tubes
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Rifled evaporating tubes are applied in the steam boilers with the aim to increase the steam-water mixture turbulization and to prevent the burnout of tubes walls. The rifled evaporating tubes and the working fluid forced ...
Study of the simulated heat affected zone of creep resistant 9-12% advanced chromium steel
(Taylor & Francis Inc, Philadelphia, 2008)
Global warming leads to research-development attempts worldwide with a view to reduce CO2 emission. Therefore, in the energy supply sector, a special focus has been directed to further development of steels that can endure ...
Variable Coefficients Model for Drying Processes with Conductive Heat Supply
(Taylor & Francis Inc, Philadelphia, 2009)
The proposed model is for heat and mass transfer inside a layer of moist material placed on hot isothermal surface. The relevant thermophysical properties of the material are considered as fully dependent on local temperature ...
Micromechanical estimates of the critical values of j-integral for the steel of steam pipelines
(Springer, New York, 2009)
We analyze the level of damage to 14MoV63 steel for steam pipelines under the conditions of crack-growth initiation according to the mechanism of ductile fracture. The state of the material after service for about 100,000 ...
Transition temperature and fracture mode of as-castand austempered ductile iron
(Wiley, Hoboken, 2008)
The ductile to brittle transition temperature is a very important criterion that is used for selection of materials in some applications, especially in low-temperature conditions. For that reason, in this paper transition ...
The effect of annealing temperatures and cooling rates on microstructure and mechanical properties of investment cast Ti-6Al-4V alloy
(Elsevier Sci Ltd, Oxford, 2006)
Production of investment castings of titanium alloys was considerably increased during last years due to the significant cost savings compared to complicated machined parts. However, the disadvantage of as-cast titanium ...
Modelling of ductile fracture initiation in strength mismatched welded joint
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
In this paper, the effect of strength mismatch and width of the welded joints oil the stress-strain distribution in the crack tip region has been discussed. The single-edge notched bend (SENB) specimens (precrack length ...
Analysis of fouling factor in district heating heat exchangers with parallel helical tube coils
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
This paper presents the results of measurements of thermal performance of 8 heat exchangers with parallel helical coils. Measurements were conducted in substations in 2 district heating systems in Serbia: Belgrade and ...
Simultaneous consideration of contingency factors and quality management: An empirical study of Serbian companies
(Academic Journals, Victoria Island, 2011)
The aim of the present paper is to answer whether the QM concept is universal or context-dependent, organic or mechanistic, and theoretical or practical in its essence. The study examines the impact of contingency factors ...
