Balance of liquid-phase turbulence kinetic energy equation for bubble-train flow
(Atomic Energy Soc Japan, Tokyo, 2004)
In this paper the investigation of bubble-induced turbulence using direct numerical simulation (DNS) of bubbly two-phase flow is reported. DNS computations are performed for a bubble-driven liquid motion induced by a regular ...
New modular concept for the helium cooled pebble bed test blanket module for ITER
(Elsevier Science Sa, Lausanne, 2005)
Starting from the latest European design of the HCPB blanket for the DEMO a test blanket module for ITER has been deduced. The paper describes the new design and presents the rational of the design choices and the results ...
Failure investigation of the bucket wheel excavator crawler chain link
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The high mobility of open pit machines in heavy duty conditions provides fertile ground for the occurrence of various failures of the traveling mechanisms' vital parts such as chain links. The goal of the study presented ...
The fundamental role of fluid dynamic analyses in the design of the solid EU Test Blanket Module
(Elsevier Science Sa, Lausanne, 2012)
In the frame of the activities of the European Test Blanket Module Consortium of Associates, the Helium Cooled Pebble Bed Test Blanket Module (HCPB TBM), the so-called solid TBM, is developed in Karlsruhe Institute of ...
Effects of operation temperature on thermal expansion and main parameters of radial ball bearings
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2015)
The research of influence of operation temperature on the thermal expansion and main parameters of radial ball bearings is presented in this paper. The main bearing parameters are identified in accordance with the increasing ...
Study on impact properties of creep-resistant steel thermally simulated heat affected zone
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2012)
The steam pipe line and steam line material, along with its welded joints, subject to damage that accumulates during operation in coal power plants. As a result of thermal fatigue, dilatation of steam pipe line at an ...
Explicit parametric method for optimal spur gear tooth profile definition
(Trans Tech Publications Ltd, 2013)
The gear tooth profile has an immense effect on the main operating parameters of gear pairs (load capacity, working life, efficiency, vibrations, etc). In current engineering research and practice, there is a strong need ...
Failure analysis of the mobile elevating work platform
(Elsevier Ltd, 2015)
This paper presents an investigation of the accident which occurred during startup of the extending structure from the transport position. In order to clarify the causes of crack occurrence along almost the entire surface ...
Assessment of the effect of pitting corrosion on fatigue crack initiation in hydro turbine shaft
(Trans Tech Publications Ltd, 2013)
Energy efficiency is a key issue worldwide, and not confined solely to the realm of engineers. Past failures of mechanical power system components must be examined carefully in order to minimise future occurrences and ...
Second-Order Adjoint Sensitivity and Uncertainty Analysis of a Heat Transport Benchmark Problem-II: Computational Results Using G4M Reactor Thermal-Hydraulic Parameters
(Amer Nuclear Soc, La Grange Pk, 2016)
This work presents numerical results for the second-order sensitivities of the temperature distributions in a paradigm benchmark problem modeling heat transport in a reactor fuel rod and the surrounding coolant channel. ...
