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 ...
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. ...
Failure analysis of hydraulic turbine shaft
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
This paper describes the analysis of major failure of 28 MW horizontal hydro turbine shaft. The analysis of load carrying capacity of critical radius and fractography analysis are presented. Special emphasize is on ...
Experimental and numerical investigations of heat transfer in the first wall of Helium-Cooled-Pebble-Bed Test Blanket Module - Part 1: Presentation of test section and 3D CFD model
(Elsevier Science Sa, Lausanne, 2015)
This paper deals with cooling of the first wall of Helium-Cooled-Pebble-Bed Test Blanket Module (HCPB TBM) for ITER. The first wall cooling is an important investigation issue due to an extreme asymmetry of heat loads: ...
Experimental and numerical investigations of heat transfer in the first wall of Helium-Cooled-Pebble-Bed Test Blanket Module Part 2: Presentation of results
(Elsevier Science Sa, Lausanne, 2015)
This paper is the continuation of the first report on investigations of heat transfer in the first wall of Helium-Cooled-Pebble-Bed Test Blanket Module for ITER submitted to this Journal (see Ilic et al. [ID. The investigations ...
Set-up of a pre-test mock-up experiment in preparation for the HCPB Breeder Unit mock-up experimental campaign
(Elsevier Science Sa, Lausanne, 2013)
The complexity of the experimental set-up for testing a full-scaled Breeder Unit (BU) mock-up for the European Helium Cooled Pebble Bed Test Blanket Module (HCPB-TBM) has motivated to build a pre-test mock-up experiment ...
Experimental investigations of flow distribution in coolant system of Helium-Cooled-Pebble-Bed Test Blanket Module
(Elsevier Science Sa, Lausanne, 2016)
This paper deals with investigations of flow distribution in the coolant system of the Helium-Cooled Pebble -Bed Test Blanket Module (HCPB TBM) for ITER. The investigations have been performed by manufacturing and testing ...
Thermal-hydraulics of helium cooled First Wall channels and scoping investigations on performance improvement by application of ribs and mixing devices
(Elsevier Science Sa, Lausanne, 2016)
The first wall (FW) of DEMO is a component with high thermal loads. The cooling of the FW has to comply with the material's upper and lower temperature limits and requirements from stress assessment, like low temperature ...
Tie-rods of the bucket wheel excavator slewing superstructure: A study of the eye plate stress state
(Elsevier Sci Ltd, Oxford, 2020)
Tie-rods of the bucket wheel and counterweight booms are vital parts of the bucket wheel excavator slewing superstructure. This paper is dedicated to the problem of identifying the stress state of the critical cross-section ...
