Thermohydraulic experimental design for the European Helium-Cooled-Pebble-Bed Test Blanket Module
(Elsevier Science Sa, Lausanne, 2008)
The peculiarities of the coolant flow in Helium-Cooled-Pebble-Bed Test Blanket Module (TBM) are (i) very intensive heating of the first wall from the plasma side and (ii) very complicated geometry of How domain consisting ...
Microstructural and tribological properties of A356 Al-Si alloy reinforced with Al2O3 particles
(Springer/Plenum Publishers, New York, 2008)
In the present study, the effect of the Al2O3 particles (average size of 12 mu m, 3 and 10 wt.%) reinforcement on the microstructure and tribological properties of Al-Si alloy (A356) was investigated. Composites were ...
Modeling, simulation, and control of an electromechanical aerofin control system with a PWM-controlled DC motor
(Automatic Control and Computer Sciences, 2008)
A nonlinear model of an electromechanical actuator (EMA) system for aerofin control is presented. The EMA is realized with a permanent magnet brush DC motor controlled by a constant current driver. In this paper we introduced ...
Predictions of heat transfer from a flat plate to impinging jet by numerical simulations
(Silesian University of Technology, 2008)
A numerical investigation is carried out to predict heat transfer and turbulent fluid flow in an axisymmetric turbulent impinging jet. Four common near-wall two-equation-and three Reynolds stress models were considered in ...
Context sensitive recognition of abrupt changes in cutting process
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
This paper presents a new generic approach to real-time monitoring of abrupt changes in cutting process. Proposed method is based on hierarchical fuzzy clustering of patterns obtained from discrete wavelet transform (DWT) ...
Development and application of crack parameters
(Springer, Dordrecht, 2009)
The development, definition and implementation of crack parameters (stress intensity factor, crack tip open displacement, J integral, filial stretch zone) are presented. They are now used for structural integrity and ...
Dynamics of steam accumulation
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Steam accumulators are applied as buffers between steam generators and consumers in cases of different steam production and consumption rates. The steam accumulator is filled with water and steam and it operates with a ...
Analysis and optimization of dynamically loaded porous metal sliding bearings under conditions of elastohydrodynamic lubrication
(Emerald Group Publishing Ltd, Bingley, 2007)
Purpose - This paper aims to develop a simulating model of a journal porous metal bearing under elastohydrodynamic conditions and combined (radial, friction and thermal) load distribution and to carry out structural ...
Influence of gamma and X radiation on gas-filled surge arrester characteristics
(Ieee-Inst Electrical Electronics Engineers Inc, Piscataway, 2006)
This paper aims to find the possibility of stabilizing the gas-filled surge arrester's (GFSA) static working point in gamma- and X-radiation fields by an appropriate choice of constructive parameters. The observed effects ...
Monte Carlo calculation of x-rays deposited energy in CdZnTe detector
(Trans Tech Publications Ltd, 2007)
CdZnTe detectors have been employed in diagnostic X-ray spectroscopy. This paper presents the Monte Carlo calculation of X-ray deposited energy in a CdZnTe detector for different energies of photon beam. In incident photon ...
