Group theoretical formulation of quadrilateral and hexahedral isoparametric finite elements
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
The group supermatrix procedure, developed by Zlokovic, is applied for derivation of stiffness matrices of quadrilateral and hexahedral isoparametric finite elements using the symmetry groups C-2v and D-2h respectively. ...
Design update, thermal and fluid dynamic analyses of the EU-HCPB TBM in vertical arrangement
(Elsevier Science Sa, Lausanne, 2009)
In the frame of the activities of the EU Breeder Blanket Programme and of the Test Blanket Working Group of ITER, the Helium Cooled Pebble Bed Test Blanket Module (HCPB TBM) is developed in Forschungszentrum Karlsruhe (FZK) ...
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 ...
An experimental study of temperature of burning coal particle in fluidized bed
(Amer Chemical Soc, Washington, 2006)
The purpose of this study was to investigate the temperature of coal particle during combustion in fluidized bed (FB). It is necessary to know the coal particle temperature in order to predict kinetics of chemical reactions ...
Numerical Prediction of Pulverized Coal Flame in Utility Boiler Furnaces
(Amer Chemical Soc, Washington, 2009)
In optimization of a utility boiler furnace operation, special attention is given to the flame geometry and position. As an illustration of possibilities for application of mathematical prediction and numerical experiment ...
The validity of the general similarity law for electrical breakdown of gases
(IOP Publishing Ltd, Bristol, 2006)
This paper investigates the validity of the similarity law in cases of dc and pulse breakdown of gases. Geometrically similar systems insulated with SF6 gas were used during experiments. It is shown that the similarity law ...
Resonant generation of the rectification electric mode in suddenly created cold lossless magnetized plasma. transversal propagation
(Amer Inst Physics, Melville, 2009)
The nonlinear transformation of the linearly polarized source electromagnetic wave into electron and electromagnetic plasma oscillations, stationary (rectification and space-varying ) modes, and traveling electron and ...
Immobilization of lipase from Candida rugosa on Eupergit (R) supports by covalent attachment
(Elsevier, Amsterdam, 2006)
The present study compares the results of three different covalent immobilization methods employed for immobilization of lipase from Candida rugosa on Eupergit C supports with respect to enzyme loadings, activities and ...
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 ...
A review of automated feature recognition with rule-based pattern recognition
(Elsevier, Amsterdam, 2008)
Automated feature recognition (AFR) has provided the greatest contribution to fully automated CAPP system development. The objective of this paper is to review various approaches for solving three major AFR problems: (i) ...
