Modeling, Simulation, and Control of Dual Electromagnet Active Magnetic Levitation

A.K. Pi?at[1]
[1]AGH University of Science and Technology, Kraków, Poland

Introduction: The dual electromagnet configuration of Active Magnetic Levitation system (AML) where the electromagnets are locate opposite to each other, constitutes and single axis of the Active Magnetic Bearing. The same configuration can be used to test the single electromagnet AML ... En savoir plus

Experimental Validation of Model of Electro-Chemical-Mechanical Planarization (ECMP) of Copper

J. Ebert[1], S. Ghosal[1], A. Emami-Naeini[1]
[1]SC Solutions, Sunnyvale, CA, USA

This paper describes the development of a COMSOL model of Electro-Chemical-Mechanical Planarization (ECMP) that was validated with experimental data. ECMP is used for processing of semiconductor wafers. We developed a 2D model of flow of phosphoric acid solution (the electrolyte) between ... En savoir plus

Fluid Flow Analysis For Cross-Flow Around Four Cylinders Arranged In A Square Configuration

A. Dutta, P. Goyal, R.K. Singh, and K.K. Vaze
Bhabha Atomic Research Centre, Mumbai, Maharashtra, India

Cross-flow around a group of cylinders is a very common phenomenon in engineering, such as flow around heat exchanger tube arrays. The cross-flow-induced vibration might cause a reduction of equipment life and might even lead to the occurrence of severe accidents. Hence, it is necessary ... En savoir plus

Modelling Heat and Mass Transfer in Microreactor for Methanol to Hydrocarbons

P. A. Delou [1,3], V. Degirmenci [2,3],
[1] Universidade Federal do Rio de Janeiro, Rio de Janeiro, RJ, Brazil
[2] University of Warwick, Coventry, United Kingdom
[3] Queen’s University Belfast, Belfast, United Kingdom

Recently, increasing availability of natural gas, due to the shale gas, raises the attention to the conversion of methane. Methanol-to-Hydrocarbons reaction (MTH) plays an important role in this route where methanol synthesized through syngas is converted into hydrocarbons, such as ... En savoir plus

Modeling Phytoremediation by Mangroves

O. Richter[1], H. Anh Nguyen[1], V. Phuoc Nguyen[2]
[1]Institute of Geoecology, University of Technology Braunschweig, Germany
[2]Institute for Environment & Resources, HCM-City, Vietnam

Metal contaminants and organic pollutants are affecting aquatic environments in urban and industrial zones. Mangrove trees are capable of absorbing metal ions and organic pollutants. To estimate the remediation potential, a two dimensional model of water and substance flow in the soil ... En savoir plus

Improvements in the Modeling of the Self-ignition of Tetrafluoroethylene

M. Beckmann-Kluge, F. Ferrero, V. Schröder, A. Acikalin, and J. Steinbach
Federal Institute for Materials Research and Testing, Technical University, Berlin, Germany

Tetrafluoroethylene (TFE) is a gas widely employed in industry, which can under specific circumstances experience an exothermic dimerization to octafluorocyclobutane. If the heat generated by this reaction cannot be dissipated to the surroundings, the temperature inside the reactor will ... En savoir plus

Modeling Spectral Emission Phenomena in Beryllium Plasma Using COMSOL Multiphysics

C. Gavrila[1], C. P. Lungu[2], and I. Gruia[3]
[1]Technical University of Civil Engineering Bucharest, Romania
[2]National Institute for Laser, Plasma and Radiation Physics, Bucharest, Romania
[3]University of Bucharest, Faculty of Physics, Bucharest, Romania

The purpose of this paper is to present a numerical modeling of plasma phenomena in beryllium emissions using COMSOL Multiphysics software. The Beryllium films were deposited on mirror polished fine grain graphite substrates using the Thermionic Vacuum Arc (TVA) technology available at ... En savoir plus

Acoustic streaming flows in discharge lighting

T. Dreeben
Osram Sylvania, Beverly, MA, USA

Thomas Dreeben received his B.A. in Philosophy and Mathematics in 1985, and his Ph.D. in Mechanical Engineering in 1997, both from Cornell University. He has worked in automotive fuel systems at Ford Motor Company, and in turbulence at Sandia National Laboratories. He currently works in ... En savoir plus

Comsol’s New Thermoviscous Interface and Computationally Efficient Alternative Formulations for FEM

W. R. Kampinga[1], and Y. H. Wijnant[2]
[1]Reden, Hengelo, Netherlands
[2]University of Twente, Enschede, Netherlands

Three efficient alternatives to the model in COMSOL’s thermoacoustics interface are presented. The higher efficiency of these models are explained from theory and are demonstrated by means of two examples. En savoir plus

Second Order Drift Forces on "Offshore" Wave Energy Converters

L. Martinelli[1], A. Lamberti[1], and P. Ruol[2]

[1]DISTART Idraulica, Università di Bologna, Bologna, Italy
[2]IMAGE, Università di Padova, Padova, Italy

Objective of this contribution is to present a procedure for evaluating second order drift forces on floating bodies, often the most important loading component for mooring design, in case of high waves propagating in relatively shallow water depths. The non linearity associated to this ... En savoir plus
