Assessing COMSOL Performances on Typical Problems Faced by Turbo-Generator Manufacturers

E.A. Badea[1], J. Oesterheld[1], S. Friedel[2], M. Olsson[3]
[1]Alstom Schweiz, Birr, Switzerland
[2]COMSOL, Zürich, Switzerland
[3]COMSOL, Stockholm, Sweden

Multiphysics processes manifest in turbo-generators due to the leakage electromagnetic field of the stator and rotor end winding and its associated effects at machine frontal end. Such processes are a compilation of coupled phenomena having different electromagnetic, thermal, fluid flow ... Read More

Ercan Dede currently works as a Principal Scientist for the Toyota Research Institute of North America, where his research involves the multiphysics simulation and optimization of electromechanical systems for advanced vehicle applications. Dr. Dede received his Ph.D. and B.S., ... Read More

Investigations on Polarization Losses in Planar Solid Oxide Fuel Cells

S. T. Aruna [1], S. Senthil Kumar [1], A. Iyer [1], B. ShriPrakash [1]
[1] CSIR-National Aerospace Laboratories, Bangalore, Karnataka, India

In recent years, various configurations of planar Solid Oxide Fuel Cells (SOFC) have been developed for enhancing its performance. The objective of these efforts are centered on reducing polarization losses (also referred as "overpotential") by optimizing the structure and properties of ... Read More

Electrostatic Fluid Structure Interaction (EFSI) on the Huygens Experiment

R. Godard [1], J. de Boer[1], N. Ibrahim[2], and G. Molina-Cuberos[3]
[1]Royal Military College of Canada, Kingston, ON, Canada
[2]University of Toronto, Toronto, ON, Canada
[3]Campus Espinardo, Murcia, Spain

The Huygens Atmospheric Structure Instrument (HASI) was designed to characterize the physical properties of the lower atmosphere and surface of Titan, the planet-size moon of Saturn. The Relaxation Probe (RP) sensor on the Huygens probe, determined the electrical conductivity in the ... Read More

Acoustic Field Comparison of High Intensity Focused Ultrasound Using Experimental Characterization and Finite Element Simulation

J. L. Teja[1], A. Vera[1], L. Leija[1]
[1]Department of Electrical Engineering, Cinvestav-IPN, Mexico D.F., Mexico

High Intensity Focused Ultrasound (HIFU) is used as a noninvasive technique of tissue heating and ablation for different medical treatments. This paper presents a quantitative comparison of HIFU acoustic fields experimentally obtained versus simulated acoustic fields. Acoustic field ... Read More

Simulation of Electro-Thermal Transients in Superconducting Accelerator Magnets

L. Bortot [1], M. Maciejewski [2], M. Prioli [1], B. Auchmann [3],
[1] CERN, Geneva, Switzerland
[2] CERN, Geneva, Switzerland; Lodz University of Technology, Lodz, Poland
[3] CERN, Geneva, Switzerland; Paul Scherrer Institute, Zurich, Switzerland

The paper presents the application of COMSOL Multiphysics® software to the modelling of superconducting accelerator magnets. A 2D magneto-thermal model is developed, using an equivalent magnetization formulation to take into account the eddy-currents’ effects. Due to the model ... Read More

Loudspeaker Simulations in a Car Cabin

F. Malbos [1], M. Bogdanski [2], M. Strauss [2]
[1] Harman France, Paris, France
[2] Harman Becker Automotive Systems, Straubing, Germany

The goal of this study is to improve the audio simulation accuracy for automotive applications. COMSOL® Acoustics Module and LiveLink™ for MATLAB® were used to simulate the sound pressure generated by a loudspeaker in a car cabin. A comparison between simulated and measured sound ... Read More

Thermo-Mechanical Analysis and Fatigue Life Prediction for an Electronic Surface-Mount Device (SMD)

G. Petrone [1], C. Barbagallo [1], M. Scionti [1],
[1] BE CAE and Test, Catania, Italy

Electronic devices produce a very high rate of specific heat with respect to their dimensions. Exceeding in maximum safe operating temperature means strong reduction of efficiency, reliability and lifetime. In addition, electronic devices are subjected to periodical thermal loading. ... Read More
