Using COMSOL Multiphysics® for the Development of an Arc Synchronous Motor with a Halbach Wheel Rotor

R. Anderka[1], A. Jocas[1], A. Vasudevan[1]
[1]University of Edinburgh, United Kingdom

Hyperloop is a theoretical high-speed mass transportation system which aims to increase efficiency through the use of low-pressure tunnels and contactless propulsion. The University of Edinburgh’s Hyperloop Team (HYPED) has been selected to participate in the SpaceX Hyperloop Pod ... En savoir plus

Periodic Near-field Enhancement on Metal-Dielectric Interfacial Gratings at Optimized Azimuthal Orientation

[1]Research Laboratory of Electronics, Nanostructures Laboratory, Massachusetts Institute of Technology, Massachusetts, USA
[2]Department of Optics and Quantum Electronics, University of Szeged, Szeged, Hungary

The effect of plasmon-wavelength scaled gratings on the surface plasmon resonance is studied experimentally and theoretically. The model samples are multi-layers containing laser fabricated gratings at bimetal-polymer interfaces. Dual-angle dependent surface plasmon resonance ... En savoir plus

An Original Way of Using COMSOL Multiphysics® Application Builder to Enhance Simulation of Laser Welding

Y. A. Mayi¹, M. Dal¹, P. Peyre¹, M. Bellet², C. Metton³, C. Moriconi³, R. Fabbro¹
¹Laboratoire PIMM, Arts et Metiers, Paris, France
²CEMEF, MINES ParisTech, Sophia Antipolis, France
³Safran Additive Manufacturing, Paris, France

The present work introduces a new methodology, based on COMSOL Multiphysics® Application Builder, to account for the “beam trapping” effect in multiphysical modelling of laser welding. Incident intensities involved in laser welding processes are high enough to induce material ... En savoir plus

The Proximity Effect: A Comparison of COMSOL Multiphysics® and Analytic Solutions

C. Cooke[1], L. Shatz[2]
[1]Massachusetts Institute of Technology, USA
[2]Suffolk University, USA

An important attribute for numerical simulations is to provide accurate quantified solution values. Thus it is useful to find complex problems with analytic solutions to confirm the numerical results obtained from software. The well-known proximity effect causes a redistribution of ...

Growth of Transient Quantum Mechanical Dirac Wave Functions Through Electric or Magnetic Fields

A. Kalinowski[1]
[1]Consultant, USA

INTRODUCTION: The Dirac equation is employed in particle physics and historically gave the first combined unification of quantum mechanics and relativity theory by introducing a four component wave function Ψn n=1…4. This wave function describes the behavior of fermion type particles (e ... En savoir plus

Simulation of Dynamic Thermal Fields Assisting DMLS Additive Manufacturing of Biocompatible Ti-Alloy

E. Lacatus [1], G. C. Alecu [2], M. Sopronyi [3],
[1] Polytechnic University of Bucharest, Bucharest, Romania
[2] Groupe Renault, Bucharest, Romania
[3] National Institute for Laser, Plasma and Radiation Physics (INFLPR), Magurele, Romania

For the complex 3D biocompatible metallic parts, with high level of customization, used in medical prosthesis and implants Direct Metal Laser Sintering (DMLS) and Selective Laser Melting (SLM) are the most common Additive Manufacturing technologies used nowadays. However, both ... En savoir plus

Frequency Dependent UEP Signatures of Naval Vessels Modeled by a Current Dipole

C. Broecheler [1], Ch. Thiel [1], A. Rennings [1], F. Ludwar [2], J. Doose [2], D. Erni [1],
[1] General and Theoretical Electrical Enigneering (ATE), University of Duisburg-Essen, and CENIDE-Center for Nanointegration Duisburg-Essen, Duisburg, Germany
[2] Technical Center for Ships and Naval Weapons, Naval Technology and Research (WTD71), Eckernförde, Germany

The underwater electric potential (UEP) signature of naval vessels poses a severe threat as it is detectable by advanced sea mines. The signature depends also on the environment, mainly the water-seabed interface, leading in summary to the total UEP signature. The seabed has a ... En savoir plus

Development of Eddy Current Probe using FEM for Matte Level Detection in Pyrometallurgical Furnaces

A. Saleem [1], P. R. Underhill [1], D. Chataway [2], T. Gerritsen [2], A. Sadri [2], T. W. Krause [1],
[1] Department of Physics and Space Science, Royal Military College of Canada, Kingston, ON, Canada
[2] Hatch Ltd., Mississauga, ON, Canada

Pyrometallurgical furnaces are used to produce metals such as copper, nickel and platinum by the smelting process. During smelting, the undesired material components are separated from the desired metal resulting in the formation of a slag and matte/metal phase. The slag phase ... En savoir plus

EMC Simulation Using Source Reconstruction

A. Bergqvist [1], P. Jacobsson [1],
[1] Volvo Cars, Gothenburg, Sweden

Electromagnetic compatibility (EMC) is a growing issue in cars due to the increase in electrification of vehicles. Simulations can be useful for predicting issues at an early stage in the development cycle. This includes investigating EM stray fields that various components generate and ... En savoir plus
