Experimental Observation and Numerical Prediction of Induction Heating in a Graphite Test Article

T.A. Jankowski[1], D.P. Johnson[1], J.D. Jurney[1], J.E. Freer[1], L.M. Dougherty[1], and S.A. Stout[1]

[1]Los Alamos National Laboratory, Los Alamos, New Mexico, USA

The induction heating coils used in the plutonium casting furnaces at the Los Alamos National Laboratory are studied here. A cylindrical graphite test article has been built, instrumented with thermocouples, and heated in the induction coil that is normally used to preheat the molds ... En savoir plus

Bioheat Dissipation of a Implantable Brain-Machine Interface

J. M. Herrera Morales [1],
[1] Wyss Center for Bio and Neuroengineering, Switzerland

Brain-Machine Interfaces (BMI) provide a direct communication link between brain and external devices such as speech synthesizers and robotic prosthesis to restore speech and movement in persons affected by Spinal Cord Injuries or neurodegenerative diseases such as Amyotrophic Lateral ...

Modeling of High-Speed PCB-Interconnects, Vias and Connectors for the Estimation of SI-Losses

A. K. Palit [1],
[1] ZF-Lemförder Electronic GmbH (ZF-Friedrichshafen AG. Group), Germany

Estimation of both single-ended (SE) and differential-pair (DP) impedances of high-speed PCB-traces/interconnects, vias and connectors is very important for the high-speed PCB (layout) design. This is because, the mismatch in line-impedances/improper line-termination results in a ... En savoir plus

Laser-Material Interaction Modeling using the COMSOL Multiphysics® software

E. C. Chevallier [1], V. Bruyère [1], P. Namy [1],
[1] SIMTEC, Grenoble, France

Surface engineering is a key technology used in a wide range of sectors in industry. Among other techniques, it involves adding functionality to a surface. This can be performed by creating a specific topography to a surface using laser texturing. The objective of the work presented in ... En savoir plus

Investigating a Tensor Formulation to describe the Magnetic Structure of Soft Magnetic Materials

O. Maloberti [1], M. Nesser [2], E. Salloum [2], J. Fortin [2], S. Panier [2], P. Dassonvalle [1], C. Pineau [3], M. Caruso [4], J-P. Birat [3], I. Tolleneer [4],
[1] ESIEE Amiens, France
[2] UPJV-LTI, France
[3] IRT-M2P, France
[4] CRM Group, France

Most of existing material representations [1], even including the dynamic hysteresis and iron losses [2], ignore local microscopic non-uniformities. These concern the magnetic structure (domains and walls [3]) and are mainly due to surface effects, anisotropy and exchange [4]. One ... En savoir plus

Simulation of an ECT Sensor to Inspect the Reinforcement of Concrete Structures

N. P. de Alcantara Jr. [1], L. Gonçalves Jr. [1],
[1] São Paulo State University - Unesp, Bauru, SP, Brazil

The paper describes the use of COMSOL Multiphysics to simulate an ECT (Eddy Current Testing) sensor, designed to inspect the elements of the reinforcement of concrete structures. The paper describes the steps for the COMSOL simulation, and analyze the results for three configurations ... En savoir plus

An App for Calculating the Electric Field outside Electrical Installations

N. Lavesson [1],
[1] ABB Corporate Research, Västerås, Sweden

This paper describes the implementation of an app for calculating low frequency electric fields outside electrical installations. The app is based on a 2D parametric geometry chosen in such a way that it approximates a large class of electrical installations, which consist of a tower or ... En savoir plus
