Multiphysics Modelling of Food Dehydration during RF Exposure

R. Renshaw[1]
[1]e2v Ltd., Essex, United Kingdom

There is a requirement for an RF (Radiofrequency) industrial dryer that will be capable of dehydrating foodstuff to the correct level after the product has been fried. RF drying should actively target moisture, due to waters high dielectric properties. An industrial dryer can be ... Read More

Numerical Modelling of a Free-Burning Arc in Argon. A Tool for Understanding the Optical Mirage Effect in a TIG Welding Device

J-M. Bauchire[1], E. Langlois-Bertrand[1], and C. de Izarra[1]
[1]GREMI, CNRS, Université d’Orléans, Orléans, France

In this paper, we present the numerical modelling of a free-burning arc and its application to the understanding of optical mirage effect which could occur in a TIG (Tungsten Inert Gas) device used in welding applications. Read More

Understanding “Mutual Inductance” using COMSOL Multiphysics^®

H.A. Ghali[1] and H.A. Rahman[1]
[1]Electrical Engineering Department British University in Egypt “BUE”, El Sherouk City, Egypt

A teaching platform that could be used to help students understand concepts such as; flux linking and mutual inductance has been developed using the AC/DC Module of COMSOL Multiphysics®. This is achieved through the accurate determination of different magnetic flux density components ... Read More

A Magnetohydrodynamic Study of a Inductive MHD Generator

A. Montisci[1] and R. Pintus[1]

[1]Department of Electrical and Electronic Engineering, University of Cagliari, Cagliari, Italy

The aim of the proposed device is to overcome the typical drawbacks of MHD generators, such as the needed of a very high external magnetic field, the strong dependency of the efficiency by the temperature of the fluid, and the deterioration of the electrodes that are in contact with the ...

3D Modeling of Microwave Plasma Using Funer Model

O. Geoffroy[1] and H. Rouch[1]
[1]INOPRO, Villard de Lans, France

After previous microwave simulations done with very hard assumptions, we improve the model by using Funer model to improve prediction of plasma effects on the microwave coupling. Some parameters are still not well known and are used as adaptation parameters. An experience plan technique ... Read More

Magnetic Fields and Materials for Medical Bone Reconstruction Assisted by Advanced Finite-Element Simulations

A. Sytcheva[1] and T. Herrmannsdörfer[1]
[1]Hochfeld-Magnetlabor Dresden, Forschungszentrum Dresden-Rossendorf, Dresden, Germany

We address the use of magnetic fields, forces, and materials for medical purposes. In particular, the treatment of osteochondral lesions is aimed for. To support ongoing activities in this field of research, last advances in using Finite Element Analysis (FEA) for the simulation of ... Read More

Thin Membrane Modelling for the Electrical Stimulation of Auditory Nerve

A. Grünbaum[1], S. Petersen[1], H.W. Pau[2], and U. van Rienen[1]

[1]IEF funded by DFG Research Training Group 1505/1 Welisa, University of Rostock, Rostock, Germany
[2]Otolaryngology “Otto Körner”, University of Rostock, Rostock, Germany

Modeling of 2-5 μm thin membranes into a cochlea with a width of 2 cm is computationally. The paper is focused on two approximative methods used to overcome this problem and in addition a simple model challenging of a plate capacitor with a thin membrane of different thickness in ... Read More

Calculating Power Loss of Contactless Power Transmission Systems with Ferrite Components

S. Hanf[1] and D. Kürschner[1]
[1]Institut für Automation und Kommunikation Magdeburg, Magdeburg, Germany

In this paper a methodology for calculating loss within contactless inductive power transmission systems, resulting from hysteresis and eddy current effects, is presented. The usage of the mathematical models of Stoll and Steinmetz for the determination of core loss with COMSOL is ... Read More

COMSOL Assisted Simulation of Laser Engraving

H. Karbasi
Conestoga College, Kitchener, ON, Canada

The main purpose of this paper is to develop a proof of concept software that can simulate the geometry of engraved surfaces and can estimate the depth and width of engraved groove and associated laser parameters. For this purpose, COMSOL has been used to simulate the moving laser beam ... Read More
