Inductance of Magnetic Plated Wires as a Function of Frequency and Plating Thickness

T. Graf[1], O. Schälli[1], A. Furrer[1], and P. Marty[1]

[1]Technik und Architektur, Hochschule Luzern, Horw, Switzerland

This paper analyzes the magnetic behavior of electroplated wires. For this purpose the resistance and inductance of single turn loops and coils have been simulated and measured. The measurement is delicate due to the influence of a stray capacitance. We show that the quality factor of ... Read More

A Novel FEM Method for Predicting Thermoacoustic Combustion Instability

G. Campa[1] and S.M. Camporeale[1]
[1]DIMEG, Politecnico di Bari, Bari, Italy

Modern gas turbines suffer of the phenomenon of combustion instability, also known as “humming”. The main origin of the instability is considered to be related to the interaction between acoustic waves and fluctuations of the heat released by the flame. This paper presents a ... Read More

Accuracy of Fully Coupled Loudspeaker Simulation Using COMSOL

M. Hedges[1][2] and Y.W. Lam[1]
[1]Acoustics Research Centre, School of Computing, Science & Engineering, University of Salford, Salford, United Kingdom
[2]Monitor Audio Ltd., Rayleigh, Essex, United Kingdom

Loudspeaker simulation is used to inform the designer as to the performance of a design. In recent years the Finite Element Method (FEM) has been used to model the mechanical and acoustical attributes of a loudspeaker with varying success. This paper shows how a model that incorporates ... Read More

Model Development and Implementation of a Membrane Shift Reactor

J. Völler[1], M. Follmann[1], C. Bayer[1], and T. Melin[1]

[1]AVT Chemical Process Engineering, RWTH Aachen University, Aachen, Germany

Low temperature fuel cells require hydrogen of high purity for electricity production to avoid catalyst poisoning. To purify hydrogenrich flue gases from hydrocarbon steam reforming membrane shift reactors with a metal membranes may be utilized. A model of a tubular membrane shift ... Read More

A Model for High Temperature Inductive Heating

S.A. Halvorsen[1]
[1]Teknova AS, Kristiansand, Norway

COMSOL Multiphysics has been applied to develop a model for inductive heating. A coarse, lumped model of the interior of a high temperature reactor is coupled to finite element models for the electromagnetic field, the temperature distribution outside the reactor, and mechanical stresses ...

Simulation of the Turbulent Flow in HEV Static Mixers : Mixing of Ethanol with Gasoline

A. Eissa[1]
[1]Department of Chemical Engineering, Cairo University, Giza, Egypt

Mixing is a typical unit operation that occurs almost in all chemical industries. Static – alternatively termed motionless – mixers are being widely used due to their low power consumption, low capital investment, minimal maintenance costs and versatility. The traditional helical mixing ... Read More

Elastoplastic Models of the Interaction between Active Fronts of the Southern Alps and Dinarides (NE Italy and NW Slovenia)

M. Coccia[1], E. Carminati[1], F. Rolandone[2], M. Battaglia[1], D. Zuliani[3], and P. Fabris[3]
[1]Università La Sapienza, Roma, Italy
[2]Université Pierre et Marie Curie, Paris, France
[3]Centro Ricerche Sismologiche, Udine, Italy

We use GPS measurements and Finite Element analysis to investigate strain accumulation in the interaction between active fronts of the Southern Alps and Dinarides at the northern edge of the Adriatic micro-plate. We develop a three dimensional model of the area taking into account the ... Read More

On the Numerical Modeling of Elastic Resonant Acoustic Scatterers

V. Romero-García[1], A. Krynkin[2], J.V. Sánchez-Pérez[1], S. Castiñeira-Ibáñez[3], and L.M. Garcia-Raffi[4]

[3]Depto. Física Aplicada, Universidad Politécnica de Valencia, Valencia, Spain
[4]Instituto Universitario de Matemática Pura y Aplicada, Universidad Politécnica de Valencia, Valencia, Spain

The elastic and geometrical properties of Low Density Polyethylene (LDPE) foam are used in this paper to improve the attenuation properties of periodic arrangements of acoustic scatterers known as Sonic Crystals (SCs). A specific recycled profile of LDPE foam is used as elastic-acoustic ... Read More

Finite Element Model of a Complex Glass Forming Process as a Tool for Control Optimization

F. Sawo[1] and T. Bernard[1]
[1]Fraunhofer Institute for Information and Data Processing IITB, Karlsruhe, Germany

This paper addresses the modeling of a complex glass forming process as an example of a complex, nonlinear distributed parameter system. The system is modeled by a fluid dynamics approach, which means that the forming is regarded as a fluid with free surfaces. Here, the coupling of the ... Read More

Designing Polymer Thick Film Intracranial Electrodes for use in Intra-Operative MRI Setting.

G. Bonmassar[1], and A. Golby[2]
[1]AA. Martinos Center, Massachusetts General Hospital, Charlestown, Massachusetts, USA
[2]Department of Neurosurgery, Brigham and Women’s Hospital, Boston, Massachusetts, USA

A new type of MRI compatible intracranial electrode based on Polymer Thick Film (PTF) is presented and studied using COMSOL Multiphysics. The geometry considered was a two-dimensional cross section cut of 5 mm thick electrodes with 5 cm leads on top of a 2×10 cm slab representing ... Read More
