Simulating Superconductors in AC Environment: Two Complemetary COMSOL Models

R. Brambilla[1] and F. Grilli[2]
[1]ENEA - Ricerca sul Sistema Elettrico S.p.A., Milano, Italy
[2]Karlsruhe Institute of Technology, Karlsruhe, Germany

In this paper we present a summary of our work on numerical modeling of superconductors with COMSOL Multiphysics®. We discuss the two models we utilized for this purpose: a 2-D model based on solving Maxwell equations and a 1-D model for thin conductors based on solving the integral ... Mehr lesen

Screening Effects in Probing the Electric Double Layer by Scanning Electrochemical Potential Microscopy

R.F. Hamou[1], P.U. Biedermann[1], A. Erbe[1], and M. Rohwerder[1]
[1]Max-Planck-Institut für Eisenforschung GmbH, Düsseldorf, Germany

A computational method is developed to study probing the electric double layer by Scanning Electrochemical Potential Microscopy. The model is based on a modified Poisson- Boltzmann equation, which takes into account steric effects. We investigated the effect of metallic apex protrusion ... Mehr lesen

Chaotic Behavior of the Airflow in a Ventilated Room

A.W.M. van Schijndel[1]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands

Chaotic systems may lead to instability, extreme sensitivity and performance reduction. Therefore it is unwanted in many cases. Due to these undesirable characteristics of chaos in practical systems, it is important to recognize such a chaotic behavior. The existence of chaos has been ... Mehr lesen

A Study of Laser Doppler Anemometer Using COMSOL Multiphysics®

I. Lancranjan[1] and C. Gavrila[2]
[1]Advanced Study Centre, National Institute for Aerospace Research “Elie Carafoli”, Bucharest, Romania
[2]Technical University of Civil Engineering Bucharest, Bucharest, Romania

Laser anemometers based on application of Doppler Effect have been developed and are used in-flight, on aircrafts for measurement of air flow parameters, mainly its speed versus the airplane. The air speed measurements are vital for safe flights. The main basic idea of Doppler techniques ... Mehr lesen

The Optical Properties of a Truncated Spherical Cavity Embedded in Gold

A. Pors[1], O. Albrektsen[2], S.I. Bozhevolnyi[2], and M. Willatzen[1]
[1]Mads Clausen Institute, University of Southern Denmark, Sønderborg, Denmark
[2]Institute of Sensors, Signals and Electrotechnics, University of Southern Denmark, Odense, Denmark

The use of plasmonic effects to dramatically enhance the electromagnetic field near the surface of a metallic nanostructured surface has grown into a large research area in the effort to take advantage of the surface enhanced field. In this paper the electromagnetic field near a nano ... Mehr lesen

COMSOL in the Academic Environment at USNA

K. Mcilhany[1], and R. Malek-Madani[2]
[1]Department of Physics U. S. Naval Academy, Annapolis, Maryland, USA
[2]Department of Mathematics, U. S. Naval Academy, Annapolis, Maryland, USA

The U.S. Naval Academy has used COMSOL as a research tool for many years. Academic usage of COMSOL for student use has only begun in the last five years. Student involvement comes in four types, course-wide usage, focused course related work, student projects and semester-long research ... Mehr lesen

Modeling the Bacterial Clearance in Capillary Network Using Coupled Stochastic-Differential and Navier-Stokes Equations

A. Atalla[1], and A. Jeremic[1]
[1]McMaster University, Hamilton, Ontario, Canada

The capillary network is a complex-interconnected structure. A single blood cell traveling from the arteriole to a venule via a capillary bed passes through, on average, 40−100 capillary segments. The cardiovascular systems responsible of delivering blood to the tissue under sufficient ... Mehr lesen

An Acoustical Finite Element Model of Perforated Elements

P. Bonfiglio[1][2] and F. Pompoli[1][2]
[1]Materiacustica S.r.l., Ferrara, Italy
[2]Engineering Department, University of Ferrara, Ferrara, Italy

The present work deals with a numerical investigation of resonating systems used for noise control applications. In literature one can find analytical models based on fluiddynamics concepts for evaluating losses occurring across the holes of the perforates. In the paper an acoustical ... Mehr lesen

Analysis of Sound Propagation in Lined Ducts by Means of a Finite Element Model

D. Borelli[1] and C. Schenone[1]
[1]DIPTEM, University of Genova, Genova, Italy

The present paper describes the results of a Finite Element Model used to analyze sound propagation in lined ducts. By means of a numerical model it was possible to predict the insertion loss inside rectangular lined ducts in a frequency range from 250 Hz to 4000 Hz. The model was ... Mehr lesen

Temperature Distribution in High Voltage Dummy Cable

G.Y. Sun[1], O. Sekula[1], and C. Albanbauer[1]
[1]Brugg Kabel AG, Brugg, Switzerland

A 2D model of coupled electricthermal application is used to calculate the temperature distribution in a high voltage dummy cable laid in free air, where no high voltage is applied. Resistive loss heats the cable while the surrounding air cools it down. The steady-state condition is ... Mehr lesen
