Analyzing Muffler Performance Using the Transfer Matrix Method

K. Andersen
Dinex Emission Technology A/S, Middelfart, Denmark

Exhaust noise must meet legislation targets, customer expectations and cost reduction which call for design optimization of the exhaust systems in the design phase. One solution is to use 3 dimensional linear pressure acoustics and calculate the transfer matrix of the muffler. The ... En savoir plus

Simulation of Piezoelectric Transformers with COMSOL

T. Andersen[1], M. A. E. Andersen[1], O. C. Thomsen[1]
[1]DTU Elektro, Technical University of Denmark, Kgs. Lyngby, Denmark

In this work COMSOL is utilized to obtain the Mason lumped parameter model for a piezoelectric transformer (PT) design. The Mason lumped parameters are relevant in the design process of power converters. The magnitude of the impedance is simulated for a specific interleaved multilayer ... En savoir plus

Nanoporous Silicon Structures for Toxin Detection

H. Ghosh[1], C. R. Chaudhuri[1]
[1]Department of Electronics and Telecommunication, BESUS, Howrah, West Bengal, India

In this project, we are aiming towards the development of an impedimetric biosensor based on nanoporous silicon structures for the detection of small molecular size and low weight food toxins (like Aflatoxin). Existing sensors for such toxin detection fail to achieve high sensitivity ... En savoir plus

Analyzing Electromagnetic Modes of Integrated Busbars Implemented as Printed Circuit Boards (PCB)

A. Pokryvailo [1],
[1] Spellman High Voltage Electronics Corp., Hauppauge, NY, USA

This report addresses design of a PCB intended for use as a busbar integrated with multiple DC-link (rail) capacitors in a high power inverter. The geometry and current ratings are typical of a 50 kW unit operating at 60kHz in an intermittent mode. First, circuit aspects are analyzed. ... En savoir plus

Time-Harmonic Modeling of Squirrel-Cage Induction Motors: A Circuit-Field Coupled Approach

R. Escarela-Perez[1], E. Melgoza[2], and E. Campero-Littlewood[1]

[1]Universidad Autonoma Metropolitana - Azcapotzalco, Departamento de Energia, México, D.F., Mexico
[2]Instituto Tecnologico de Morelia, Morelia, Mich., C.P., Mexico

Finite element modeling of three-phase induction machines requires the solution of coupled circuit and field equations. This work aims to solve this problem using a strong coupling approach. This work includes circuit field coupling and proper air-gap meshing, using the AC/DC Module of ... En savoir plus

Expanding Your Materials Horizons

R. Pryor[1]
[1]Pryor Knowledge Systems, Inc. (COMSOL Certified Consultant), Bloomfield Hills, Michigan, USA

Materials and their related properties are intrinsically fundamental to the creation, development and solution of viable exploratory models when using numerical analysis software. In many cases, simply determining the location, availability and relative accuracy of the necessary material ... En savoir plus

Microstimulation in The Brain: Does Microdialysis Inuence the Activated Volume of Tissue?

D. Krapohl[1][3], S. Loeffler[2], A. Moser[2], and U.G.Hofmann[1]

[1]Institute for Signalprocessing, University of Luebeck, Lübeck, Germany
[2]Institute for Neurology, University of Luebeck, Lübeck, Germany
[3]Department of Information Technology and Media, Mid Sweden University, Sundsvall, Sweden

Deep Brain Stimulation (DBS) has been established as an effective treatment for Parkinson's disease and other movement disorders. The stimulation is currently administered using tetrode-macroelectrodes that target the Subthalamic Nucleus (STN). This often leads to side effects which bias ... En savoir plus

SLIET, Longowal, Sangrur
Punjab, India

Curved cone corrugated ground plane conical antenna has been designed and analyzed using Finite Element Method. In this paper, we introduce a novel Curved cone corrugated ground plane conical antenna for ultra-wideband (UWB) applications. The antenna is composed of curved cone with ... En savoir plus

Wireless Interaction of Neighboring Two Arm Archimedes Spiral Coils in the RF Electromagnet Range

A. Kalinowski[1]
[1]Naval Undersea Warfare Center/ Division Newport, Newport, RI, USA

The paper addresses a class of problems for modeling and consequently simulating the electromagnetic field radiation pattern from two arms Archimedes spiral coils. The frequency spatial wavelengths relative to the coil dimensions are in a range where the electromagnetic Maxwell’s ... En savoir plus

Calculation of Cable Parameters for Different Cable Shapes

H. Lorenzen[1], J. Timmerberg[1], and S. Mylvaganam[2]
[1]Department of Electrical Engineering, UAS OOW, Wilhelmshaven, Germany
[2]Department Technology/Engineering, Telemark University College, Porsgrunn, Norway

Efforts involving simulation of transmission line networks necessitate the accurate values of the parameters of the lines. In this paper, as an attempt in estimating such parameters, the parameters of high voltage asymmetric power lines are calculated. In the process of estimation, the ... En savoir plus
