Simulation of the Impedance Response of Materials with More Than One Electrical Path

R. A. Gerhardt [1], Y. Jin [1],
[1] Georgia Institute of Technology, Atlanta, GA, USA

Introduction Polycrystalline single phase materials often display electrical properties that are a function of their grain size. Impedance spectroscopy, an alternating current technique is ideal for detecting the presence of more than one current path and has been used for many years ... 詳細を見る

Extraction of COM Parameters and Quality Factor of One Port SAW Resonator Using FEM Based Simulation

A. K. Namdeo[1], H. B. Nemade[1]
[1]Department of Electronics and Electrical Engineering, Indian Institute of Technology Guwahati, Assam, India

The paper presents a method of extraction of coupling of modes (COM) parameters for a one port surface acoustic wave (SAW) resonator from the results of finite element analysis in COMSOL Multiphysics®. The COM parameters calculated are electromechanical coupling coefficient, reflection ... 詳細を見る

Optimum Design for Magneto-Rheological Brake Using COMSOL Multiphysics® Software

J. Thanikachalam[1], P. Nagaraj[1]
[1]Mepco Schlenk Engineering College, Sivakasi, Tamil Nadu, India

The Automotive industry has now become a technology of “Drive by Wire”. This technology is used to replace the conventional mechanical system by electromechanical system which is able to perform the same tasks faster, more reliably and accurately. The problems with the traditional ... 詳細を見る

Commercial Special Fibers for Sensing Applications

G. Latha[1], P. Nair[1]
[1]SSN College of Engineering, Chennai, Tamil Nadu, India

In a solid core PCF, structural parameters and the number of rings in the cladding region decide confinement losses, dispersion coefficients as well as bending losses. This paper evaluates some of commercially available solid core photonic crystal fibers. The dispersion coefficients and ... 詳細を見る

COMSOL Multiphysics® Models Combined with Experiments to Teach PID Controller Tuning

W. Clark[1]
[1]Chemical Engineering Department, Worcester Polytechnic Institute, Worcester, MA, USA

A laboratory exercise to learn PID controller tuning can be time consuming and taxing on the equipment. A purely equation-based, virtual controller tuning exercise might not seem relevant to real world processes. We have combined a physical process with a COMSOL Multiphysics model to ... 詳細を見る

Erik Birgersson[1]

[1]Department of Chemical and Biomolecular Engineering, National University of Singapore, Singapore, Singapore

This presentation gives an account of how COMSOL Multiphysics® software has helped to accelerate research and development. It has been used to simulate energy systems such as fuel cells, biomedical systems such as hydrogels and human skin, and monolithic catalytic converters. Each of ... 詳細を見る

Water Quality Model for Brewster Lake

Z. Aljobeh[1], G. Argueta[1]
[1]Valparaiso University, Valparaiso, IN, USA

A numerical model was developed to make spatial and temporal predictions of the water quality for Brewster Lake, located in southwestern Michigan. The model considers the hydrodynamics of the lake, hydrologic conditions, physical, chemical and biochemical processes that take place in the ... 詳細を見る

S. Titarenko[1]
[1]University of Leeds, Leeds, United Kingdom

Nowadays all branches in modern science and industry tend to solve ever complicating problems. As the result the computational time increases considerably and it become very important to reduce the processing time and use available resources more efficiently. Parallelizing problem proves ... 詳細を見る

Dynamic Characterization and Mechanical Simulation of Cantilevers for Electromechanical Vibration Energy Harvesting

N. Alcheick[1], H. Nesser[1], H. Debeda[1], C. Ayela[1], I. Dufour [1]
[1]Univ. Bordeaux, IMS Lab, Pessac, France

Energy harvesting from ambient vibrations has become an interesting topic for powering wireless sensor networks. Resonant microdevices based on MEMS have become of central importance at low frequency. The power produced at resonance is at least one order of magnitude larger than off ... 詳細を見る

The Influence of Core Shape and Material Nonlinearities to Corner Losses of Inductive Element

M. Puskarczyk[1], B. Jamieson[1], W. Jurczak[1]
[1]ABB Corporate Research Center, Kraków, Poland

The effects of sharp corners on the flux distribution in a ferromagnetic core are modeled using COMSOL Multiphysics® to determine the time-domain flux density for an applied field which is uniform in the non-corner section of the core. The frequency spectrum of the flux distribution is ... 詳細を見る
