Simulation of Dielectric Barrier Discharge Lamp Coupled to the External Electrical Circuit

A. El-Deib[1], F. Dawson[1], S. Bhosle[2], D. Buso[2], and G. Zissis[2]
[1]University of Toronto, Toronto, Ontario, Canada
[2]LAPLACE-University of Toulouse, Toulouse, France

This work uses COMSOL to simulate the Dielectric Barrier Discharge (DBD) lamp coupled to the external electrical circuit. The coupled system is modeled to capture the effect of the electrical parasitic elements on the efficiency of the DBD which is more realistic as compared to previous ... En savoir plus

Gate Control of Single-Electron Spins in GaAs/AlGaAs Semiconductor Quantum Dot

S. Prabhakar and J. Raynolds
College of NanoScale Science and Engineering, University at Albany, Albany, NY, USA

Non-charge-based logic is the notion that an electron can be trapped and its spin manipulated through application of gate voltages. Numerical simulations of Spin Single Electron Transistors (SSET) at University at Albany, aimed at practical development of post-CMOS concepts and devices ... En savoir plus

A Time Dependent Dielectric Breakdown (TDDB) Model for Field Accelerated Low-K Breakdown Due To Copper Ions

R. Achanta, J. Plawsky, and W. Gill
Department of Chemical and Biological Engineering, Rensselaer Polytechnic Institute, Troy, NY, USA

We have simulated the copper ion concentration and internal electric field profiles in a dielectric material by solving the transient continuity/Poisson equations using COMSOL Multiphysics. We have shown that failure of dielectrics can be modeled if we assume that failure in Cu/SiO2/Si ... En savoir plus

Stochastic Approach in Approximation of the Transient Plasma Sheath Behavior in FEM

J. Brcka
TEL US Holdings, Inc., Albany, NY, USA

Recently, the advanced plasma tools have been using very high frequency power sources (>100 MHz) and their combination to excite plasma utilized in semiconductor technology. This approach is evoking the regimes that are less understood and currently a subject to many studies and ... En savoir plus

Acoustic-Structure Interaction Simulation of a Differential Phase Sensor

J. H. Lee[1]
[1]Department of Mechanical Engineering, American University of Sharjah, Sharjah, UAE

The idea of application as a hearing device based on a parasitoid fly, Ormia ochracea has been studied extensively recently. This paper addresses another possible application as an underwater directional sensor. In order to study the feasibility of the application, it is necessary to ... En savoir plus

Models of Simple Iron Cored Electromagnets

J. Mammadov[1]
[1]University of Manchester, Manchester, UK

This report mainly discusses the implementation and results of a project proposal, “Modelling using Finite Element Methods”. The report is devoted to implementation, which is a model of an electromagnet. The software tool that is used to model the electromagnet is COMSOL Multiphysics®, a ... En savoir plus

Energy Pile Simulation – an Application of THM-Modeling

E. Holzbecher[1]
[1]Georg-August University, Göttingen, Germany

Energy piles, i.e. heat exchangers located within the foundation piles of buildings, are used for heating of cooling purposes. Although the absolute values of deformations and temperature gradients are low or moderate, the entire setting can be influenced by thermo-hydro-mechanical ... En savoir plus

COMSOL Multiphysics® Simulation of Energy Conversion and Storage Concepts Based on Oxide Crystals

C. Cherkouk[1], M. Zschornak[1], J. Hanzig[1], M. Nentwich[1], F. Meutzner[1], M. Urena[1], T. Leisegang[2], D. C. Meyer[1]
[1]Institute of Experimental Physics, Technische Universität Bergakademie, Freiberg, Germany
[2]Fraunhofer-Technologiezentrum, Freiberg, Germany

A mathematical model based on a finite element method (FEM) is presented as an initial approach for a system converting waste heat energy into chemical energy. This system consists of a pyroelectric LiNbO3 plate placed into a cylinder which undergoes a laminar water flow with an ... En savoir plus

Role of the Diffusion Current in Nonequilibrium Modeling of Welding Arcs

M. Baeva[1]
[1]INP Greifswald e.V., Greifswald, Germany

2D self-consistent nonequilibrium model of a free-burning arc in argon has been developed. The model is based on the COMSOL Multiphysics® platform and describes in a self-consistent manner the fluid dynamics, the heat transfer, the magneto-electrodynamics, and species conservation. The ...
