2D Extraction of Open-Circuit Impedances of Three-Phase Transformers

R. Escarela-Perez[1], E.A. Gutierrez-Rodriguez[2], J.C. Olivares-Galvan[1], M.S. Esparza-González, and E. Campero-Littlewood[1]

[1]Departamento de Energia, Universidad Autonoma Metropolitana - Azcapotzalco, Mexico D.F., Mexico
[2]Instituto Tecnologico de Aguscalientes, Aguascalientes, Mexico

This work is concerned with the study of the asymmetrical phenomenon observed in three-phase transformers during the standard short-circuit test. The purpose of our work is to see if the asymmetric measurements can be predicted with the use of 2D finite-element models. To this end, we ... Mehr lesen

Using Microwaves for Extracting Water From the Moon

Edwin Ethridge
Senior Materials Scientist, NASA Marshall Space Flight Center

A scientific hypothesis states that cryogenic trapped water is just under the surface of lunar soil at the poles in permanently shadowed craters. Microwave energy can be used to efficiently extract this water from permafrost. COMSOL permits calculation of the heating of simulated lunar ... Mehr lesen

Periodic Near-field Enhancement on Metal-Dielectric Interfacial Gratings at Optimized Azimuthal Orientation

M. Csete[1,2], X. Hu[1], A. Sipos[2], A. Szalai[2], A. Mathesz[2], and K. Berggren[1]

[2]Department of Optics and Quantum Electronics, University of Szeged, Szeged, Hungary

The effect of plasmon-wavelength scaled gratings on the surface plasmon resonance is studied experimentally and theoretically. The model samples are multi-layers containing laser fabricated gratings at bimetal-polymer interfaces. Dual-angle dependent surface plasmon resonance ... Mehr lesen

An Efficient Finite Element Analysis on an RF Structure Used to Evaluate the Effect of Microwave Radiation on Uveal Melanoma Cells

A. Dulipovici[1], D. Roman[2], I. Stiharu[2], and V. Nerguizian[1]

[1]École de technologie supérieure, Montreal, Quebec, Canada
[2]Concordia University, Montreal, Quebec, Canada

The use of Microwave/RF energy on cancer cells is explored for tumor ablation using medium power level ranging between a few Watts to about 50 Watts. In this research, low power levels, less than 100 mWatt, are used to evaluate the effect of this energy on Uveal melanoma cells by ... Mehr lesen

Fast Computation of Capacitance Matrix and Potential Distribution for Multiconductor in Non-Homogenous Multilayered Dielectric Media

S.M. Musa[1], and M.N.O. Sadiku[1]

[1]Prairie View A&M University Networking Academy, Prairie View, Texas, USA

This paper presents the fast computational and modeling of multiconductor transmission lines interconnect in non-homogenous multilayered dielectric media using the finite element method (FEM). We illustrate the potential distribution of the multiconductor transmission lines for the ... Mehr lesen

Finite Element Modeling of Transient Eddy Currents in Multilayer Aluminum Structures

V. Babbar[1], and T. Krause[1]

[1]Department of Physics, Royal Military College of Canada, Kingston, Ontario, Canada

Transient eddy current (TEC) technique is being developed for detection of flaws located at depth within multilayer aluminum structures. The present work involves finite element modeling using COMSOL Multiphysics software to simulate different types of probes by changing some of these ... Mehr lesen

Designing a Current Injection Tool for Logging While Drilling

B. Oetiker[1], B. Friedman[1], and H.E. Hall Jr.[1]

[1]Department of Physics, Sam Houston State University, Huntsville, Texas, USA

High-resolution imaging is useful in oil and gas exploration to identify producing fractures that can be in the millimeter thickness range. In principle, high-resolution imaging maybe achieved using “current injection” to measure the electrical conductivity of the formation. Two current ... Mehr lesen

Development of an On-Line Wall-Fouling Sensor for Pipeline Transportation of Heavy Oil-Water Mixtures

S. Rushd[1], and R.S. Sanders[1]
[1]Chemical & Materials Engineering Department, University of Alberta, Edmonton, AB, Canada

A beneficial method for transporting highly viscous hydrocarbons (e.g. heavy oil and bitumen) through a pipeline is known as Lubricated Pipe Flow (LPF). A major challenge for this technology is flow instability caused by the formation of a wall-coating of oil or the thinning and/or loss ... Mehr lesen
