This poster presents the electric field flowing through an insulated cable due to a high frequency voltage pulse in the presence of water trees. Mehr lesen

Thermal Analysis of Dry Type Power Transformer under Effect of Linear and Nonlinear Loads

R. G. Mafra [1],
[1] Universidade Federal de Itajubá, Itajubá, MG, Brazil

The thermal performance of the dry type power transformers is directly connected to the internal heat source caused by electrical losses. Thus, it is necessary to evaluate the temperatures reached by the transformer core to ensure optimum operation. This paper presents a detailed ... Mehr lesen

Design of Dielectrophoretic Cell Traps in Microfluidics Devices Using COMSOL Multiphysics® Software

L. Velmanickam [1], K. Nawarathna [1],
[1] Department of Electrical and Computer Engineering, North Dakota State University, Fargo, ND, USA

The isolation of target cells from biological samples such as serum, urine or blood in high-throughput manner without contamination with other cells is the starting point of developing effective therapy for many diseases. Currently available methods for cell isolation/separation require ... Mehr lesen

Predicting Critical Current as a Function of Magnetic Field in High-Temperature Superconductors

J. Doody [1], P. Michael [1], R. Vieria [1], W. Beck [1], L. Zhou [1], J. Irby [1],
[1] Massachusetts Institute of Technology - Plasma Science and Fusion Center, Cambridge, MA, USA

REBCO tapes belong to a class of high-temperature superconductors (HTS) that can be superconducting at liquid nitrogen temperatures (77K) as opposed to typical superconductors such as Nb3Sn which need to operate at liquid helium temperatures (4K). One important aspect of designing a ... Mehr lesen

Numerical Simulation of Electrokinetic Convection-Enhanced Delivery of Macromolecules

Y. Ou [1], A. Jaquins-Gerstl [1], S. G. Weber [1],
[1] Department of Chemistry, University of Pittsburgh, Pittsburgh, PA, USA

The brain is a heterogeneous porous medium with regions of anisotropy. Measurements of tortuosity (λ) showed that diffusion in gray matter (e.g. striatum) is isotropic (λ = 1.65), whereas it is anisotropic in white matter (e.g. corpus callosum) (λparallel = 1.38, λperpendicular = 1.80) ...

Comparison of 2D and 3D FEM Models of Eddy Current Pressure Tube to Calandria Tube Gap Measurement

G. Klein [1], J. Morelli [1], T. Krause [2],
[1] Queen's University, Kingston, ON, Canada
[2] Royal Military College of Canada, Kingston, ON, Canada

Two different Finite Element Method (FEM) models of the CANDU® nuclear fuel channels were compared against experimental data to determine if the curvature of the fuel channels is necessary to consider for measurements of the pressure tube to calandria tube gap. The different models were ... Mehr lesen

Simulation of the Effects of Nano-filler Interactions in Polymer Matrix Dielectric Nanocomposites

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

The finite element method was used for simulating the dielectric response of polymer matrix dielectric composites with randomly and evenly distributed fillers. The dielectric simulation of the composite materials was conducted using a time harmonic-electric current solver in the AC/DC ... Mehr lesen

Calculation of Inductance of Sparsely Wound Toroidal Coils

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

Analytical methods used for inductance calculation of toroidal coils yield large errors in the case of coils sparsely wound on low permeability cores. Numerical field calculations can provide “exact” figures. We have outlined several simulation methods. Simplifications, assumptions, and ... Mehr lesen

Numerical Modeling of Magnetic Field Emissions From am HDD Walkover Locating System

A. Jaganathan [1], J. Montoute [1],
[1] Louisiana Tech University, Ruston, LA, USA

In this paper, numerical modeling of the artificially induced magnetic field from a walk-over locator used to detect the drill head underground in Horizontal Directional Drilling (HDD) is presented. Numerical predictions are compared against the experimental data and closed-form ... Mehr lesen
