Calculation and Measurement of Winding Loss at High-Frequency Pulsed Currents

A. Pokryvailo1, H. Dave1
1Spellman-High Voltage, Hauppauge, NY, USA

Rich literature exists on calculation of copper loss in windings of high-frequency transformers and inductors. Most of the work was carried out in a Dowell approximation ignoring the windings aspect ratio and core presence. Calculation of losses at non-sinusoidal currents is made usually ... Read More

Solving a Ceramic to Metal Seal Breakdown Problem Using Electric Field Modeling

D. McCormick1
1Baker-Hughes, Twinsburg, OH, USA

In the manufacture of radiation detectors, high voltage bias is often required. Since the detector is housed inside a sealed enclosure a ceramic to metal seal is used to feed this bias voltage to the detector as well as providing connections for the resulting pulse output from the ... Read More

Large-Scale Electrophoretic Fractionation of Rare Earths

C. Ivory1
1Washington State University, Pullman, WA, USA

My research group began applying microchip electrophoresis to fractionation of the rare earths more than a decade ago. The electrophoretic method we applied at microscale was isotachophoresis, which has the ability to quickly concentrate samples by several orders of magnitude while ... Read More

A Preliminary Design of a Hydrodynamic Microtrap for Capturing Aqueous Droplets in Oil Media

E. McDaniel1, S. P. Burugupally1
1Wichita State University, Wichita, KS, USA

Droplet-based microfluidic systems are emerging as an ideal platform for the high-throughput screening of eukaryotic cells aimed to understand the complex, multidimensional, and dynamic biological processes [1]. Here, aqueous droplets – containing the eukaryotic cells – suspended in oil ... Read More

Force and Torque Predictions in a Large-Gap Magnetic Suspension System

C. Britcher1
1Old Dominion University, Norfolk, VA, USA

Magnetic Suspension and Balance Systems (MSBS) are a method of levitating an aerodynamic model in a wind tunnel. An unusual characteristic is that the electromagnet assemblies (outside the wind tunnel) are very large, but the levitated object (a permanent magnet core) is quite small and ... Read More

Reassessing Electrothermal Simulation Techniques to Develop Realistic Models

T. Lijnse1, C. Dalton1, S. Cenaiko1, G. Moscoso1
1University of Calgary, Calgary, Alberta, Canada

Electrokinetic (EK) techniques have been broadly implemented in a variety of fields, including microfluidics and lab-on-a-chip, and are seeing increased interest to miniaturize and optimize fluid pumping and mixing systems. While EK techniques such as electro-osmosis and ... Read More

Ferrofluid Mixing in Double-Layer Microfluidic Device with Microscale Magnet

R. Zhou1, A. N. Surendran1
1Purdue University Northwest, Hammond, IN, USA

Microfluidics-based mixing has been widely used in various areas such as chemical engineering, biomedical engineering and materials science. The micromixer can be strategies into two categories as passive and active method depending on the mixing principle. Magnetic mixing integrated ... Read More

Simulation and Validation of Pollutant Transport in Rivers Using COMSOL Multiphysics®

L. J. Matel1
1Green Streets Infrastructure LLC, Washington, D.C, USA

Our atmosphere, land, and water are being continuously besieged by pollutants caused by such events as heavy metals leaching from mine tailing ponds, chemical spills from railroad and truck tanker accidents, and petroleum pipeline failures, to name just a few. These environmental insults ... Read More

Simulation of Electrothermoplasmonic Flow Around an Array of Gold Nanoantennas for Plasmonic Sensing

E. Ruiz-Reina1, R.A. Rica2, J. García3, R. Quidant4
1University of Málaga, Spain
2University of Granada, Spain
3ICFO-Institut de Ciències Fotòniques, Barcelona In
4ICREA-Institució Catalana de Recerca i Estudis Ava

Plasmonic-based biosensors have emerged as a powerful, cost effective and portable platform for phatogen and biomarker detection. In particular, Localized Surface Plasmon Resonance (LSPR) based systems, which rely on resonance shift tracking, present high sensitivity, specificity and ... Read More

Optimization of Piezoelectric-Triboelectric Hybrid Generator Design

M. Padmanabhan1, G. Barbosa1
1Rhode Island College, Providence, RI, USA

Devices which scavenge energy from ambient mechanical sources such as human body movement and ocean waves are undergoing rapid research and development. Both triboelectric and piezoelectric effects have been employed in the design of such devices. In this work, we use the MEMS Module in ... Read More
