Modeling the Electric Double Layer in Finite Electrolyte Solutions

J. C. Woehl [1],
[1] University of Wisconsin - Milwaukee, Milwaukee, WI, USA

While electric double layers play a crucial role in many biophysical processes involving charged molecular species (such as proteins and DNA), they are often a limiting factor in technological applications where charged conductors are brought in contact with electrolyte solutions. ...

Magnetic Control of Deformation of a Ferrofluid Droplet in Simple Shear Flow

C. Wang [1], M. R. Hassan [1],
[1] Department of Mechanical and Aerospace Engineering, Missouri University of Science and Technology, Rolla, MO, USA

This study investigates the effect of uniform magnetic field on the deformation of a ferrofluid droplet in a two dimensional (2D) simple shear flow by means of numerical simulation. The magnetic field is applied in a perpendicular direction to the flow direction. A numerical scheme ... En savoir plus

Load Noise Calculation of a Three-Phase Power Transformer

C. S. Lin [1],
[1] Pitotech. Co Ltd., Changhua City, Changhua, Taiwan

Vibrations and noise of high power transformers have attracted considerable experimental and theoretical interests over last few years [1, 2]. For such transformers operating under high voltage (~ 100 kV) and power (~ 100 MVA), noise generated is significantly attributed to load noise ... En savoir plus

Electrical Energy Harvesting from Body Heat: Indirect Conversion via Mechanical Vibration

S. Shin [1], H. Mojtaba [1], F. Ayazi [1],
[1] Georgia Institute of Technology, Atlanta, GA, USA

Recent rapid progress in MEMS with wireless communication system has enabled low power micro sensor network for human body, Body Area Sensor Network (BASN). The information gathering from BASNs will provide a significant opportunities for various medical applications. One of the key ... En savoir plus

COMSOL® Analysis-Led Design of Prototype Coil Program for Bi-2212 Coils

E. Bosque [1], U. Trociewitz [1],
[1] Applied Superconductivity Center - National High Magnetic Field Laboratory, Tallahassee, FL, USA

The National High Magnetic Field Laboratory (NHMFL) strives to push magnet technology to ever higher field strengths. Supported by a unified effort of material research as well as coil research, Bi2Sr2CaCu2O8+δ (Bi 2212) technology shows promise as a high temperature superconductor (HTS) ... En savoir plus

Anodic Dissolution Model Parameterization for Pulsed Electrochemical Machining Coupled with a Magnetic Field

C. Bradley [1],
[1] Benét Laboratories, U.S. Army RDECOM-ARDEC, Watervliet, NY, USA

Manufacture of complex micro-scale parts such as biomedical devices and micro tools that require an excellent surface finish has required non-conventional manufacturing processes such as pulsed electrochemical machining (PECM). Additional reverse polarity pulses make the PECM bipolar ... En savoir plus

3D Modeling of Transformation Optics based Flattened Luneburg Lens Using the COMSOL Multiphysics® Software

S. Biswas [1], M. S. Mirotznik [1],
[1] University of Delaware, Newark, DE, USA

Three-dimensionally varying flattened Luneburg Lens structure whose axisymmetric invariance of material parameters is calculated by conformal mapping, presents a numerical challenge for three dimensional modelling. To address this problem, conventionally a two dimensional quasi-conformal ... En savoir plus

Using the COMSOL Multiphysics® software for simulation of TEGs for Waste Thermal Energy Harvesting

L. Howard [1], D. Tafone [2], D. Grbovic [1], A. Pollman [1],
[1] Naval Postgraduate School, Monterey, CA, USA
[2] Ramapo College of New Jersey, Mahwah, NJ, USA

Navy systems, such as turbine engines, produce large quantities of thermal energy. This energy is a byproduct of the work produced by the engine during operation and is typically rejected to its surroundings. The temperature difference between the turbines and the ocean is substantial ... En savoir plus

Using Multiphysics to Quantify Leakage Rates in New and Rehabilitated Sewer and Water Pipes

C. Hansen [1],
[1] Electro Scan Inc., Sacramento, CA, USA

Traditionally, municipal sewer and water agencies have relied on acoustic data loggers and closed-circuit television cameras to inspect pipes for leaks. In addition, the same legacy techniques have been used to certify new and rehabilitated pipes as watertight. Unfortunately, visually ... En savoir plus

Numerical Evaluation of the Polarizability Tensors of Stem Cells with Realistic 3D Shapes

S. Baidya [1], A. M. Hassan [1], B. A. Pazmiño Betancourt [2], J. F. Douglas [2], E. J. Garboczi [3],
[1] Computer Science Electrical Engineering Department, University of Missouri - Kansas City, Kansas City, MO, USA
[2] Materials Science and Engineering Division, National Institute of Standards and Technology, Gaithersburg, MD, USA
[3] Applied Chemicals and Materials Division, National Institute of Standards and Technology, Gaithersburg, MD, USA

Most of the reported studies on the electrical characteristics of biological cells assume that they have simple shapes like spheres or ellipsoids due to the lack of information about their accurate 3D shape. However, the actual shape of a cell can be quite fractal and it must be taken ... En savoir plus
