Upward Lightning Exposure Assessment for Wind Power Plants in Low Altitude Thunderstorms using COMSOL Multiphysics®

S. Vogel[1], A. Candela Garolera[1], J. Lopez[1], S. Madsen[1]
[1]PolyTech A/S, Denmark

Cold season thunderstorms are a threat for wind turbines in several areas of the world because the thundercloud is much closer to the earth compared to warm season thunderstorms. As a consequence, the electric field between cloud and ground is much higher during these storms, triggering ... En savoir plus

Magnetic Manipulation of Lateral Migration Behavior of a Ferrofluid Droplet in a Plane Poiseuille Flow

M. Hassan[1], C. Wang[1]
[1]Missouri University of Science and Technology, USA

This study investigates the effect of a uniform magnetic field on the lateral migration behavior of a ferrofluid droplet in a plane Poiseuille flow at arbitrary directions by means of numerical simulation. A numerical scheme called level set method in combination with the laminar two ... En savoir plus

Chaining Dynamics of a Pair of Ellipsoidal Micro-Particles Under a Uniform Magnetic Field

J. Zhang[1], C. Wang[1]
[1]Missouri Univ of Sci and Tech, USA

Due to particle interactions, magnetic particles suspended in non-magnetic fields tend to form chains, clusters or columns under magnetic fields. The non-spherical magnetic particles in the suspension show different rheological properties compared to spherical particles. In this paper, ... En savoir plus

Improved Charge Amplification in Microfluidic Energy Harvesting Using COMSOL Multiphysics® Simulation Software

S. Mackenzie[1], A. Eden[1], M. Prichard[1], B. Dutcher[1], C. Meinhart[1], D. Huber[1], M. Napoli[1], D. Weld[1], S. Pennathur[1]
[1]University of California, Santa Barbara, USA

We present a detailed 2D COMSOL Multiphysics® model used to determine and improve the conversion efficiency in a liquid-metal microfluidics-based portable energy transducer. To date, most work on power generation technologies has focused on the optimization of existing technologies, and ... En savoir plus

Visualization and Exploration of the Dynamics of Phase Slip Centers in Superconducting Wires

I. Dorn[1], A. Gulian[1]
[1]Chapman University, USA

The dynamics of phase slip centers in a 1D model of superconducting wire was created based on the set of time-dependent Ginzburg-Landau equations (TDGL). The General Form PDE interface of COMSOL Multiphysics® simulation software was used. TDGL has successfully applied to this problem ... En savoir plus

The Proximity Effect: A Comparison of COMSOL Multiphysics® and Analytic Solutions

C. Cooke[1], L. Shatz[2]
[1]Massachusetts Institute of Technology, USA
[2]Suffolk University, USA

An important attribute for numerical simulations is to provide accurate quantified solution values. Thus it is useful to find complex problems with analytic solutions to confirm the numerical results obtained from software. The well-known proximity effect causes a redistribution of ...

COMSOL Multiphysics® Based Inductance Estimation for Modeling Transformer Winding Faults in EMTP

H. Vemprala[1], B. Mork[1]
[1]Michigan Technological University, USA

Power Transformers are the most important piece of power system elements and protecting this device from failures, especially from the internal faults has been a major challenge. The internal faults such as Turn-to-Turn (T2T) and Turn-to-Ground (T2G) has been attributed to most of the ... En savoir plus

Finite Element Modeling of Beam Deflection in Photothermal Deflection Spectroscopy

M. Kline[1], P. Nichols[1], J. Pedroza Ramirez[1], S. Johnson[1]
[1]Transylvania University, USA

Photothermal deflection spectroscopy (PDS) relies on the angular displacement of a probe beam through a fluid with varying index of refraction. The precise angular displacement of the probe beam is dependent on the entire index of refraction field, which is in turn dependent on fluid ... En savoir plus

Low-Cost and Portable Microwave Medical Imaging for Stroke Detection

W. Mai[1], Y. Ding[2], M. Chi[2], Y. Zhou[3], H. Wang[4], X. Lin[4], Z. Gong[4], F. Xia[5], Y. Chen[2]
[1]Pennsylvania State University, China
[2]University of Electronic Science and Technology of China, China
[3]Beijing Institute of Collaborative Innovation, China
[4]The University of Waikato, New Zealand
[5]Southen University of Science and Technology, China

CT and MRI are current techniques used for stroke detection. Although they are favored for their high accuracy and resolution, there are many situations that a potable and low-cost imaging technique is required. Ultra-sound technique is portable, but it cannot be used for stroke ... En savoir plus

COMSOL Multiphysics® Simulation of Electrical Bioimpedance Impedance in a Simplistic Model of Human Thorax

P. Rajan[1]
[1]Analog Devices, USA

The quantitative value of electrical bio impedance in tissue structures is sensitive to changes in ionic concentration, frequency and dispersion but lacks specificity. It is difficult to a create a physical measurement set up of clinical value capable of quantifying the contribution of ... En savoir plus
