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 ... Mehr lesen

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

[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 ... Mehr lesen

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 ... Mehr lesen

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 ... Mehr lesen

High Current and Multiphysics Modeling of Carbon Fiber Reinforced Polymers (CFRP) Plates and Joints Under Lightning Strike Conditions

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

This paper presents multiphysics modeling of coupled thermal-electrical behavior across the composite joints formed by highly anisotropic conductivity materials such as carbon fiber reinforced polymers (CFRP) under lightning strike conditions and demonstrates the driving physics behind ...

Working Towards Magnetic Barkhausen Noise Detection on Curved Surfaces

L. Burchell[1], P. Underhill[2], T. Krause[2]
[1]Queen's University, Canada
[2]Royal Military College of Canada, Canada

Magnetic Barkhausen noise (MBN) is an emerging field in non-destructive testing, which utilizes the electromagnetic signals generated by small abrupt changes in magnetic field in a sample undergoing magnetization by an applied external magnetic field. These small ... Mehr lesen

An Inverted Process for the Streamlined Design of Electromagnetic Coils

M. Kline[1], A. Saftah[2], M. McCrea[2], C. Crawford[2]
[1]Transylvania University, USA
[2]University of Kentucky, USA

High precision ‘designer’ magnetic fields are needed for the latest generation of particle physics experiments, such as the search for the Electric Dipole Moment of the neutron. The shift in focus from the high energy frontier to precision measurements of these small quantities will ... Mehr lesen

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]
