[3]NASA Goddard Space Flight Center/University of Maryland College Park, USA

Micro shutter array (MSA) is a programmable optical spatial filtering device fabricated by micro electro-mechanical system (MEMS) technology. It was originally developed for James Webb Space Telescope (JWST) to enable multi-object spectroscopy and operated by a moving magnet. Next ... Mehr lesen

Simulation of Organic Thin Film Transistors for Gas Sensing Application

W. Wondmagegn[1], H. Katz[2], J. Huang[3], Y. Chu[2], H. Li[2]
[1]Frostburg State University, USA
[2]Johns Hopkins University, USA
[3]Tongji University, China

Organic Thin Film Transistors are simulated for gas sensing application. The simulation is performed using COMSOL Multiphysics® simulation software's Semiconductor Module. Drift-diffusion (DD) simulation model is used in which the basic equations used are similar to those used for a ... Mehr lesen

Model Time Step Consideration for Modeling Electron Drift in Argon and Helium

D. McCormick[1]
[1]BHGE, USA

For many decades Helium-3 (3He) and Argon gas filled detectors have been used for neutron and gamma detection. Detection requires the generation of electrons which can then be measured by electronic means. These electrons are generated either directly through gamma ionization of a gas ... Mehr lesen

HVDC Electrode Impact Assessment using the AC/DC Module of COMSOL Multiphysics® Simulation Software

L. Carloni[1], S. Madsen[2], H. Rosenberg[3]
[1]PolyTech Lightning A/S, Denmark
[2]PolyTech A/S, Denmark
[3]Balslev Consulting Engineers A/S, Denmark

HVDC electrodes are installed on HVDC transmission systems to provide a low resistance current return path during both monopolar and bipolar operation, using the earth and/or sea as the conductive medium. HVDC electrodes are in general less costly and have lower losses than dedicated ... Mehr lesen

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 ... Mehr lesen

Behind the Magic: Building Better Magnetic Fields

A. Reid[1]
[1]Indiana University, USA

Disciplines such as neutron polarimetry and medical imaging depend on highly uniform magnetic fields to preserve target polarization, and have turned to "magic boxes" to reliably generate these fields. Searches for the permanent Electric Dipole Moment of the neutron (nEDM) are sensitive ... Mehr lesen

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, ... Mehr lesen

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 ... Mehr lesen

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
