2D Flow Past a Confined Circular Cylinder with Sinusoidal Ridges

R. Wulandana[1], K. Cavanagh[1]
[1]State University of New York (SUNY) at New Paltz, USA

Flow past a circular cylinder arises in many engineering applications, but there is significantly less work studying flow past a cylinder in a confined domain, such as pipe flow or flow in a plane channel. There are many applications where the scaling of a particular problem requires ... En savoir plus

Actuation Force Study of Next Generation Micro Shutter Array for More Reliable Actuation

K. Kim[1], M. Li[2], A. Kutyrev[3], M. Greenhouse[2]
[1]NASA Goddard Space Flight Center/Science Systems and Applications Inc., USA
[2]NASA Goddard Space Flight Center, USA
[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 ... En savoir plus

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 ... En savoir plus

MOSFET Channel Engineering and Scaling Study using COMSOL Multiphysics® Simulation Software

D. Subedi[1], D. Fixel[1]
[1]Trinity College, USA

With the scaling of semiconductor devices into the nanometer regime, short channel effects are an ever-present issue. Among these effects are threshold voltage variation with channel length, reduced output resistance, punch-through and hot-electron degradation. The effect of constant ... En savoir plus

Plastic Deformation of Metallic Foam

M. Cops[1], J. McDaniel[1], E. Magliula[2], D. Bamford[2]
[1]Boston University, USA
[2]Naval Undersea Warfare Center Division Newport, USA

Metallic foams can be plastically deformed to dramatically alter the material’s mass density, microstructure, and bulk mechanical properties. This work investigates the plastic deformation of open-cell aluminum foams numerically, using high fidelity models of metallic foam constructed ... En savoir plus

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 ... En savoir plus

Numerical Evaluation on Cutoff Frequency of Twisted Waveguide with Rectangular Cross-section

J. Wang[1]
[1]Keisoku Engineering System Co., Ltd., Japan

Waveguides are widely adopted for propagation of high frequency signals. Due to misalignment of waveguide system, bended or twisted waveguide is demanded for connection between waveguides. Compared with straight waveguides, twisted waveguides have a shift of cutoff frequency ... En savoir plus

Optimal Design of Bass Reflex Loudspeaker Ports

A. Bezzola[1]
[1]Samsung Research America, USA

Determining an optimal port profile for a vented loudspeaker is still an unsolved problem. Studies that measured distortion content suggest a gently flared port is best, while subjective listening tests suggest that more aggressive flare rates are optimal at low to moderate levels, but ...
