Plasmonic Waveguide Analysis

K. C. Koppenhoefer [1], S. Yushanov [1], J. S. Crompton [1],
[1] AltaSim Technologies, Columbus, OH, USA

Surface Plasmons (SP) or Surface Plasmon Polaritons (SPP) are electromagnetic excitations that propagate at the interface between a dielectric and a conductor, and are evanescently confined in the perpendicular direction to the propagation. They arise via coupling of the electromagnetic ... En savoir plus

Multiphysics Analysis of an Infrared Bolometer

J. S. Crompton [1], J. Thomas [1], K. Koppenhoefer [1],
[1] AltaSim Technologies, Columbus, OH, USA

Bolometers are used in a number of applications including night vision cameras, astronomy, and particle physics to measure the power of incident electromagnetic radiation. The general principle of operation is shown below: a strip of conducting material is exposed to incident ... En savoir plus

Modeling of a Multilayered Propellant Extrusion in Concentric Cylinders

S. Durand [1][3], C. Dubois [1], P. Lafleur [1], V. Panchal [2], D. Park [2], P. Paradis [3], D. Lepage [3]
[1] École Polytechnique de Montréal, Montréal, QC, Canada
[2] US Army ARDEC, Picatinny Arsenal, NJ, USA
[3] General Dynamics OTS Canada Valleyfield, Salaberry-de-Valleyfield, QC, Canada

A novel propellant technology requires extruding two formulations with differential burning rates (slow and fast) together as a multilayered propellant. This multilayered propellant is processed into a concentric cylinder configuration, in the form of slow-fast-slow with single ... En savoir plus

Analysis of a Plasma-Mediated Photoacoustic Response From Plasmonic Nanoparticles in Ultrashort Regime

A. Hatef [1], B. Darvish [1], A. Dagallier [2], C. Boutopoulos [2], M. Meunier [2],
[1] Nipissing University, North Bay, ON, Canada
[2] École Polytechnique de Montréal, Montréal, QC, Canada

Over the last decade, plasmonic nanoparticles (PNPs) have received growing interest as exogenous contrast agents in the thermal expansion based photoacoustic (PA) imaging technique in biomedical applications [1]. Such functionality is due to the localized surface plasmon resonance (LSPR) ... En savoir plus

Multiphysics Simulation of a Printed Circuit Heat Exchanger

A. Daouk [1], O. E. Petel [1], H. Saari [1],
[1] Carleton University, Ottawa, ON, Canada

Compact Heat Exchangers, specifically Printed Circuit Heat Exchangers, are widely used in industry as a replacement for traditionally large heat exchangers (e.g. Shell and Tube) due to their small size and high effectiveness. Modelling of PCHEs, specifically those manufactured by Heatric ... En savoir plus

Numerical Modeling of 3D Electrowetting Droplet Actuation and Cooling of a Hotspot

M. M. Nahar [1], H. Moon [1], G. S. Bindiganavane [1], J. Nikapitiya [1]
[1] Department of Mechanical and Aerospace Engineering, University of Texas - Arlington, Arlington, TX, USA

Electrowetting on Dielectric (EWOD) is a versatile tool for performing basic operations in Digital Microfluidic Systems. In EWOD, surface tension between a liquid droplet and solid substrate is modulated by applying voltage to an electrode and a hydrophobic surface is transformed into a ... En savoir plus

Modeling a Lung-on-a-Chip Microdevice

M. J. Hancock [1], N. Elabbasi [1],
[1] Veryst Engineering, LLC., Needham, MA, USA

Organ-on-a-chip microdevices combine microfluidics, MEMS, and biotechnology techniques to mimic the multicellular architectures, tissue-tissue interfaces, physicochemical microenvironments, and vascular perfusion of the body.[1] Such devices are being developed to provide better levels ...

Multiphysics Model for Breakup of Charged Liquid Droplets in Electric Fields

S. Chaudhuri [1], W. Du [1],
[1] University of Illinois at Urbana-Champaign, Champaign, IL, USA

Predicting and controlling the formation of droplets from a liquid jet is a critical problem in a variety of applications ranging from fuel injection to paint sprays. It is known that liquid droplets subjected to an electric field acquire a net electrostatic charge via induction, and ... En savoir plus

COMSOL Multiphysics® Software Simulation of a Dual-axis MEMS Accelerometer with T-Shaped Beams

C. Zheng [1], X. Xiong [1], J. Hu [2]
[1] Department of Electrical and Computer Engineering, University of Bridgeport, Bridgeport, CT, USA
[2] Department of Mechanical Engineering, University of Bridgeport, Bridgeport, CT, USA

Introduction: Inertial navigation requires acceleration measurement along all three degree-of-freedoms. Most accelerometers are designed to measure acceleration along a single sensitive direction. For complete inertial sensing, a move effective accelerometer which can sense ... En savoir plus

Simulation of the Geometric Design Parameters’ Impact on the Performance of EHD Ion-Drag Micropump

M. Badran [1],
[1] Future University in Egypt, New Cairo, Egypt

A two-dimensional numerical simulation study has been performed to model an electrohydrodynamic (EHD) micropump. The emphasis of this study was on simulating the effect of the different geometric design parameters on the micropump pressure head and volume flow rate. The simulated design ... En savoir plus
