COMSOL® Analysis for Duct Acoustic

M. M. Ghulam [1], E. J. Gutmark [1],
[1] Aerospace Department, University of Cincinnati, Cincinnati, OH, USA

COMSOL analysis of the acoustic modes of two different Combustion Wind Tunnel Facility’s test sections was conducted in this project. The test sections are rectangular ducts, therefore the mathematical expressions to predict the longitudinal and transverse modes inside a tube were used ... Read More

Numerical Model Simulation of Impedance Based Control for RF Ablation Using Isolator Synergy Clamp

M. Etheridge [1], R. Lopusnik [1], A. Cates [1],
[1] AtriCure, Inc., Minnetonka, MN, USA

Thermal ablation is rapidly becoming a standard of care for the treatment of atrial fibrillation (AF), a cardiac disorder characterized by irregular heart rhythm and estimated to impact more than 33 million people worldwide (Chugh et al. Circulation (2013)). AtriCure is a company that ... Read More

Nanofluidic Analyte Preconcentration Using Fluid Field-Effect Diodes

A. Eden [1], K. Scida [1], J. C. T. Eijkel [2], C. D. Meinhart [1], S. Pennathur [1],
[1] University of California, Santa Barbara, CA, USA
[2] University of Twente, Enschede, Netherlands

Introduction Throughout the field of micro- and nanoscale electrokinetics, floating bipolar electrodes (BPEs) have proven to be useful in manipulating charged ionic species and biomolecules for electroanalytical studies. The growing use of integrated electronics in working towards fully ... Read More

Numerical Simulation of Pool Film Boiling Heat Transfer during Quenching of Heated Cylindrical Rods

S. Ebrahim [1], F. B. Cheung [1], A. Alshayji [2],
[1] Department of Mechanical and Nuclear Engineering, Pennsylvania State University, University Park, PA, USA
[2] Department of Mechanical Engineering, College of Engineering and Petroleum, Kuwait University, Kuwait

This research studies possible ways to mitigate failure of a nuclear reactor, in which the coolant supply to the nuclear core has been compromised, known as Loss of Coolant Accident (LOCA). One possible way to decrease the severity of the incident is to quickly quench the fuel rods in ... Read More

Thermal Model and Control of Metal-Organic Chemical Vapor Deposition Process

J. L. Ebert [1], S. Ghosal [1], N. Acharya [1]
[1] SC Solutions, Inc., Sunnyvale, CA, USA

Metal-Organic Chemical Vapor Deposition (MOCVD) is used for the manufacture of Multi-Quantum Well Light Emitting Diodes (MQW LEDs). The process uses a carrier gas flow containing a dilute mixture of metal organic precursors, Tri-Methyl Gallium (TMG) and Tri-Methyl Indium (TMI), to ... Read More

Silicon-Organic-Hybrid Independent Simultaneous Dual-Polarization Modulator: Device Theory and Design

Y. D'Mello [1], M. Hui [1], J. Skoric [1], M. Haines [1], A. Kirk [1], M. Andrews [1], D. Plant [1],
[1] McGill University, Montréal, QC, Canada

The Complementary Metal-Oxide-Semiconductor (CMOS) technology is a gateway to fabricating low cost electronic and photonic components to date. The Silicon-based nanophotonics platform leverages CMOS technology to fuel the effort to provide increasingly high-speed and high-bandwidth ... Read More

Numerical Analysis and Optimization of a Multi-Mode Interference Based Polarization Beam Splitter

Y. D'Mello [1], E. Elfiky [1], J. Skoric [1], D. Patel [1], D. Plant [1]
[1] McGill University, Montréal, QC, Canada

The progression toward smaller and faster photonic circuits has led to the development of nanophotonic platforms capable of compacting many devices onto an integrated chip. These devices, as well as the input and output grating couplers, are sometimes polarization dependent, which allows ... Read More

A Multiphysics Model of O2 Transport and Recirculation During Venovenous Extracorporeal Life Support

S. Conrad [1],
[1] Louisiana State University Health Sciences Center, Shreveport, LA, USA

Venovenous extracorporeal life support (VV-ECLS) provides gas exchange support for severe lung failure by using an extracorporeal circuit consisting of a blood pump and an artificial membrane lung. Blood is withdrawn from a cannula placed into the inferior vena cava, and returned from ... Read More

An Evaluation of CO2 Sequestration in Organic-Rich Shales Using COMSOL Multiphysics®

R. Barati [1], S. Cudjoe [1],
[1] University of Kansas, Lawrence, KS, USA

Organic-rich shale resources remain an important source of hydrocarbons considering their substantial contribution to crude oil and natural gas production around the world. Moreover, as part of mitigating the greenhouse gas effects due to the emissions of carbon dioxide (CO2) gas, ... Read More

Loudspeaker Response Optimization with the Aid of Impulse Response

R. Balistreri [1],
[1] Klipsch Group, Inc., Indianapolis, IN, USA

COMSOL Multiphysics® simulation software is receiving a lot of attention in the loudspeaker industry thanks to the quality of the results it provides making it an essential tool to optimize geometries so that the best reproduction capabilities of the loudspeaker system are achieved. ... Read More
