The Effects of the Electrical Double Layer on Giant Ionic Currents through Single Walled Carbon Nanotubes

G. Zhang[1][,][2][,][3], S.L. Bearden [1]
[1]Department of Bioengineering, Clemson University, Clemson, SC, USA
[2]Department of Electrical and Computer Engineering, Clemson University, Clemson, SC, USA
[3]Institute for Biological Interfaces of Engineering, Clemson University, Clemson, SC, USA

Electrofluidic transport through a single walled carbon nanotube (SWCNT) is enhanced by electroosmosis. Electroosmosis is made possible in these devices by the combination of a large slip length within SWCNTs and the interfacial potential at the solution/nanotube interface. A ... Read More

Orientation of Piezoelectric Crystals and Acoustic Wave Propagation

G. Zhang[1]
[1]Clemson University, Clemson, SC, USA

Surface acoustic wave (SAW) devices are commonly used as wireless filters, resonators, and sensors. The confinement of acoustic energy near the surface of a piezoelectric substrate in a SAW sensor makes it highly sensitive for discerning surface perturbation. As sensors, SAW devices have ...

Modeling the Squeeze Flow of a Thermoplastic Composite Tape during Forming

A. Levy[1], G.P. Picher Martel[1], P. Hubert[1]
[1]McGill University, Montreal, QC, Canada

Thermoplastic composite such as APC2 (Carbon/PEEK) are usually shipped as semi-finite tape products. Final product is obtained with forming by applying heat and pressure. A key phenomena is the squeezing of the tape. In this paper we compare the solution of the squeeze flow using a ... Read More

Simulation of Acoustic Energy Harvesting Using Piezoelectric Plates in a Quarter-Wavelength Straight-Tube Resonator

B. Li[1], J.H. You[1]
[1]Southern Methodist University, Dallas, TX, USA

An acoustic energy harvesting mechanism at low frequency (~200 Hz) using lead zirconate titanate (PZT) piezoelectric cantilever plates placed inside a quarter-wavelength straight-tube resonator has been studied using COMSOL Multiphysics 4.3 and compared with experimental data. When the ... Read More

Multiphase Transport with Large Deformations Undergoing Rubbery-Glassy Phase Transition: Applications to Drying

T. Gulati[1], A. Datta[1]
[1]Department of Biological and Environmental Engineering, Cornell University, Ithaca, NY, USA

Drying of biomaterials such as foodstuffs involves mass, momentum and energy transport along with large shrinkage of the porous material, which have significant effects on their final quality. Foodstuffs exhibit non-linearity when undergoing large deformations that affect the transport ... Read More

Application of COMSOL Multiphysics in the Simulation of Magnesium Refining and Production

X. Guan[1], E. Gratz[1], U. Pal[1]
[1]Division of Materials Science and Engineering, Boston University, Brookline, MA, USA

Computational fluid dynamics (CFD) modeling is a useful tool to gain an insight into various high temperature metallurgical processes such as the magnesium refining and the magnesium solid oxide membrane (SOM) electrolysis. In both processes, argon gas was used to stir the molten salt ... Read More

Numerical Study of a DC Electromagnetic Liquid Metal Pump: Limits of the Model

N. Kandev[1]
[1]Institut de recherche d'Hydro-Québec, Shawinigan, QC, Canada

This work presents the results of a 3D numerical magneto-hydrodynamic (MHD) simulation of an electromagnetic DC pump for liquid metal using a rectangular metal flow channel subjected to an externally imposed transversal inhomogeneous magnetic field. In this study. 3D numerical simulation ... Read More

Penetration of Moisture in a Solar Panel Edge Seal

P.K. Mercure[1]
[1]The Dow Chemical Company, Midland, MI, USA

Photovoltaic systems can degrade with moisture. The addition of an edge-seal containing a desiccant can reduce the amount of water reaching the interior. This report discusses the modeling of the water transport into the system to determine the amount of edge seal and desiccant ... Read More

Thermal Adversity in Solid-State Lighting

T. Dreeben[1]
[1]OSRAM SYLVANIA, Beverly, MA, USA

COMSOL Multiphysics is used to simulate natural convection and its impact on peak operating temperatures of solid-sate lighting in thermally adverse conditions. PDE modes in the general form are used in conjunction with a thin-surface conduction formulation in the weak form. COMSOL is ... Read More

Vibration and Acoustic Analysis of a Trussed Railroad Bridge under Moving Loads

R. Costley[1], H. Diaz-Alvarez[1], M. McKenna[1], A. Miller[1]
[1]U.S. Army Engineer Research and Development Center, Vicksburg, MS, USA

Two finite element models have been developed to investigate the acoustic radiation from a Pratt truss train bridge. The first model was a time dependent structural model that determined the vibration response of the structure due to two wheels, representing a single axle, moving across ... Read More
