Low Pt Cathodes for High Performance PEMFCs: Modeling and Experiments

F. Daouda[1], J. Hamelin[1], P. Benard[1], S. Kumar Natarajan [1]
[1]Insitut de recherche sur l'hydrogène, Université du Québec à Trois-Rivières, Trois-Rivières, Québec, Canada

We present a novel multi-layered electrode fabrication technique for polymer electrolyte membrane fuel cells (PEMFCs). This method consists of alternate layers of Pt deposition (0.05 mg/cm²) by sputtering on the painted multi-walled carbon-Nafion layer (CNL) with larger concentration of ... En savoir plus

Transient RF Heating of a Conductive Implant: Coupled Electromagnetic/Thermal Simulation and Experimental Validation

A. Leewood[1], D. Gross[1], J. Crompton[2], S. Yushanov[2], O. Simonetti[3], Y. Ding[3]
[1] MED Institute Inc., West Lafayette, IN, USA
[2] AltaSim Technologies, Columbus, OH, USA
[3] Ohio State University, Columbus, OH, USA

The purpose of this work was to establish a reliable radio frequency (RF) heating simulation which directly provides transient temperatures for medical devices with high geometric fidelity. These temporal results of localized temperatures can be used to determine conditions for safety of ... En savoir plus

Assessment of Anterior Spinal Artery Blood Flow following Spinal Cord Injury

[3]Department of Neurosurgery, Medical University of South Carolina, Charleston, SC, USA
[4]Department of Mechanical Engineering, University of South Carolina, Columbia, SC, USA

The incidence of spinal cord injury (SCI) in the US is approximately 12,000 individuals annually, due to various forms of trauma and disease. Diminished flow over a prolonged period of time can cause permanent spinal damage. We constructed a 3D finite element model of the spinal cord to ... En savoir plus

Going beyond Axisymmetry: 2.5D Vector Electromagnetics

Y.A. Urzhumov[1][,][2], N.I. Landy[1][,][2], C. Ciraci[2], D.R. Smith[1][,][2]
[1]Department of Electrical and Computer Engineering, Pratt School of Engineering, Duke University, Durham, NC, USA
[2]Center for Metamaterials and Integrated Plasmonics, Pratt School of Engineering, Duke University, Durham, NC, USA

Linear wave propagation through inhomogeneous structures of size R?? (Fig.1) is a computationally challenging problem, in particular when using finite element methods, due to the steep increase of the number of degrees of freedom as a function of R/?. Fortunately, when the geometry of ... En savoir plus

Finite Element Solution of Nonlinear Transient Rock Damage with Application in Geomechanics of Oil and Gas Reservoirs

S. Enayatpour[1], T. Patzek[1]
[1]The University of Texas at Austin, Austin, TX, USA

The increasing energy demand calls for advances in technology which translate into more accurate and complex simulations of physical problems. Understanding the rock damage is essential to understanding the geomechanics of hydrocarbon reservoirs. The fragile microstructure of some ... En savoir plus

A COMSOL Model of Damage Evolution Due to High Energy Laser Irradiation of Partially Absorptive Materials

P. Joyce[1], J. Radice[1], A. Tresansky[1], J. Watkins[1]
[1]United States Naval Academy, Annapolis, MD, USA

In this paper we present a transient numerical model of the heat transfer and thermochemical damage evolution in an IR translucent material using COMSOL Multiphysics. The model is evaluated using literature supplied and experimentally determined material properties for carbon black laden ... En savoir plus
