Numerical and Experimental Study of Flow, Heat Transfer and Concentration in a Scaled-up Fuel Cell Anode Channel Model

J. C. Torchia-Nüñez[1], and J.G. Cervantes-de-Gortari[1]

[1]Department of Thermal Engineering, National University of Mexico, UNAM, Mexico City, Mexico

Flow, concentration and temperature fields are studied with numerical and experimental methods inside a scaled-up fuel cell anode channel model. The low aspect ratio channel has a porous medium as the inferior wall where a mixing of different pH solutions occurs. Chromatic change of ... Mehr lesen

Modeling Hydrogen Permeation through a Thin TiO2 Film Deposited on Pd

Z. Qin[1], Y. Zeng[1], and D.W. Shoesmith[1]

[1]The University of Western Ontario, London, Ontario, Canada

Models that describe hydrogen permeation through a thin TiO2 film deposited on Pd have been developed based on a mass-balance equation consisting of diffusion, reversible hydrogen absorption/desorption, and irreversible hydrogen trapping. These models are solved by the finite element ... Mehr lesen

Full-Wave Simulation of an Optofluidic Transmission-Mode Biosensor

E. P. Furlani[1], N. M. Litchinitse[2], and R. Biswas[2]

[1]The Institute for Lasers, Photonics and Biophotonics, University at Buffalo, Buffalo, New York, USA
[2]Department of Electrical Engineering, The State University of New York at Buffalo,Buffalo, New York, USA

We present a study of an optofluidic biosensor. The sensor operates in a transmission mode wherein detection is based on a shift in the transmission spectrum caused by the contrast in refractive index between the carrier fluid and the target biomaterial. We study the behavior of the ... Mehr lesen

An Efficient Finite Element Analysis on an RF Structure Used to Evaluate the Effect of Microwave Radiation on Uveal Melanoma Cells

A. Dulipovici[1], D. Roman[2], I. Stiharu[2], and V. Nerguizian[1]

[1]École de technologie supérieure, Montreal, Quebec, Canada
[2]Concordia University, Montreal, Quebec, Canada

The use of Microwave/RF energy on cancer cells is explored for tumor ablation using medium power level ranging between a few Watts to about 50 Watts. In this research, low power levels, less than 100 mWatt, are used to evaluate the effect of this energy on Uveal melanoma cells by ... Mehr lesen

Bending of a Stented Atherosclerotic Artery

H.C. Wong[1], K.N. Cho[1], and W.C. Tang[1]

[1]Department of Biomedical Engineering, University of California, Irvine, California, USA

Atherosclerosis causes the deposition of plaque on the inner walls of arteries, which leads to restricted blood flow. Using the balloon angioplasty procedure, stents can be inserted and expanded in the atherosclerotic artery. We used COMSOL Multiphysics Structural Mechanics, Solid Stress ... Mehr lesen

Image-based Simulation of Electrical Impedance Techniques Applied on the Human Thorax for Cardio-pulmonary Applications

A. Harkara[1], R.M. Heethaar[2], R.T. Cotton[1], and F.K. Hermans[2]

[1]Simpleware Ltd., Exeter, UK
[2]VU University Medical Center, Amsterdam, Netherlands

For medical diagnostic purposes there is an increasing need for non-(or minimal) invasive techniques to measure all kinds of parameters that can provide insight in the functioning of cells, organs or organ systems. Currently, Impedance Cardiography (ICG) is used for measurements of the ... Mehr lesen

Nanoscale Heat Transfer using Phonon Boltzmann Transport Equation

S. Sihn[1,2], and A.K. Roy[2]

[1]Air Force Research Laboratory, Wright-Patterson Air Force Base, Dayton, Ohio, USA
[2]University of Dayton Research Institute, Dayton, Ohio, USA

COMSOL Multiphysics was used to solve a phonon Boltzmann transport equation (BTE) for nanoscale heat transport problems. One dimensional steady-state and transient BTE problems were successfully solved based on finite element and discrete ordinate methods for spatial and angular ... Mehr lesen

Drying of Corn Kernels: From Experimental Images to Multiscale Multiphysics Modeling

P. Takhar[1], and S. Zhang[2]

[1]Texas Tech University, Lubbock, Texas, USA
[2]Visualization Sciences Group Inc., Burlington Massachusetts, USA

This work demonstrated the importance and feasibility of experimental image to simulation workflow. The workflow is successfully applied to a food processing study, where multiphysics and multiscale modeling based on 3D experimental image reconstruction contributes to the preservation of ...
