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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

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 ... 詳細を見る

Solid-Liquid Phase Change Simulation Applied to a Cylindrical Latent Heat Energy Storage System

D. Groulx[1], and W. Ogoh[1]

[1]Mechanical Engineering Department, Dalhousie University, Halifax, Nova Scotia, Canada

One way of storing thermal energy is through the use of latent heat energy storage systems. One such system, composed of a cylindrical container filled with paraffin wax, through which a copper pipe carrying hot water is inserted, is presented in this paper. It is shown that the physical ... 詳細を見る

Wall Effects in Convective Heat Transfer from a Sphere to Power Law Fluids in Tubes

D. Song[1], R. Gupta[1], and Chhabra[2]

[1]West Virginia University, Morgantown, West Virginia, USA
[2]Indian Institute of Technology, Kanpur, India

Heat transfer from a sphere having a uniform temperature and falling axially in a cylindrical tube filled with an incompressible power-law liquid is numerically investigated. The governing equations for simultaneous flow around a confined sphere and heat transfer to power-law fluids were ... 詳細を見る

Multiphysics Simulation of a Packed Bed Reactor

A.E. Varela[1], and J.C. García[1]

[1]University of Carabobo, Valencia, Venezuela

Most reactor designs are based on pseudo homogeneous models. This paper studies the COMSOL simulation of a packed bed reactor using a 2-D heterogeneous model. The case considered was a packed reactor with spherical catalyst for oxidation of o-xylene in air to phthalic anhydride. Large ... 詳細を見る

COMSOL in a New Tensorial Formulation of Non-Isothermal Poroelasticity

A. Mario-Cesar Suarez[1], and V. Fernando Samaniego[2]

[1]Faculty of Sciences, Michoacan University, Morelia, Mich., Mexico
[2]Faculty of Engineering, National University of Mexico, Mexico City, Mexico

The presence of a moving fluid in a porous rock modifies its mechanical response. Poroelasticity explains how the fluid inside the pores bears a portion of the total load supported by the rock. The remaining part of the load is supported by the elastic skeleton, which contains a laminar ... 詳細を見る
