Reynolds Number Dependent Porous Media Flow Using the Brinkman Equation

R. Rieck[1], A. Bénard[1], and C. Petty[1]
[1]Michigan State University, Michigan, USA

Porous media fluid dynamic modeling has been widely explored and utilized in many academic and industrial applications. Cross flow filtration being one attractive application, whereas the fluid and filtrate flow parallel the porous media, and thereby induce shearing stress along the ... Read More

Simulation of Electromagnetic Enhancement in Transition Metamaterials using COMSOL

I. Mozjerin[1], T. Gibson[1], and N.M. Litchinitser[1]
[1]Department of Electrical Engineering, The State University of New York at Buffalo, Buffalo, New York, USA

Metamaterials are a new class of artificial materials, which possess various unusual properties. One of these properties is a negative index of refraction produced by setting both the dielectric permittivity ε and the magnetic permeability μ of the material less than zero. Unique ... Read More

Stochastic Modeling of Biological Systems – Ranking the Model Parameters of the Human Vocal Folds

D. Cook[1]
[1]New York University, New York, USA

Computational models of biological systems are becoming more and more common in medical research areas. Evidence of this can be found by examining the number of articles containing the term “finite element” in the expansive National Institutes of Health (NIH) digital research archive ... Read More

Stress Field Simulation for Quantitative Ultrasound Elasticity Imaging

L. Yuan[1] and P.C. Pedersen[1]
[1]Department of Electrical and Computer Engineering, Worcester Polytechnic Institute, Worcester, Massachusetts, USA

Finite element models using COMSOL Multiphysics and MATLAB were developed to solve the problem of stress distribution interior homogeneous, isotropic, incompressible elastic solid material under known vertical external compression with a rectangular contact surface. Moreover, comparison ... Read More

Study of Fluid and Mass Adsorption Model in the QCM-D Sensor for Characterization of Biomolecular Interaction

H.J. Kwon[1], C.K. Bradfield[1], B.T. Dodge[1], and G.S. Agoki[1]
[1]Department of Engineering and Computer Science, Andrews University, Berrien Springs, Michigan, USA

Increasing attention has been paid to application of the quartz crystal microbalance with dissipation (QCM-D) sensor for monitoring biomolecular interactions. This paper focuses on a practical application of protein-protein binding affinity measurement at low concentrations and minimal ... Read More

The Effect of a Correlated Surface Roughness and Convection on Heat Conduction

A.F. Emery[1]
[1]Department of Mechanical Engineering, University of Washington, Seattle, Washington, USA

Heat conduction through a slab, 0 ≤ x ≤ W is one dimensional. However, if one of the edges, say x=0, is rough the conduction will be two dimensional. The two dimensionality varies with the correlation length with a maximum at a length approximately 10% of the slab width. ... Read More

Viscous damping of a periodic perforated MEMS microstructure when the Reynolds’ equation cannot be applied: Numerical simulations

D. Homentcovschi[1], and R.N. Miles[1]
[1]Department of Mechanical Engineering, SUNY Binghamton, NY

This paper develops a computational model for determining the total damping coefficient for a unit cell of a MEMS microscale device containing a repetitive pattern of holes. The basic cell of the microstructure is approximated by an axi-symmetric domain and the velocity and pressure ... Read More

Finite Element Analysis of Thermal Fatigue in Thermal Barrier Coatings

U. Bardi[1], C. Borri[1], A. Fossati[1], A. Lavacchi[1], and I. Perissi[1]
[1]Dipartimento di Chimica, Università degli Studi di Firenze, Sesto Fiorentino, FI, Italy

A Finite element model of plasma sprayed TBC’s was developed to estimate the stress induced by thermal cycling experiments. A heat transfer analysis was performed to evaluate the temperature distribution on the specimen during the cooling under an impinging air jet; temperature ... Read More

Importance of Assembly Discontinuity Factors In Simulating Reactor Cores Containing Highly Heterogeneous Fuel Assemblies

G. Gomes[1]
[1]Atomic Energy of Canada Limited, Mississuaga, Ontario, Canada

To assess the importance of assembly discontinuity factors (ADF), a highly heterogeneous reactor core was simulated using a COMSOL model in which ADF are not used. The resulting errors in assembly powers were found to be unacceptably high. This indicates that for highly heterogeneous ... Read More

Thermal Design of Power Electronic Devices and Modules

N. Delmonte[1], M. Bernardoni[1], P. Cova[1], and R. Menozzi[1]
[1]Dipartimento di Ingegneria dell’Informazione, University of Parma, Parma, Italy

This work describes a way to apply 3D Finite Element Analysis (FEA) to the thermal design of power electronic modules using simplified geometry models of the system components. The method here presented can overcome the problem of solving equation systems with a very high number of ... Read More
