Computing Surface Acoustic Wave Dispersion and Band Gaps

R. Westafer [1], S. Mohammadi [1], A. Adibi [1], W. Hunt [1]
[1] School of Electrical and Computer Engineering, Georgia Institute of Technology, Atlanta, GA, USA

The dispersion of surface acoustic waves (SAWs) has long been studied for diverse applications ranging from seismic waves to microelectronic filters. In this work, we apply COMSOL Multiphysics software for the finite element investigation of SAW dispersion in two inhomogeneous ... En savoir plus

COMSOL in the Academic Environment at USNA

K. Mcilhany[1], and R. Malek-Madani[2]
[1]Department of Physics U. S. Naval Academy, Annapolis, Maryland, USA
[2]Department of Mathematics, U. S. Naval Academy, Annapolis, Maryland, USA

The U.S. Naval Academy has used COMSOL as a research tool for many years. Academic usage of COMSOL for student use has only begun in the last five years. Student involvement comes in four types, course-wide usage, focused course related work, student projects and semester-long research ... En savoir plus

Modeling the Bacterial Clearance in Capillary Network Using Coupled Stochastic-Differential and Navier-Stokes Equations

A. Atalla[1], and A. Jeremic[1]
[1]McMaster University, Hamilton, Ontario, Canada

The capillary network is a complex-interconnected structure. A single blood cell traveling from the arteriole to a venule via a capillary bed passes through, on average, 40−100 capillary segments. The cardiovascular systems responsible of delivering blood to the tissue under sufficient ... En savoir plus

Simulation of the Turbulent Flow in HEV Static Mixers : Mixing of Ethanol with Gasoline

A. Eissa[1]
[1]Department of Chemical Engineering, Cairo University, Giza, Egypt

Mixing is a typical unit operation that occurs almost in all chemical industries. Static – alternatively termed motionless – mixers are being widely used due to their low power consumption, low capital investment, minimal maintenance costs and versatility. The traditional helical mixing ... En savoir plus

Designing Polymer Thick Film Intracranial Electrodes for use in Intra-Operative MRI Setting.

G. Bonmassar[1], and A. Golby[2]
[1]AA. Martinos Center, Massachusetts General Hospital, Charlestown, Massachusetts, USA
[2]Department of Neurosurgery, Brigham and Women’s Hospital, Boston, Massachusetts, USA

A new type of MRI compatible intracranial electrode based on Polymer Thick Film (PTF) is presented and studied using COMSOL Multiphysics. The geometry considered was a two-dimensional cross section cut of 5 mm thick electrodes with 5 cm leads on top of a 2×10 cm slab representing ... En savoir plus

Boundary conditions in multiphase, porous media, transport models of thermal processes with rapid evaporation

A. Datta[1], and A. Halder[1]
[1]Biological and Environmental Engineering, Cornell University, Ithaca, New York, USA

In modeling of thermal processing of biological materials with rapid evaporation, it is critical to provide boundary conditions consistent with the phenomena happening at the surface to accurately predict spatial temperature and moisture content for quality and safety assurance. Boundary ... En savoir plus

Two-dimensional Analysis of Triple Coupled Physics of Structural Mechanics, Diffusion and Heat Transfer in a Gas Pipe

P. Lee-Sullivan[1], and M. Haghighi-Yazdi[1]
[1]Department of Mechanical and Mechatronics Engineering, University of Waterloo, Waterloo, Ontario, Canada

In this study, a 2-D model has been built using COMSOL Multiphysics® to analyze a triple coupled physics problem involving simultaneous gas diffusion, heat transfer, and structural mechanics in a pipe due to the flow of high-pressure carbon dioxide. The problem geometry and boundary ... En savoir plus

Magneto-hydrodynamic Flow in Electrolyte Solutions

M. Qin[1], and H. Bau[1]
[1]Department of Mechanical Engineering and Applied Mechanics, University of Pennsylvania, Pennsylvania, USA

The paper presents and compares two models for simulating magneto-hydrodynamic flow of RedOx electrolyte in a conduit patterned with circular pillars. The first model solves the coupled Nernst-Planck and Navier-Stokes equations subjected to Butler-Volmer electrode kinetics and provides ... En savoir plus

The Role of COMSOL Toward a Low-Enriched Uranium Fuel Design for the High Flux Isotope Reactor

J.D. Freels[1]
[1]Oak Ridge National Laboratory, Oak Ridge, Tennessee, USA

Design and safety analyses are underway to convert the High Flux Isotope Reactor (HFIR) at the Oak Ridge National Laboratory (ORNL) from a high-enriched uranium (HEU) fuel to a low-enriched uranium (LEU) fuel. The primary constraint for the project is that the overall fuel plate ... En savoir plus

Multiphysics Topology Optimization of Heat Transfer and Fluid Flow Systems

E. Dede[1]
[1]Toyota Research Institute of North America, Ann Arbor, Michigan, USA

This paper is focused on topology optimization of heat transfer and fluid flow systems for multiphysics objectives. Specifically, COMSOL Multiphysics software is coupled with a method of moving asymptotes optimizer in a custom COMSOL / MATLAB script. Various physical process including ... En savoir plus
