[1]Mechanical & Materials Science Engineering, Florida International University, Miami, Florida, USA

Output performance of an implantable enzymatic biofuel cell (EBFC) with three- dimensional highly dense micro-electrode arrays has been simulated with a finite element analysis approach. The purpose of this research is to optimize the orientation of this EBFC chip inside a blood artery ... Read More

Modeling Flow of Magnetorheological Fluid through a Micro-channel

N.M. Bruno[1], C. Ciocanel[1] and A. Kipple[2]
[1]Department of Mechanical Engineering, Northern Arizona University, Flagstaff, Arizona, USA
[2]Dept. of Electrical Engineering and Computer Sciences, Northern Arizona University, Flagstaff, Arizona, USA

This paper presents the approach taken through the utilization of COMSOL Multiphysics 3.5a, to develop a model that simulates the flow of a magnetorheological (MR) fluid through a micro-channel. The model was developed as an aid in the analysis of a micropump that produces flow by means ... Read More

An Analysis of Skimboard Hydrodynamics

N.D. Barnett[1], and E. Gutirrez-Miravete[2]
[1]General Dynamics-Electric Boat, Kingston, Rhode Island, USA
[2]Rensselaer at Hartford, Hartford, Connecticut, USA

This paper report on a study of the hydrodynamics of skimboards and surfboards using the computational fluid dynamics (CFD) module in COMSOL. The study analyzes the flow in a thin water layer underneath a skim board in a 2-D Cartesian coordinate. Three different sets of boundary ... Read More

Modeling Contact Line Dynamics in Evaporating Menisci

J. Plawsky[1], A. Chatterjee[1], and P.C. Wayner Jr.[1]
[1]Department of Chemical and Biological Engineering, Rensselaer Polytechnic Institute, Troy, New York, USA

The Constrained Vapor Bubble is a fundamental fluid mechanics experiment that is scheduled to run aboard the International Space Station starting in August 2009. The experiment is focused on looking at evaporation and condensation processes at the contact line, where vapor, liquid and ... Read More

An Analysis of Heat Conduction with Change of Phase with Application to the Solidification of Copper

J. Michalski[1], and E. Gutirrez-Miravete[2]
[1]Hamilton-Sundstrand
[2]Rensselaer at Hartford, Hartford, Connecticut, US

The goal of this study was to determine the possibility of using the finite element in COMSOL Multiphysics program to obtain a high accuracy solution to a moving boundary problem, specifically, the solidification of copper. A one-dimensional geometry in Cartesian coordinates was used to ... Read More

Hydro-Mechanical Response of Sedimentary Rocks of Southern Ontario to Past Glaciations

O. Nasir[1], M.Fall[1], T.S. Nguyen[1,2], and E. Evgin[1]
[1]Department of Civil Engineering, University of Ottawa, Ottawa, Ontario, Canada
[2]Canadian Nuclear Safety Commission (CNSC), Ottawa, Ontario, Canada

The last glacial cycle in the Northern Hemisphere started approximately 120,000 year ago. During that cycle, Southern Ontario was buried under a continental ice cap, with a maximum thickness of up to 3km. The ice cap retreated approximately 10,000 years ago. The COMSOL Multiphysics code ... Read More

Explicit Dosimetry for Photodynamic Therapy; Singlet Oxygen Modeling based on Finite-Element Method

Ken Kang-Hsin Wang[1], and Timothy C. Zhu[1]
[1]Department of Radiation Oncology, School of Medicine, University of Pennsylvania, Philadelphia, PA, USA

Singlet oxygen (1O2) is the major cytotoxic agent during type-II photodynamic therapy (PDT). The production of 1O2 involves the complex reactions among cancer agent, oxygen molecule, and treatment laser light. The light propagation in tumor tissue is described by the diffusion equation. ...

Electromagnetic Wave Simulation in Fusion Plasmas

O. Meneghini[1], and S. Shiraiwa[1]
[1]Plasma Science and Fusion Center, Massachusetts Institute of Technology, Cambridge, Massachusetts, USA

COMSOL has been used to model the propagation of electromagnetic waves in fusion plasmas. For the first time, a finite element method has been used to solve the wave propagation for realistic fusion plasma parameters in the lower hybrid and ion cyclotron frequency ranges. Moreover, for ... Read More
