Stability Analysis of ALE-Methods for Advection-Diffusion Problems

A. Weddemann, and V. Thümmler
Bielefeld University, Germany

ALE-methods are frequently used to solve systems of partial differential equations (PDEs) on moving domains. The main idea of these methods is to incorporate the time evolution of the domain into the equations. However, the motion of the domain with respect to time induces convective ... En savoir plus

Geologic Carbon Storage: Implications of Two-Phase Flow on Injection-Induced Stress on Faults

S. Prasun [1], S. Kim [2], S. A. Hosseini [3],
[1] Louisiana State University, Baton Rouge, LA, USA
[2] Department of Civil Engineering University of Nebraska - Lincoln, Omaha, NE, USA
[3] Bureau of Economic Geology, University of Texas - Austin, Austin, TX, USA

Geologic carbon storage that involves injecting carbon dioxide (CO2) into a subsurface sequestration site provides the vital approach for reducing CO2 emissions into atmosphere and thus addressing climate change issue. One challenge associated with CO2 geologic storage is that pore ... En savoir plus

Ignition Process of Microplasmas

H. Porteanu, and R. Gesche
Ferdinand-Braun-Institut für Höchstfrequenztechnik, Berlin, Germany

Microplasmas at atmospheric pressure are required in many applications, where treatments in normal ambient, with spatial resolution, are important. The interest on such miniaturized sources has increased due to the availability of a new generation of microwave sources based on high power ... En savoir plus

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 ... En savoir plus

Design Simulations of a General Purpose Research Micro Reactor for Methane Conversion to Syngas.

C. Bouchot[1], and M.A. Valenzuela[1]
[1]Instituto Politécnico Nacional-ESIQIE, México D.F, México

A general purpose stainless steel micro reactor setup for methane conversion is being designed for research purposes. We intend to design and build a modular device that would be able to manage different types of reactions depending on the installed modules. The device should be able to ... En savoir plus

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 ... 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

Finite Element Modelling and Simulation Tools for Investigation of the Process and Materials 3D-Printed by Selective Laser Melting

H. Jean Willy[1], X. Li[1], J. Ding[1]
[1]National University of Singapore, Singapore, Singapore

Selective Laser Melting (SLM), like many other additive manufacturing techniques, offers flexibility in design expected to become a disruption to the manufacturing industry. The current cost of SLM process does not favor a try-and-error way of research; which gives more room for ... En savoir plus

Numerical Study of Microfluidic Fuel Cell Performance

A. E. Khabbazi[1], A.J. Richards[1], and M. Hoorfar[1]
[1]School of Engineering, UBC Okanagan, Kelowna, BC Canada, Canada

Using COMSOL Multiphysics 3.5, a numerical model has been developed to determine the effect of the channel geometry and electrode configuration on cell performance based on polarization curves. The Butler-Volmer equation was implemented to determine the reaction rates at the electrodes. ... En savoir plus

Vibration and Noise Analysis of the Feather River Bridge

L. A. De Jesús Díaz [1], R. Daniel Costley [1], H. Díaz-Alvarez [1],
[1] Geotechnical and Structures Laboratory, U.S. Army Engineer Research and Development Center, Vicksburg, MS, USA

The U.S. Army Engineer Research and Development Center (ERDC) is conducting research using infrasound arrays to detect and monitor structures as well as for dynamic structural characterization of large infrastructure. Previous studies have determined that structures radiate acoustic ... En savoir plus
