Modelling of Catalytic Radiant Heaters

J.P.Mmbaga, T.M. Mannan, N. Joederi, S.E. Wanke, and R.E. Hayes
University of Alberta

In this work we present the modelling of catalytic radiant heaters. The presentation outlines the mathematical model as well as a Laboratory setup of a catalytic radiant heater.

3D Scanning for simulations

N. Nuar
Rutgers University

In this work, we present the principles of 3D scanning. 3D scanning is the process of taking an object in the real world and through finding the relative phase in camera coordinates and projector coordinates, produces a 3D model.

Modeling Electrochemical Systems with Multiphysics

R.E. White
University of South Carolina

In this presentation we introduce the concept of Electrochemical Engineering through simulations in COMSOL Multiphysics. Our special case studies are: • a Parallel Plate Electrochemical Reactor, • a Rotating Ring Disk System, • a 3D Lithium Ion Battery, • a Portable Power System, • a Corroding Surface. These examples are all industrial ones, which shows the power of using ...

Grain Boundary Migration Model in Copper Interconnects

Tim Cale, Daniel Bentz, and Max Bloomfield, RPI

We discuss the use of 3D grain continuum modeling to study grain boundary migration driven by differences in strain energy density. COMSOL Multiphysics is used to compute stresses and strain energy densities in polycrystalline structures caused by temperature changes. We treat each grain as a single crystal, with the anisotropic elastic properties of single crystal Cu appropriately rotated to ...

Magnetic Liquids for Lab-on-a-chip and Rapid Diagnostics Applications

H. Köser
Yale University

In this presentation we outline our recent work on Magnetic Liquids, and the great number of application areas these are used. Ferrofluids are nanometer sized magnetic particles, covered by a surfactant, suspended in a carrier medium compatible with the surfactant material. Ferrofluids are applicable to a great and ever increasing number of application areas, such as: • Liquid Seals and ...

Using COMSOL Multiphysics in Advanced Engineering

Advanced Computational & Engineering Services
Columbus, Ohio

In this presentation we give a thorough introduction to advanced engineering using COMSOL Multiphysics. We introduce you to many disciplines of engineering and physics as well as multidisciplinary, multiscaled multiphysics.

Computer Modelling of Deformable non-Newtonian Flow using COMSOL Multiphysics

H.A. Lecuyer[1], F.H. Bertrand[1], P.A. Tanguy[1], J.P. Mmbaga[2], and R.E. Hayes[2]
[1] Ecole Polytechnique , Montreal
[2] University of Alberta, Edmonton

This presentation is concerned with the modelling of deformable non-Newtonian Flow using COMSOL Multiphysics. This general modelling approach has more concrete applications such as paper coating in a metering size press, meniscus location by PIDS to mention a few.

Multiphysics 2007

J. Dunec
COMSOL, Palo Alto

In this presentation we present where COMSOL Multiphysics and its modules will be in the year 2007. The presentation considers the upcoming features, not only from a developers point of view, but also through examples from different branches of applied physics and mathematics. In addition, we present some important milestones during the past 10 years for COMSOL ...

Activation Imaging of the Heart using Diffusion Models

R. Abou-Marie, and A. Jeremic
McMaster University, Canada

The inverse problem of electrocardiography involves determining information about the electrical activity of the heart from measurements on the body surface. The estimation of certain physiological parameters can potentially improve early detection of heart disease. In this study, we present an algorithm for estimating parameters that characterize the electrical activation. Estimation of ...

Effects of Nonlinear Magnetic Properties on Magnetic Bonding Forces for Magnet Array Self-Assembly

S.B. Shetye, J.S. Agashe, and D.P. Arnold
University of Florida

The objective of this researh is to develop new, magnetically-directed, self-assembly approaches to enable three-dimensional structures to be formed in parallel from a heterogeneous mixture of parts of arbitrary size and shape.
