Electrostatic Fluid Structure Interaction (EFSI) on the Huygens Experiment

R. Godard [1], J. de Boer[1], N. Ibrahim[2], and G. Molina-Cuberos[3]
[1]Royal Military College of Canada, Kingston, ON, Canada
[2]University of Toronto, Toronto, ON, Canada
[3]Campus Espinardo, Murcia, Spain

The Huygens Atmospheric Structure Instrument (HASI) was designed to characterize the physical properties of the lower atmosphere and surface of Titan, the planet-size moon of Saturn. The Relaxation Probe (RP) sensor on the Huygens probe, determined the electrical conductivity in the ... Mehr lesen

A Transient Unified Model of Arc-Weld Pool Couplings During Pulsed Spot Gas Tungsten Arc Welding

A. Traidia[1], and F. Roger[2]
[1]AREVA NP, Technical Center, Saint Marcel, France
[2]ENSTA Paristech, Paris, France

Using COMSOL Multiphysics, a finite element model is introduced in this paper to describe the couplings between the welding arc and the weld pool dynamic in pulsed gas tungsten arc welding. The cathode, arc-plasma and melting anode regions are taken into account. The unified time ... Mehr lesen

Stefan's Problem: Validation of a One-Dimensional Solid-Liquid Phase Change Heat Transfer Process

D. Groulx, and W. Ogoh
Dalhousie University, Halifax, NS, Canada

A 1D phase change problem, known as Stefan’s problem, for which analytical solutions are available, is solved as a 2D problem using COMSOL Multiphysics. The PCM medium is semi-infinite, initially solid at its melting temperature Tm, and at t = 0, the wall temperature is raised to Tw > ... Mehr lesen

Finite Element Modeling of the Stress Field in a Cell-Seeded Microchannel

G. Zhu, and Y. Li
Lawrence Technological University, Southfield, MI, USA

Fluids used in biomedical microelectromechanical systems (BioMEMS) devices often exhibit very different flow behavior from those in bulk solutions, which in turn affects the behavior of cells and biomolecules in the device. In this work, we investigate an integrated microfluidic system ... Mehr lesen

Modeling of Transport and Reaction in a Catalytic Bed Using a Catalyst Particle Model

F. Allain, and A.G. Dixon
Worcester Polytechnic Institute, Worcester, MA, USA

A packed bed reactor consisting of spherical catalyst particles in a tube was simulated numerically. The steady-state pseudo-heterogeneous model consisted of a pseudo-continuum representation for the heat and mass transfer in the reactor tube. The reaction source terms were evaluated by ...

Simulation of a Magnetophoretic Device for the Separation of Colloidal Particles in Magnetic Fluids

S.K. Fateen, and M. Magdi
Cairo University, Giza, Egypt

Magnetophoresis of non-magnetic particles is the induced motion of non-magnetic particles suspended in magnetic media on the application of a magnetic field gradient. Magnetophoresis can be used in special separation devices to separate colloidal particles based on their sizes. ... Mehr lesen

Conducting Finite Element Convergence Studies Using COMSOL 4.0

M.K. Gobbert, and D.W. Trott
University of Maryland, Baltimore, MD, USA

We will show how to carry out convergence studies of the FEM error on a sequence of progressively finer meshes in COMSOL Multiphysics on the example of Lagrange elements of varying polynomial degrees, which will also bring out the benefit of using higher order elements. The sample ... Mehr lesen

Super-resolving Properties of Metallodielectric Stacks

N. Katte[1], J. Haus[1], J.B. Serushema[1], and M. Scalora[2]
[1]University of Dayton, Dayton, OH, USA
[2]Charles M. Bowden Research Center, Redstone Arsenal, AL, USA

We show that diffraction can be suppressed in a one-dimensional metallodielectric stack (MDS) at visible wavelengths to achieve super-resolution imaging. In our calculations we use two popular techniques, which can be adapted to investigate the imaging properties of MDSs. The two methods ... Mehr lesen

Numerical Simulation of a Joule Heating Problem

S.M.F. Garcia[1], and P. Seshaiyer[2]
[1]U.S. Naval Academy, Annapolis, MD, USA
[2]George Mason University, Fairfax, VA, USA

In this work we consider a 1-D mathematical model that describes a heating problem combined with electrical current flows in a body which may undergo a phase change as a result of the heat generated by the current, so-called Joule heating. The model consists of a system of nonlinear ... Mehr lesen

Modeling Microfluidic Separations Using COMSOL Multiphysics

B.A. Finlayson[1], and R.A. Shaw[2]
[1]University of Washington, Seattle, WA, USA
[2]National Research Council of Canada, Winnipeg, MB, Canada

Infrared spectroscopy can be used to identify chemicals in a stream provided the signal is strong enough. A microfluidic device is modeled here with the objective of separating serum components so as to enhance the metabolite/protein concentration ratio. Serum contains creatinine (a ... Mehr lesen
