Simulation of an Aerodynamic Furnace for High Temperature Thermodynamic Data Acquisition

J.M. Borgard [1], A. Quaini [1], L. Soldi [1], E. Lizon [1], T. Alpettaz [1],
[1] CEA Saclay, Gif sur Yvette, France

High temperature thermodynamic data are crucial for a wide variety of applications in nuclear and aeronautic domains as well as material production processes like glass formation or casting. Contactless acquisition methods are preferred to avoid chemical interactions with the container. ... En savoir plus

Simulation of a Multicomponent Trace Gas Electric Swing Adsorption

C. Geitner [1],
[1] Fraunhofer institute, Oberhausen, North Rhine-Westphalia, Germany

Introduction: Electric swing adsorption is a promising technique for energy efficient gas cleaning and adsorbate recovery. Contrary to state of the art temperature swing and pressure swing adsorption, one can control the mass flow independently of the heat flow for desorption in an ... En savoir plus

Comprehensive Numerical Modeling of Filamentary RRAM Device

D. Niraula [1], V. Karpov [1],
[1] University of Toledo, Toledo, OH, USA

Resistive random-access memory (RRAM) is a non-volatile memory that operates via resistive switching between the insulating (OFF) and conducting (ON) states, representing the logical ‘0’ and ‘1’ binary states, in response to external bias. Attributes such as high memory density, fast ... En savoir plus

[1] Sorbonne Universités, Laboratoire d’Electronique et Electromagnétisme, Paris, France
[2] Peter Grünberg Institute, Bioelectronics, Forschungszentrum Jülich, Germany
[3] Sorbonne Universités, Laboratoire Interfaces et Systemes Electrochimiques (LISE), Paris, France

In a first approach towards application of the magnetic frequency mixing technique to microfluidic structures, microplanar coils have to be designed along with sample reservoir. For this, a COMSOL Multiphysics® electrical model along with an analytical calculation is used in order to ... En savoir plus

How Finite Element Analysis Revolutionized a 100-Year Old Equation

K. Carlson [1], J. Arle [1], J. L. Shils [2], L. Mei [1],
[1] Beth Israel Deaconess Medical Center/Harvard Medical School, Boston, MA, USA
[2] Rush Medical Center, Chicago, IL, USA

In 1901 Weiss proposed an equation predicting activation of nerve fibers by electrical stimulation, used in neuroscience and neuromodulation, which applies electric fields to modify nerve behavior in neurological disorders. Weiss’ equation is relative to geometry, electrode array, ... En savoir plus

A Partial Verification of a COMSOL® Example Problem on the Fluid-Structure Interaction in a Network of Blood Vessels

J. T. Fong [1], A. Heckert [1], J. J. Filliben [1]
[1] National Institute of Standards & Technology, Gaithersburg, MD, USA

Finite element method (FEM)-based solutions are known to contains errors and uncertainties due to at least four mathematical (M) and four physical (P) sources, namely, (M-1) mesh density or degrees of freedom, (M-2) mesh element types, (M-3) mesh quality such as mean aspect ratio, (M-4) ...

Space-time Formulation for Finite-Element Modeling of Superconductors

F. Grilli[1], F. Sirois[1], M. Laforest[1], and S. Ashworth[2]

[1]Ecole Polytechnique de Montréal, Montréal, QC, Canada
[2]Los Alamos National Laboratory, Los Alamos, NM, USA

In this paper we present a new model for computing the current density and field distributions in superconductors by means of a periodic space-time formulation for finite elements (FE). By considering a space dimension as time, we can use a static model to solve a time dependent problem. ... En savoir plus
