Finite Element Prediction of Laser-Material Interaction Using COMSOL Multiphysics®

E.C. Chevallier [1], V. Bruyère [1], P. Namy [1],
[1] SIMTEC, Grenoble, France

Surface engineering is a key technology used in a wide range of sectors in industry. Among other techniques, it involves adding functionality to a surface. This can be performed by creating a specific topography to a surface using laser texturing. The objective of the work presented in ... En savoir plus

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

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

The Nonlocal Optical Response of Gold Nanowire

Changyin Ji [1], Qingfan Shi [1], Yongyou Zhang [1], Ning Zheng [1], Liangsheng Li [2],
[1] Beijing Institute of Technology, School of Physics, Beijing, China
[2] Science and Technology on Electromagnetic Scattering Laboratory, Beijing, China

Recently, the researchers usually use the hydrodynamic Drude model (HDM)to investigate the nonlocal optical response of metallic nanostructure. The advantage of the HDM is easy to implement numerical calculation for larger and more complex shaped nanoplasmonic structures. For the HDM, it ... En savoir plus

Harmonic and Transient Magnetic Analysis of Single Turn Coils fed by a Current Pulse at Medium Frequency

O. Maloberti [1], O. Mansouri [1], D. Jouaffre [2], D. Haye [2]
[1] ESIEE Amiens, France
[2] PFT Innovaltech, France

Single turn coils are used in pulsed magnetic technologies for which both magneto-harmonic and transient magnetic analysis are required. We suggest studying one single turn coil example made of a conducting massive coil, an optional conducting field shaper and an internal conducting tube ... 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

Modeling of Nonuniform Magnetisation of a Ferrite Loaded Waveguide

H. V. Dixit [1], A. R. Jadhav [2], Y. M. Jain [3], A. N. Cheeran [1], V. Gupta [2], P. K. Sharma [3],
[1] Veermata Jijabai Technological Institute, Mumbai, Maharashtra, India
[2] Vidyavardhini's College of Engineering and Technology, Vasai, Maharashtra, India
[3] Institute for Plasma Research, Gandhinagar, Gujarat, India

The modelling of a ferrite material is conventionally carried out using the Polder permeability tensor which assumes that the ferrite is saturated by a uniform magnetic field. This assumption is often inaccurate due to the constraints imposed by boundary conditions which renders the ... En savoir plus
