Multiphysics Modeling of a Fluorine Production Cell

J. Vukasin [1], P. Namy [2], J. Sanchez-Marcano [3],
[1] Orano Cycle, HRP, BP 16, Pierrelatte, France
[2] SIMTEC, Grenoble, France
[3] Institut Européen des Membranes – UMR 5635 - Université de Montpellier, Montpellier, France

Gaseous fluorine plays a major role in the nuclear industry since it is used to produce uranium hexafluoride, whose physical properties are the key to classical uranium enrichment processes. The fluorine production process is based on the electrolysis of an anhydrous HF-composed molten ... En savoir plus

Using COMSOL® for the Development of the UK’s Second Hyperloop Prototype

A. Jocas [1], I. C. H, Chan [1], A. Malekos [1], H. P. Chan [1],
[1] The University of Edinburgh, UK

Hyperloop is a future concept of mass transportation proposed by Elon Musk. It uses electromagnetic propulsion to accelerate a passenger or cargo pod through a low-pressure tube. HYPED, the University of Edinburgh’s Hyperloop Team has created a prototype that uses linear halbach arrays ... En savoir plus

Modeling the Hyperloop with COMSOL®: on the Design of the EPFLoop Pressurized Systems

Z. Sajó [1], L. Benedetti [1], N. Riva [1],
[1] EPFL - EPFLoop, Lausanne, Switzerland

The Hyperloop is a concept system targeting passenger transportation aiming to carry people in a pod running in a high vacuum tube at 1200 km/h. In 2015, SpaceX announced that they would sponsor a Hyperloop pod design competition, because of their interest in helping to accelerate the ... En savoir plus

The Numerical Challenges in Multiphysical Modeling of Laser Welding with ALE

I. Tomashchuk [1], I. Bendaoud [2], J.-M. Jouvard [1], P. Sallamand [1],
[1] Laboratoire Interdisciplinaire Carnot de Bourgogne, Université de Bourgogne-Franche-Comté, Le Creusot, France
[2] Laboratoire de Mécanique et Génie Civil, Université de Montpellier, France

The interaction of high power laser beam with metallic materials produces a number of interconnected phenomena that represent a serious challenge for numerical modeling, especially for creation of auto-consistent models. Additional difficulty consists in lack of data on materials ... En savoir plus

Computational Biophysics in COMSOL®: FSI-Simulations of Cells in a Microfluidic Device

L. D. Wittwer [1], S. Aland [2],
[1] HTW Dresden / TU Dresden, Germany
[2] HTW Dresden, Germany

INTRODUCTION The mechanical properties of biological cells are promising biomarkers to differentiate for example cell phenotypes, cell states or between healthy and unhealthy cells with applications ranging from research facilities to medical laboratories [1, 2]. Real-time deformability ... En savoir plus

Thermo-Fluid-Metallurgical Modeling and Parametric Study of Laser-Based Powder Bed Fusion Process

M. Bayat [1], S. Mohanty [1], J. H. Hattel [1],
[1] Department of Mechanical Engineering, Technical University of Denmark, Lyngby, Denmark

Laser-based powder bed fusion (LPBF) is a promising additive manufacturing technology, where metallic parts are produced in a layer-wise manner. At each step, a rapid-moving laser irradiates and subsequently melts predefined zones of a relatively thin layer of fine spherical metal ... En savoir plus

Application for Construction and Numerical Analysis of New Melting Elements

L. Strehar [1], S. Kovač [1], D. Janc [1],
[1] ETI d.o.o., Izlake, Slovenia

ETI is one of the world’s leading manufacturers of fuses. Different standard sizes, rated voltages, rated currents and tripping characteristics mean more than 750 different types of products. Additionally, our customers sometimes require fuses specifically designed for their needs. Our ... En savoir plus

Magneto-Mechanical-Thermal Couplings for the Pulsed Magnetic Technology with Single-Turn Coils

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

Single turn coils produce AC and transient magnetic fields in pulsed magnetic technologies for which magneto-harmonic and transient magnetic analysis can be primarily performed. We suggest studying one single turn coil example made of a conducting massive coil, an optional conducting ... En savoir plus

Design of an AC Transformer in the MHz Range

D. Martinet [1], Ch. Ellert [1],
[1] University of Applied Sciences Western Switzerland (HES-SO Valais-Wallis), Institute of Systems Engineering, Sion, Switzerland

Due to the Paschen law the ignition voltage for plasma increases proportionally to electrode gap and pressure between electrodes. Atmospheric plasmas operating in the MHz range, being of great interest for surface treatment, require therefore high voltage power supplies, even though in ... En savoir plus

Experimental Setup to Investigate the Liquid Water Content in Snow

A. Coulin [1],
[1] SLF Davos, ETH Zurich, Switzerland

Snow can exist in a wide range of temperatures. Its behavior changes especially around its melting point. A better understanding for wet snow is essential for snow pack stability, the effect of water percolation and friction between ski and wet snow surface. Technical details about ... En savoir plus
