Plasma Arc Welding (PAW) is one of the important arc welding processes commonly used in electronics, medical, automotive and aerospace industries due its high accuracy, finishing, and ability of welding any hard materials. It is an extension of Tungsten Inert Gas welding (TIG or GTAW). ... En savoir plus
INTRODUCTION: The “Schrödinger equation” is usually associated with quantum mechanics, however for the nonlinear version (NLSE), there are applications outside the realm of quantum mechanics. NLSE appears in branches of physics like a) the quantum physics Bose-Einstein condensation ... En savoir plus
This work, which is done in the framework of the SisAl Pilot EU project, presents the use of the COMSOL Multiphysics® software for simulating an ensemble averaged electric arc in a laboratory-scale electric arc furnace. The SisAl Pilot project aims at optimising the silicon production in ... En savoir plus
Europeans spend between 80% to 90% of their time indoors, for example at home, school, office, and other public buildings. Besides, due to energy-saving measures in buildings, natural ventilation is reduced leading to the accumulation of indoor air pollutants. Consequently, indoor air ... En savoir plus
Nowadays, surge protection devices are widely used in electrical grids to suppress over voltages during transient conditions caused by voltage surges and to prevent damages of industrial or household devices. The working principle is based on the initiation of an arc with a burning ... En savoir plus
Simulating the shielding of a 3T-magnetic field with superconducting NbTi and BSCCO tubes deploying the A-H field formulation using COMSOL Multiphysics Screening of electromagnetic fields is a crucial technique for areas such as telecommunications, medical imaging, data storage and for ...

ICP reactors are usually meter sized and driven at RF frequencies, for example at 13.56 MHz. We developed a miniature resonator allowing an inductive type of coupling of microwaves at 2.45 GHz to a plasma jet, flowing in ceramic tubes. Previous experiments and simulations show an ... En savoir plus
Materials such as aluminium with high thermal and electrical conductivities are of industrial interest, particularly for the automotive industry in the current context of increasing production of electric vehicles. The reflective properties of this material make it difficult to process ... En savoir plus
The ceramic metal halide lamps belong to the most efficient high intensity light sources of these days. Presently it is the nitrogen contamination that causes the most significant problems during ignition. If this material gets into the lamp's interior in high concentrations, it will ... En savoir plus
The purpose of this paper is to present a numerical modeling of plasma phenomena in beryllium emissions using COMSOL Multiphysics software. The Beryllium films were deposited on mirror polished fine grain graphite substrates using the Thermionic Vacuum Arc (TVA) technology available at ... En savoir plus
