Electron beam welding process is a high-energy welding technique that uses a focused beam of electrons to join metal components. It is widely used in various industries, including aerospace, nuclear industry, automotive, and electronics, due to its ability to produce high-quality welds ... En savoir plus

Simulation of arc-wire additive manufacturing is under development in many academic and industrial sectors and at different scales. The study at the melt pool scale is often interesting to study deposition shapes and defects but not very relevant to calculate the stresses and strains at ... En savoir plus

Smouldering is flameless combustion which depends on an exothermic surface reaction occurring within a porous medium. It is harnessed by engineers to destroy organic liquid wastes in soil as the technology Self-sustaining Treatment for Active Remediation (STAR). During this remediation ... 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

Water disinfection using UV light is a well-known technology. Conventionally, mercury based cylindrical lamps are used, however, recently LED based UV lamps have emerged on a commercial scale. These devices hold several advantages compared to the conventional lamps, e.g. being mercury ... En savoir plus

Working on Faraday’s law of electromagnetic induction, electromagnetic flowmeters measure flowrate on the basis of the electric potential induced when a magnetic flux interacts with flowing water. The electromagnetic coils of the flowmeter are crucial to its operation, given that the ... En savoir plus

This paper explores the performance of a microfluidic mixer that uses a sinusoidal electric field to accelerate the diffusion process between two Newtonian liquid species in an electrolytic solution. The 2D model was developed using the Microfluidics module in the COMSOL Multiphysics® ... En savoir plus

In view of an energy system based on fluctuating renewable sources, the use of thermal energy storage (TES) systems plays a crucial role. In particular, large-scale underground water-based TES represent a promising solution as demonstrated by a number of cases currently being established ... En savoir plus

Our atmosphere, land, and water are being continuously besieged by pollutants caused by such events as heavy metals leaching from mine tailing ponds, chemical spills from railroad and truck tanker accidents, and petroleum pipeline failures, to name just a few. These environmental insults ... En savoir plus

Technical advancements in miniaturization in the last decades have, among others, brought forth the technology of so called “Lab-on-a-Chip” (LOC) systems. These systems provide the possibility to automate and accelerate certain laboratory processes, e.g., biomedical diagnostics, on the ... En savoir plus
