Articles techniques et présentations

This article is the result of a hobby project. The article is going thru the iterative developing process of a claw pole machine. In this developing process, simulating the magnetic flux density and back EMF waveform have been used to validate geometrical changes to the machine. En savoir plus

For preservation of artefacts in a museum the indoor climate is often restricted to a very narrow interval for temperature, but most of all for relative humidity. In old buildings the museum conditions of artefacts, e.g. near cold walls, mostly are not in line with museum recommendations ... En savoir plus

Electroplating is a vital technology widely employed for many technological applications ranging from decorative or anti-corrosion coatings to high precision nanotechnology passive electromagnetic cloaking devices. This 2D Axisymmetric Electroplating Model demonstrates one of the ... En savoir plus

In the conference we bring together a community that is scientifically diverse in an event about the use of COMSOL Multiphysics. Oral and poster presentations highlight achievements in multiphysics modeling and simulations using COMSOL. En savoir plus

The XENON Dark Matter Experiment utilizes ultra-pure xenon (Xe) as a target for particle interaction in the effort to detect dark matter particles. To measure the purity of Xe, a gas purity monitor (GPM) is being developed which drifts electrons through Xe gas to detect impurities that ... En savoir plus

Electromagnetic micro valves are currently developed empirically or the different physics are treated separately. To accelerate the development-process and for a better understanding of the overall system, a multiphysics simulation is built up. This simulation considers the ... En savoir plus

In this paper a elastic-viscoplastic (creep) model is implemented in COMSOL 4.2a and 4.3 and benchmarked against another commercial finite element software package with a very similar material model. It is also validated against commonly performed laboratory tests such as Constant Rate ... En savoir plus

Electromagnetic actuators are a well-known field where finite element simulations are applied. Magnetic Shape Memory (MSM) actuators represent a new type of smart electromagnetic actuators where the MSM material elongates and contracts when applying a magnetic field. The MSM material ...

We present an optimized and efficient design of an electrohydrodynamic (EHD) micropump for high performance in microscale and biological applications. We are targeting two major applications, a parylene C design for electrically-actuated medicine delivery, and a silicon-based pump design ... En savoir plus

The UK Advanced Gas-cooled Reactor fleet, operated by EDF Energy, utilize a graphite core consisting of a lattice of around 3000 annular bricks. Due to irradiation, oxidation and thermal effects, the bricks deform and loose mass as they age. Of key concern is the late-life behavior of ... En savoir plus
