In the development of advanced welding torches, a significant challenge lies in optimizing design and performance while minimizing costs and environmental impact. Traditionally, this has involved extensive physical testing, which is both time-consuming and resource-intensive. To address ... En savoir plus

NDIR (Non-dispersive infrared) sensors are state of the art for measuring gas concentrations in the Mid-infrared spectrum, e.g. components of exhaled human breath. These sensors require fitting light sources. Micro light bulbs and other filament based light source are sensible to ... En savoir plus

Baking is a central production step in the industrial production of edible wafers and waffles. The initially liquid batter is heated with a pair of metallic baking plates. Establishing a uniform and accurate temperature at the baking face (inner baking plate surface) is crucial for ... En savoir plus

The wide bandgap semiconductor silicon carbide (SiC) has drawn increasing attention in recent years as a promising material for high-power, high-frequency, and high-temperature operating devices. These outstanding properties of SiC make it a good candidate to replace silicon in many ... En savoir plus

Nowadays, designing ever more efficient power modules requires complex materials and more innovative methodologies. To significantly reduce the lead time of the devices and decrease the costs, especially during the prototyping and the testing phases, a Finite Element Analysis (FEA) can ... 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 ladle furnace preheating. The SisAl Pilot project aims at optimising the silicon production in Europe by recycling materials and using a carbon ... En savoir plus

Process Hardware for heating, etching and plasma deposition in vacuum processes on Silicon wafers or glass substrates face challenging requirements due to very shallow and extended structures. Molecular Flow calculations are used to evaluate staggered shields with the aim to protect ... En savoir plus

Simulation of laser processes are more and more efficient. In some cases, as welding and additive manufacturing, the physical phenomena are complex, multi-physics and multi-phases, thus some assumptions have to be done. For Laser Powder Bed Fusion, a laser beam melts and vaporizes the ... En savoir plus

The thermal load on the system components is one of the technical problems in the development of microfocus X-ray tubes. To improve their stability in long-term use, it is important to understand the physical phenomena and their influence on the system stability and filament lifetime. To ... En savoir plus

When polypropylene (PP) is produced it contains impurities in the form of dissolved gasses. These gasses can be removed by heating the material (in the form of pellets in a silo) and flushing with plenty of fresh air. However, one of the gasses is C9, which is flammable. We built a model ... En savoir plus
