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

Plasma, a complex fluid consisting of electrons, ions, neutrals, and excited species, exhibits both fluid-like behavior and electrical conductivity due to the presence of charge carriers. Consequently, computational modeling of plasma requires the integration of fluid and electrical ... En savoir plus

In the framework of the EURAMET project 16NRM05, a novel ionization gauge was developed. The goal was to develop a more stable ionization gauge that could be suitable for standardization. The AC/DC Module and the Particle Tracing Module in COMSOL® have been used to design and model the ... 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

Normally, power lines for electrical power distribution are shielded such that there is (almost) no magnetic field outside the cable. In a substation, these cables are connected to transformers via unshielded components such as switching boards and busbars. Thus, magnetic fields are ... En savoir plus

As part of its research, the Group of Electrical Engineering Paris (GeePs) uses the COMSOL Multiphysics® software for applications in an Electrical Engineering context. At present, a multitude of problems, such as artificial intelligence and the database generation that goes with it, ... En savoir plus

Efficient mixing and pumping of liquids at the microscale is a technology that is still to be optimized. The combination of an AC electric field with a small temperature gradient leads to a strong electrothermal flow that can be used for multiple purposes. Combining simulations and ... En savoir plus

In applications like nuclear reactors or particle accelerators, mechanical components near a source of radiation develop radiation damage. This typically means a change in tensile properties and fracture toughness, which depends on the radiation dose (commonly measured in ‘displacements ... En savoir plus

The synthesis of the superheavy elements and investigations of their nuclear, atomic and chemical properties are at the scientific forefront. Experiments are challenging due to the extremely low production rates and short half-lives [1]. A new universal high-density gas stopping cell ... En savoir plus

Introduction: Mechanical ventilation in the ICU can result in complications, including ventilator-induced diaphragmatic dysfunction (VIDD), leading to extended hospital stays and increased costs. This abstract presents a novel approach using multiple esophageal electrodes for phrenic ... En savoir plus
