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

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

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

Since the mid-1980s micro-resistivity imagers have provided borehole images using pad-type resistivity measurements. Geological features can be identified from borehole-image data, leading to improved reservoir characterisation and formation evaluation. Based either on conductive or ... En savoir plus

This study presents simulation findings from a 4-way link box assembly, aimed at understanding temperature-related challenges. The primary objective was to assess maximum temperatures within the assembly, focusing on the Complete Assembly, UET, Copper Busbar, and Wedge Link Busbar. ... En savoir plus

It is an ever desirable and challenging engineering endeavour to develop non-invasive systems for rotary machine diagnosis. Contrary to invasive methods, a non-invasive diagnostic method offers the advantages of avoiding stoppage of the machine for repairing the diagnostic system and ... En savoir plus

Induction motors have wide applications in industries, so they are prone to faults, which later result in vibrations and hence noise. So it is important to analyze the faults in induction motors, their causes, and their effect on the system. Basically, there are so many faults in ... En savoir plus
