Examples of Electromagnetic processes are presented: (1) cold crucible, (2) electromagnetic pump, (3) DC electromagnetic brake. A combined approach by using multiphysics modeling with Comsol and experimental validation is used in order to give some guidelines for process improvement and ... En savoir plus

Refrigeration plays a crucial role in both industrial and residential sectors, where nearly 17% of the energy consumption worldwide is related to thermal management systems [1] [2]. Furthermore, current vapor-compression refrigeration technology contributes significantly to the ... En savoir plus

A design method for BHE fields in the absence of groundwater flow is presented, based on the superposition of effects. The effects of any periodic heat load with a period of one year can be obtained by a weighted sum of the effects of a monthly unit step heat load, properly displaced in ... En savoir plus

Used for welding, cutting, deposition by projection, for the treatement of waste, or in analysis for ICP torches, for the synthesis of high purity silica or for the manufacture of nanometric powders or nanoparticules, thermal plasmas are fundamental in processing of materials and in ...

Electroformed Ni-based 3D electrodes (NiE3) offer a novel approach to enhancing alkaline electrolysis performance by increasing surface area and active sites, leading to intensified electrolysis reactions and improved efficiency. However, inefficient bubble release from the produced ... En savoir plus

FT wind sensors measure wind speed and direction using an acoustic field superimposed on a flow field in an acoustic resonator equipped with three piezoelectric transducers. The study proposed here focuses on the acoustic resonance technology of a simplified wind sensor geometry, and how ... En savoir plus

The computation of electric field strength is the state-of-the-art technique for designing and optimizing High-Voltage (HV) equipment. In this research, the equipment under analysis is Cable Termination (CaTr) which is used to apply high-voltage (75 kV – 800 kV AC) on the cable to be ... En savoir plus

The study of multiphase flows inside the microfluidic devices has received much attention recently because of its applications in heat and mass transfer, mixing, microreaction, emulsification and most importantly in MEMS and lab-on-a-chip. We study the influence of an electric field on ... En savoir plus

During the evolution of multicellularity, cells needed to find a way to self-organise into structures able to fulfil a broad range of physiological functions. Directed cell migration (DCM) is an elegant way to reorder cells and break symmetry based on simple rules and local information, ... En savoir plus

Reducing greenhouse gas emissions and finding new ecological and renewable energy sources are among the biggest challenges humanity is facing nowadays [1] [2]. At the same time, power requirements are increasing constantly, where primary energy consumption is intrinsically accompanied by ... En savoir plus
