A numerical multiphase flow model is proposed to predict the behavior and motion of entrained inclusions in liquid steel, as they enter the orifice of a LiMCA (Liquid Metal Cleanliness Analyzer) sensor for assuring steel quality. The method of measurement is based on the electric sensing ... En savoir plus
It is a fact that IEC 60287 standard introduces important errors in the computation of the armor losses of submarine three-core lead sheathed armored cables, since the twisting of phases and armor wires is not considered. This results in an overestimation of cable size, and hence its ... En savoir plus
Cylindrical grinding has become an integral part of machining of workpieces with an ultra-high precision and higher throughput. The grinding process involves the mechanical interaction of the grinding blade with the workpiece at relatively higher rotation speeds, with a higher energy ... En savoir plus
In order to improve the design of an induction furnace and to optimize the charge melting, a COMSOL Multiphysics® application is developed. This application runs a furnace model. The inductor, supplied with an alternative electrical tension, creates a variable induction field B ⃗. Due to ... En savoir plus
The axion is an excellent cold dark matter (CDM) candidate, originally proposed to solve the strong CP problem in strong interactions. A novel method to detect galactic axions is by using their conversion to electromagnetic waves from boundaries between materials of different dielectric ... En savoir plus
The Microwave Electrothermal Thruster (MET) is a space electric propulsion device that uses an electromagnetic resonant cavity within which a free-floating plasma is ignited and sustained, heating a propellant gas that is that exhausted out of a gas-dynamic nozzle. For an empty cavity ... En savoir plus
We present the results of full-waveform time-dependent finite-element modelling of coupled seismoelectromagnetic wave propagation in fluid-saturated porous media. To describe the seismoelectric response of the system a new set of equations is developed which couple the poroelasticity ... En savoir plus
The paper provides an overview of the state of art in computational electromagnetic. There are three major ar eas like Design, optimization and material selection for the electric machines. The computational tool based on finite elements is very useful and powerful field simulation ... En savoir plus
Signaling and telecommunication cables are shielded multipair twisted cables that lie along the railway and transfer railway information at low frequency (some kilohertz). Due to the electromagnetic disturbance of the railway environment, coming from high voltage conductors such as the ... En savoir plus
This work develops a methodology based on the application of finite element method in the frequency domain: the purpose is to evaluate electromagnetic parameters of a pot-core inductor. The knowledge of the electromagnetic parameter is very important for several reasons, for example it ... En savoir plus
