High Voltage Direct Current transmission (HVDC) is a suitable alternative for long distance transmission. During the years, the use of this technology has been increasing, which is one of the several reasons to improve methodologies in HVDC grounding systems. Unlike the usual approach ... En savoir plus
Medium- and high-voltage circuit breakers and reclosers are important grid protection devices that connect different grid sources and increase the network/grid reliability. Currently, there is a clear need of increasing the numbers of switching operation. Therefore, the optimal design of ... En savoir plus
At present, no 3D transient magnetic and electric fields formulation with strong eddy currents and high electric fields is available in the physical applications with COMSOL Multiphysics® software. However, some industrial products need such a tool, as it is the case for induction coils ... En savoir plus
Loudspeaker drivers are energy transducers: their main goal is to efficiently convert electrical energy to acoustic energy (sound), through the movement of mechanical parts. As such, they are prime candidates for the application of multiphysics methods and tools. The talk will outline ... En savoir plus
The versatility of COMSOL Multiphysics® software has positioned it at competitive levels against other considered industrial-standard engineering software tools. This contribution is directed towards emphasizing the need of further developing the basic concepts of this versatile tool in ... En savoir plus
Magneto-Hydrodynamic (MHD) power generation systems were originally investigated starting from the fact that the interaction of a plasma with a magnetic field must take place at much higher temperatures than could be observed in a mechanical turbine. The main problems of traditional MHD ... En savoir plus
