The energy pay back is one of the most interesting field especially in the steel industry where this contribution is strictly connected to steams and emissions inside and outside the plant. Perhaps, this application is sometimes disturbed by a strong variation of emissions (\"off gas\"). ... En savoir plus

In the manufacturing of high voltage electrical equipment, an important step to guarantee a right dielectric design can be carried out through the prediction of a possible occurrence of the corona effect or, in the worst case, of dielectric breakdown, preferably in early stages. For this ... En savoir plus

This talk is for users of the COMSOL Multiphysics® software who, like the present author, are relative newcomers to numerical simulation but have a strong grounding in Hydrodynamics or related areas of Mathematical Physics. As part of a multi-year plan to develop proficiency in Equation ... En savoir plus

The paper addresses a class of problems for modeling and consequently simulating the electromagnetic field radiation pattern from a two arm Archimedes spiral coil. The performance of particular interest is knowledge of the radiated magnetic field H and electric field E in the ... En savoir plus

An simple analytical model for the calculation of the resonance frequency of coils typical consists of a network of inductance, capacitance and resistance. Calculating these three parameters based on spatial geometry is not easy in most cases. The finite element method as used in COMSOL ... En savoir plus

Finite element analysis provides new insights into the electrical behavior of conducting adhesives. We show that at a contact between a spherical conducting particle and a flat conducting substrate the current distribution is non-uniform: the current is concentrated at the periphery of ...

Electrospray Deposition (ESD) is a process used in manufacturing that utilizes a charged capillary to disperse a flowing liquid into a spray that deposits onto a grounded target substrate. The build-up of charge on the substrate can begin to deflect further spray, allowing the material ... En savoir plus

In this poster, a numerical model of spot pulsed current TIG welding for partially and fully penetrated weld pools is presented. Heat transfer and fluid flow in the weld pool driven by the combination of electromagnetic force, buoyancy force, surface tension gradient and latent heat are ... En savoir plus

It was suggested long ago that a theoretical model of a near-cathode region in a DC glow discharge admits multiple steady-state solutions describing different modes of currrent transfer. Even the most simple self-consistent models should admit such multiple solutions. In the present ... En savoir plus
