Surface current and eddy-current 3D computation using boundary integral equations techniques
Résumé
This paper is devoted to our most recent works in the domain of the high frequency eddy-currents computation. We have in fact define two classes of frequencies: high frequency and very high (also called infinite) frequency, this one beeing a limit case of the previous one:- the very high or infinite frequency formulation has been presented in previous papers since 1981. This formulation is very easy to built in, and gives approximate results with a low computing time. However the physical meaning of the results and the range of frequency in what this model could be used were not easy to understand: we give in this paper a new idea of that, using the results of the high frequency formulation;- the high frequency formulation takes into account the exponential decay of the magnetic field inside the conducting materials and the penetration of the induction field. This model has been validated by comparison with analytical calculations.
