Plasma inductive torch is a complex multi-physic problem involving fluid
dynamic, electromagnetism and radiation equations. The present talk is
especially dedicated to the electromagnetic part of the problem when we
deal with several couplings between the eddy-current, the thermal and
the electromagnetic fields. After a short presentation od the global
problem, we give the numerical modelling based on a finite element
method.The main difficulty we highlight in the talk is a precise
description of the fields when employing very high frequencies such as
64 Mhz usually employed in experimental set-up. |
