Abstract

To overcome the difficulty of discretization in considering the very thin penetration depth due to the skin effect, the 3D eddy current field problem formulated in cylindrical coordinates is solved by the longitudinal component method together with the discrete Fourier transform. Galerkin´s finite element method is used to calculate the 3D heat transfer problem in a moving conducting and permeable shell of infinite length. The results show that, with the eccentric inductor, inhomogeneous induction heating is clearly achieved
