Abstract :
To overcome the difficulty of discretization due to a very small penetration depth, the 3-D eddy current field problem is solved by the longitudinal component method together with a discrete Fourier transform (DFT) in cylindrical coordinates. Galerkin´s FEM is applied to calculate the 3-D heat transfer in a conducting and permeable moving shell. Numerical results are presented
