Abstract :
A novel approach is provided, in the linear 2-D case, for discretizing eddy-current problems in moving conductors by the finite integration technique over generic polygonal grids. An energetic approach is used both for discretizing the velocity terms and for deriving a streamline upwind stabilization scheme. The approach is validated by analyzing a rotating shaft at both small and large Peclet numbers.
