Calculation of eddy currents in 3D thin multiply connected wall structures induced by a rotating plasma perturbation
Fundamentals of Electrical Engineering（2014）
摘要
In this paper we present a method to calculate the response of a 3D thin multiply connected wall to an external kink mode perturbation in axisymmetric tokamak configurations by using the radial basis functions collocation meshfree method. The wall response is expressed in terms of a stream function of the wall surface currents or by making use of the magnetic vector potential. Our approach has been applied to the investigation of Resistive Wall Modes in tokamaks.
