Abstract :
A simulation method is developed to characterize the influence of the tape application method on the resin permeability of mica tape based insulations. The method is based on the finite element solution of the standard Darcy porous media flow equations. It is shown that the two-dimensional periodic cell can be used to describe the tape application method. From a simulated flow experiment, an effective permeability K* is derived which characterizes the case of impregnation. The dependence of K* on bandwidth, relative layer position and degree of lap is investigated
