Numerical modeling of eddy current steam generator inspection: Comparison with experimental data

This paper illustrates the application of a TRIFOU modeling to a 3D Eddy Current Testing problem. Principles of the TRIFOU modeling will be briefly presented as well as the particular modules developed for coil impedance computation. Comparisons with experimental data (on a steam generator tube with an EDM notch) Will be presented on 2 different probe movements ( a rotation around the vertical axis and a translation along the notch). The experimental results are fitting very closely with numerical results.
