Accuracy of thermal NDE numerical simulation and reference signal evolutions

Abstract

Comparison between analytical 1D and numerical 2D models is made to formulate recommendations on choosing temporal and spatial grid steps within numerical algorithms intended for solving thermal NDE problems. It is shown that accuracy in computing temperature is typically better than 10% in both sound and defect areas. Reference temperature evolutions are given for a few test situations.
