The objective of this study is to compare leak rate computation practices and the applied tools and software solutions. Leak rate prediction is an important aspect of the leak-beforebreak assessment, as assessing the detectability of leaks requires an appropriate understanding of a fluid’s flow through wall-penetrating cracks. In this context, the defects are postulated, and inevitable uncertainties concerning the exact geometric shape of defects are present. Therefore, the attainable accuracy of a leak rate prediction is fundamentally limited, so that complex three-dimensional numerical fluid simulations for leak flow are rare, and one-dimensional simulations are primarily used. However, the determination of the geometric shape and the influence of the surface morphology are also important aspects of the leak rate computation.
