CFD simulations of GIDROPRESS mixing facility experiments

Extensive analytical work: - 65 pre-test calculations - 45 post-test calculations Comparison of all code results against exp data Main findings: - 3rd Group (steady pump operation + tracer injection) - Perturbation morphology correctly described - Quantitative discrepancies (degree of mixing) - Can be handled by proper accuracy and uncertainty evaluation 2nd Group (tracer slug + onset of NC) - Crucial role played by density effects
