Assessment of GEN-I DNB models against data from the Argonne National Laboratory/Slug Flow/Boiling

I work on developing new approaches for the computational modeling of slug flow regime (large complex elongated bubbles) using Computational Fluid Dynamics (CFD) for Eulerian-Eulerian (statistical) approach using high fidelity Volume of Fluid (VOF) simulations where the interface of the bubbles is tracked. This is extremely important for the boiling phenomena which can occur in a nuclear reactor, not only in normal operating conditions, but also during accident scenarios, as it occurred in the depressurization case at the Fukushima nuclear accident. I also work on assessing the so-called Generation I (GEN-I) Departure from nucleate boiling (DNB) models against data from the Argonne National Laboratory. My work is supported by the Department of Energy (DOE) sponsored Consortium for Advance Simulation of Light Water Reactors (CASL). I also work on the management of international cooperation and projects with the Helmholtz-Zentrum Dresden-Rossendorf in Germany, and the Politecnico of Torino in Italy.
