RESUMO

Predictions of local boiling flow processes leading to departure from nucleate boiling (DNB) conditions are considered. The work was performed within the Nuclear Reactor Simulations project (NURESIM) within the Sixth European Framework program. This paper focuses on the Reynolds-averaged Navier-Stokes (RANS) approach as being the most reliable for simulation of realistic bubbly flows. New physical models developed within the NURESIM project are presented and tested on various single-channel boiling experiments, differing in geometry, working fluid, and operating conditions. The applicability of the model for boiling in fuel rod bundles under industrial conditions has been demonstrated.
