Abstract
In the framework of nuclear safety analyzes, the code RESUS is being developed for the prediction of the release of droplets and low volatile radionuclides due to bubble bursting at liquid surfaces. The code consists of three independent submodules, each simulating important submechanisms of droplet generation. The mechanistic models are explained, and results of RESUS calculations are presented. Profiles of bubbles resting at a phase interface are discussed in some detail. There is good agreement between calculated and experimentally observed shapes given in the literature. Additionally, energies relevant for re-entrainment being provided by the resting bubble are calculated. Simplified dimensionless energy correlations are derived for general use. The generation and disintegration of a liquid jet is analyzed and presented.
