| Summary: | This paper describes the modeling of boiling multisize bubbly flows and its application to
the simulation of the DEBORA experiment. We follow the method proposed originally by
Kamp, assuming a given mathematical expression for the bubble diameter pdf. The original model
is completed by the addition of some new terms for vapor compressibility and phase change. The
liquid-to-interface heat transfer term, which essentially determines the bubbles condensation rate
in the DEBORA experiment, is also modeled with care. First numerical results realized with the
Neptune_CFD code are presented and discussed. |
