摘要：
In this work simulations of 4 DEBORA experiments have been performed with ANSYS Fluent code in Eulerian two-fluid framework, using the standard wall boiling model. The cases varied by their inlet sub-cooling and consequently represented different boiling flow regimes. Temperature, void fraction, Sauter mean diameter and velocity profiles were compared with the experimental data. Preliminary analysis showed qualitatively good agreement of simulated-temperature and velocity profiles with DEBORA experiments, while more detailed study of boiling and inter-phase transfer parameters will be needed to better match the void fraction profiles and bubble diameter profiles. Mainly the simulated Sauter mean diameters also significantly over-estimated the measured values in the near-wall regions.
