Suitability of drift-flux models, void-fraction evolution and 3D flow pattern visualization during stationary and transient flashing flow in a vertical pipe

Manera, A.; Prasser, H.-M.; van der Hagen, T. H. J. J.


An assessment of void fraction correlations and drift-flux models applied to stationary and transient flashing flows in a vertical pipe has been performed. Experiments have been carried out on a steam/water loop that can be operated both in forced and natural-circulation conditions. Advanced instrumentation, namely wire-mesh sensors, has been used to obtain a detailed picture of the void-fraction development in the system. On the basis of experimental data collected, three-dimensional flow-pattern visualization was achieved.
