COMPARISONS WITH PREDICTIONS WITH EXPERIMENTAL DATA SET NO. 21: LEVEL SWELL DURING VESSEL BLOWDOWN
ABSTRACT
Predictions by R. Kirmse, P. K. Malhotra (GRS), M. Andreani, N. Aksan, G. Analytis, G. Yadigaroglu (ETH), V. H. Ransom, K. E. Carlson (INEL), J. S. Duffield, G. Friz, F. Nijsing, I. Shepherd (ISPRA), M. L. Corradini, S. Lomperski (University of Wisconsin), J. C. Rousseau (Grenoble) and M. Hirano, T. Watanabe, H. Kamo, H. Osaki, H. Inoue, F. Tanabe, M. Akimoto (JAERI) are compared with the experimental Data Set No. 21 (G. L. Sozzi, Multiphase Science and Technology Vol. 6, pp. 167−211, 1992) on level swell during vessel blowdown. The pressure decay was well predicted but results for void fraction (level swell) show variable agreement. This may partly reflect the different modelization scheme used. This paper concludes with overall conclusions and recommendations regarding the physical benchmarking exercise.
