RESUMO

Predictions by N. Aksan, M. Andreani, G. Analytis, G. Yadigaroglu (ETH), V. H. Ransom, K. E. Carlson (INEL), M. L. Corradini, S. Lomperski (University of Wisconsin), J. S. Duffield, G. Friz, F. Nijsing, I. Shepherd (ISPRA), J. Travis (LANL) and J. M. Cuta, D. Kim, C. W. Stewart (PNL) are compared with the experimental Data Set No. 18 (J. C. Rousseau, Multiphase Science and Technology Vol. 3, pp. 442−449, 1987) on blowdown of simple pipe geometries. It was found that the prediction capability was variable; the measured void fraction data indicated an inverted annular flow regime but this could not be predicted in the 1D calculations. More advanced calculations seem to be necessary.
