RÉSUMÉ

Comparisons are reported between predictions and experiments for fully developed air-water flow in a vertical tube (Data Set No. 1, G.F. Hewitt and D.G. Owen, Multiphase Science & Technology, Vol. 3, pp.145-154, 1987). The participants in the calculations were M. Hirano, T. Watanabe, H. Kamo, H. Osaki, H. Inoue, F. Tanabe, M. Akimoto (JAERI), A. H. Govan, G. F. Hewitt, D. G. Owen (Harwell), A. H. Govan, P. B. Whalley (UK AEA Harwell/University of Oxford), S. Gao, D. C. Leslie (Queen Mary College, London), L. N. Persen (NTNU Trondheim). Very large discrepancies occur between the predictions themselves and between the predictions and experiments. It is concluded that taking into account waves and turbulence effects in both core and film is necessary to improve the modelling.
