In this study, to be based on the informations obtained from the signals of void fraction on the tube center, the flow regime and the minimum film thickness on a tube surface are discussed. The principal results are summarized as follows 1) The boundary between bubble and slug flow obtained by the flow regime is similar to the boundary obtained by the visual obsarvation. 2) The time of existing gas and the minimum film thickness strongly correlate and are invers to each other. From this point of view mentioned above, the flow conditions could be classified from the signals of void fraction on the tube center. The results are applicable to the experimental prediction of two-phase flow regimes in systems in which the visual study of inside flow condition are impossibe.
