2121 二相流計測の昨今  [in Japanese] Progress of Two-Phase Flow Measurement  [in Japanese]

The technique of two-phase flow measurements was outlined. The time and the spatial scale of the two-phase flow measurements were discussed. Then, the relation between the scales and several typical analysis methods of the two-phase flow were explained. Two-phase flow parameters were divided into two categories; macroscopic physical parameters and microscopic physical parameters. Conceptual descriptions for 64 measurement techniques were briefly introduced.
