 note = {The results of an experimental investigation of liquid lump behaviors are presented for vertical upward gas-liquid two-phase flow. Liquid lumps were classified into liquid slug, huge wave, disturbance wave and ephemeral large wave by analysing time-spatial signals of cross-sectional averaged liquid holdup, which were detected at twelve locations along a 25.8mm inside diameter tube. Two types of behaviors were found for liquid slug and huge wave : one shows axilly steady movement, and the other is transient as a liquid slug rapidly disappears or drastic deformation of a huge wave occurs with time. An evaluation method for the development of cap bubble flow in liquid slug coalescence is proposed. There exist various behaviors of ephemeral large waves such as forward, backward and complicatedly direction-changing movement depending on the flow conditions. It is shown how these behaviors correspond to reverse flow length of liquid film and averaged gas length., 日本機械学會論文集. B編, 53（493）, pp.2807-2813; 1987},
