Time-series information on both the cross-sectional mean liquid holdup along the tube axis and the gas-liquid phase distribution along a tube diameter was obtained by means of supermultiple-cross-sectional holdup probes (S-CHP) and semi-supermultiple-point-electrode probes (SS-PEP) for vertical downward gas-liquid two-phase flow. Typical time-spatial maps of wave behavior and gas-liquid interfacial profiles are presented. Close inspection of these results reveals that huge waves and disturbance waves appear in downward two-phase flow as well as upward flow. It was clarified that huge wave flow region covers a wide range of superficial gas velocity. Wave velocity, wave width and maximum liquid holdup of individual waves were examined by means of a wave-vein analysis. Probability distributions of these flow parameters were also investigated. It was found that there exist distinct differences in wave width and maximum liquid holdup between huge waves and disturbance waves.
