Time-spatial measurements of liquid holdup distribution along the tube axis were carried out over the length of 1325 mm in upward two-phase flow. In order to clarify the characteristics in behaviors of ephemeral waves, a method for determining sub-wave-veins, which were the traces of ephemeral waves on the time-spatial behavior charts of interface, was developed. This method was applied to the flow conditions in two regimes of huge wave flow and annular flow, and the sub-wave-veins in these flow regimes were successfully determined. Time-spatial behavior charts of interface with the determined sub-wave-vein were systematically presented and the characteristics of sub-wave-veins were discussed. Close inspection of the behaviors of sub-wave-veins reveals that there are two-types of ephemeral waves ; namely one has a shorter life span and the other has a longer life span during which causing absorption and discharge of small ephemeral waves.
