Flow pattern identification based on a single-wire capacitance probe

To identify flow patterns in horizontal gas-liquid flows,a single-wire capacitance probe was used for voltage output for the first time. Regardless of the measurement accuracy of water layer height, the statistic parameters of the voltage-time traces were compared within the same sampling time of 5 s under different flow patterns, including maximum, minimum, range, and average. The results show that most of flow patterns were accurately identified except for some transition lines. (authors)
