Abstract
A conductance probe is used to detect the instantaneous void fraction at the centerline of a vertical tube in upward gas-liquid flow for a wide range of gas flow rates, so that various flow patterns and the transitions between them could be studied. The information was digitized and recorded for further processing, which included short-time-averaging and histograms. The results obtained were used for flow pattern recognition and for the estimation of the liquid slug holdup and its length. Certain conclusions regarding the existing two-phase flow models were drawn.
