Differential pressure fluctuations are used to estimate flow regimes of nitrogen gas-water mixtures in a vertical pipe because the fluctuations seem to be closely connected with the flow configuration. The regimes of vertical two-phase flow are classified by the peculiar features of statistical properties of the fluctuations, which are calculated from the data of static pressures measured at four locations along the flow direction. The results show that it is possible to identify the flow pattern from the configuration of probability density functions, the order of variance and th average value of differential pressures because these statistical properties depend on a flow pattern.
