JP2Identification of gas-liquid two-phase flow pattern is widely concerned in the field of multiphase flow research. The relevant method has been used extensively in multiphase flow metering. Many sets of differential pressure fluctuating signals of gas-liquid two-phase pipe flow are obtained by a multiple transducer system via a general multiphase flow experimental facility. Cross correlation functions are computed, and some flow patterns are identified with fuzzy mathematics theory. The results show that this method is feasible.
