Flow pattern is one of very important flowing parameter in two phase flow
and the flow characteristic and heat transfer are much different for different flow patterns.Flow pattern also has significant effects on the parameters measurement of two-phase flow.Using the new development conductance sensor of two-phase flow
the conductance fluctuating signals is obtained from different gas/liquid two-phase flow patterns in vertical upward pipe.Dealt with the acquired signals in time-frequency domain by using Wigner-Ville distribution(WVD)
and the relationship between WVD features and flow patterns are observed.A good result of flow pattern identification is obtained.
