摘要：

In order to study the multi-fractal characteristics of conductance fluctuating signals of the different flow patterns, this paper analyzes conductance wave signals of the vertical rising pipe of gas-liquid two-phase based on multi-fractal detrended fluctuation analysis (MF-DFA). By calculating wave function, generalized Hurst index, scaling function, multi-fractal spectrum parameters, the fluctuation singularity of the conductance fluctuating signals in partial and different levels was quantified in the paper. The results of the study show that: different conductance fluctuating signals have long-range correlation, and are multi-fractal process. Multi-fractal spectrum parameters can reflect the dynamic characteristics of different flow type. We can characterize the flow pattern variation of gas-liquid two-phase flow based on MF-DFA. It is a useful tool to understand flow pattern transition mechanism and its dynamic evolution character.
