Abstract:Fuzzy entropy algorithm is a new approach that is proposed based on approximate entropy and sample entropy. In this paper, we use these three methods to analyze the characteristics of flow patterns of gas-liquid two phase flow, and the approximate entropy and sample entropy are also employed as comparison. The study shows that relative to the approximate entropy and sample entropy, the fuzzy entropy method has better gathering results, it can distinguish the three typical flow patterns clearly. This provides a new way for the study of gas-liquid two phase flow. © 2015 Technical Committee on Control Theory, Chinese Association of Automation.
