摘要/Abstract

摘要： 时间序列的符号动力学信息熵H_k因其计算简单快速,对数据量要求小,而被应用于非线性时间序列的分析中。将其应用于气液两相流型电导信号的分析中,首先通过其在高斯白噪声中的应用,来分析参数的选择标准。接下来讨论不同参数选择对气液两相流型识别的影响,并将流型信号的H_k-up同3种典型仿真信号进行对比。最后采用分段计算H_k-up的方法对气液两相流型电导信号进行分析,剖析了各种流型的演化规律。分析结果表明:符号动力学信息熵是一种有效的分析气液两相流电导信号的方法,能够有效区分不同流型,并能够反映不同流型的演化规律特性。

Abstract: The dynamics Shannon entropy H_kof the signal of time series is applied to nonlinear time series analysis because of less data demand and simpler calculation.It was used to analyze the signals of two-phase flow conductance.Firstly,the selection criteria of the parameters were analyzed through the application in white Gaussian noise.Secondly,the effect of different parameters in the two-phase flow pattern identification was discussed,and the H_k-up of flow pattern were compared with three typical simulated signals.Finally,the signals of two-phase flow conductance were analyzed by calculating the segmented H_k-up,and the evolutions of various flow patterns were analyzed.The dynamics Shannon entropy was an effective method for the analysis of two-phase flow conductance signals,different flow patterns could be distinguished and the evolution characteristics of different flow patterns could be identified.

Key words: symbolic dynamic, gas-liquid two-phase flow, flow patterns identification, entropy
