摘要

提出了一种基于图信号排列熵的垂直管道气液两相流流型辨识方法。使用数字化电阻层析成像系统采集垂直管道气液两相流实验数据,计算每个电阻层析成像(ERT)电极测量值的幅值增量序列,提取每个幅值增量序列的图信号排列熵,并分析各个流型的流动特性,将提取的图信号排列熵作为特征输入卷积神经网络(CNN)以识别流型。结果表明:该方法能够有效识别泡状流、泡状-段塞流、段塞流,平均正确辨识率可达96.67%。

Abstract

Based on graph signal permutation entropy,a flow pattern identification method for gas-liquid two-phase flow in vertical pipelines is proposed. A digital electrical resistance tomography (ERT) system to collect vertical pipeline gas-liquid two-phase flow experimental data is used, the amplitude increment sequence of each ERT electrode measurement value is calculate, and the permutation entropy for graph signals of each amplitude increment sequence is extracted, the flow characteristics of each flow pattern is analyzed. The extracted graph signal permutation entropy is input into a convolutional neural network (CNN) as a feature to identify flow patterns. The results show that this method can effectively identify bubble flow, bubble-slug flow and slug flow, and the average correct recognition rate can reach 96.67%.
