摘要：

The feasibility and potential of applying capacitively coupled contactless conductivity detection ((CD)-D-4) technique to flow pattern identification of gas-liquid two-phase flow is investigated. Conductivity signals of two-phase flow are obtained by a (CD)-D-4 sensor, and flow pattern identification is implemented by using SVM method. Experimental results show that the identification accuracies of five typical flow patterns (stratified, wavy, bubbly, slug and annular flow) are satisfactory. This preliminary work verifies that (CD)-D-4 is an effective way to implement online flow pattern identification of gas-liquid two-phase flow and it may have a broad perspective in related industrial field.
