摘要：
In order to be able to real-time control over the related equipments of pneumatic transportation system and to prevent plugging from happening, a method that uses an electrical capacitance tomography system and extension matter element to identify two-phase flow patterns is proposed. The extension matter element theory and extenics set are used. According to the extenics theory, the matter-elements of two-phase standard flow patterns, classical field and joint field of matter element are determined. The correlation degrees between the standard flow patterns and the flow patterns to be evaluated are calculated by correlation function. The two-phase flow patterns are identified according to the maximum subordination principle. The simulation experiment results have shown that this method has higher recognition precision in the two-phase flow pattern identification. It also provides an effective means for the two-phase flow pattern identification.
