Two-Phase Flow Patterns Identification Based on Eztension Matter Element
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 e-valuated 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.
