以12电极电容层析成象(ECT)系统所重建的管截面图象为分析对象,从图象理解的角度出发,采用图象的树型拓补结构表示和模糊模式识别技术辨识两相流流型,为分相含率测量等提供先验知识。该方法可识别层状流、环状流、核心流等两相流型。
Based on the image of the tube cross section reconstructed by 12-electrode capacitive tomography (ECT) system, the two-phase flow was identified by image tree topology representation and fuzzy pattern recognition The flow pattern provides a priori knowledge of fractional phase content measurements. The method can identify stratified flow, annular flow, core flow and other two-phase flow patterns.
