摘要
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。
With the image of the tube section re-established by 12-electrode electric capacitance tomography (ECT) system as the object of analysis and based on the understanding to the image, the two-phase flow is recognized by using tree type topologic structure presentation and fuzzy recognition technology. This provides a priori knowledge for the measurement of phase-based content ratio. The method can recognize some of the two-phase flow types such as laminar flow, ring flow and kernel flow, etc..
