长腰内锥与电导式传感器融合两相流测量场的特性

Field characteristic of two-phase flow measurement based on long waist cone and conductance sensor fusion

针对单一传感器难以实现两相流过程多参数测量的问题,提出一种基于新型长腰内锥差压式传感器与电导式环形传感器结合的气水两相流过程参数(流量和相含率)多传感器测量系统。应用计算流体力学和多物理场耦合分析方法,对管径为50 mm的水平管道中多传感器测量系统的流场和电场进行数值模拟,为电场与流场的耦合仿真及实验提供理论依据。

According to the difficulties measuring two-phase flow process multi-parameter with single sensor,a gas-water of two-phase flow process parameters(flow rate and phase fraction) multi-sensor measuring system was presented,which combines a new long waist cone differential pressure sensor and conductance ring sensor.The computational fluid mechanics and multi-physics field coupling analysis were used to simulate the flow field and electric field of long waist cone conductance ring sensor in horizontal pipe(DN50 mm),which provided the accurate theoretical basis for the later study about coupling simulation of the electric field and fluid field.
