摘要

为了设计应用于两相流相关流速测量的内外环电容传感器，优化内外环电容传感器的结构，借助有限元仿真的方法对内外环电容传感器的灵敏度特性进行分析，利用正交实验设计方法来安排仿真实验。分析仿真实验结果，得到了影响传感器灵敏度特性指标（传感器相对灵敏度和检测场均匀性误差）的主要因素以及各个因素对这两个指标的影响程度和影响趋势，优选出一组传感器的结构参数，为内外环电容传感器的设计提供了理论依据。

Abstract

In order to design the inner and outer ring capacitance sensor used in measuring the correlation velocity of two phase flow and optimize its structure

the sensitivity characteristics of inner and outer ring capacitance sensor were analyzed by using finite element simulationThe simulation experiment was planned by using orthogonal experimental designFrom the simulation result

the major factors influencing the sensitivity characteristics (relative sensitivity and uniformity error) were obtainedThe degree and tendency of influence of each factor on the sensitivity characteristics were givenThe structural parameters of the sensor were determinedThe analysis provided the theoretical basis for the inner and outer ring capacitance sensor.
