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 simulationThe simulation experiment was planned by using orthogonal experimental designFrom the simulation result, the major factors influencing the sensitivity characteristics (relative sensitivity and uniformity error) were obtainedThe degree and tendency of influence of each factor on the sensitivity characteristics were givenThe structural parameters of the sensor were determinedThe analysis provided the theoretical basis for the inner and outer ring capacitance sensor.
