Finite Element Modelling and Orthogonal Optimizing of Capacitance Concentration Sensor for Two Phase Flow

Yan Hua, Xu Hui, Shao Fuqun, Wang Shi (School of Information Science and Engineering,NEU, Shenyang 110006)  
A computer aided design of the capacitance concentration sensor for two phase flow was presented by finite element method combined with orthogonal design method. The finite element model of the sensor was established. The influence of modeling error and sample element change on the evaluation of sensing field uniformity was analyzed. The necessity to use a consistent mesh in optimizing process to ensure the comparability of simulation results was pointed out. An example of orthogonal optimizing design of sensor was given,the optimized sensor having a nearly uniform sensing filled and an improved performance.
