电容式两相流相浓度传感器的模化与优化

The modelling and optimization of the capacitance concentration transducer for two-phase flow

采用有限元法对电容式两相流相浓度传感器进行了计算机辅助设计,建立了电容传感器的有限元模型,分析了模化的误差来源,探讨了如何在优化过程中避免模化误差的影响,给出了优化示例。对两相流的几种典型流型进行了仿真。

A computer aided design by finite element method of the capacitance con-centration transducer for two-phase flow is presented in this paper. The capacitance transducer finite element modelling is established, the modelling error source is analyzed. How to avoid the modelling error influence in optimizing process is discussed. The optimiz-ing example is given. Several typical regimes or component distribution is simulated.
