Numerical Analysis of Electrical Field characteristics and Parameter Optimization for Electrical Capacitance Tomography System of Oil/water Two-phase Flows

The principle of electrical capacitance tomography (ECT) is introduced, and the simulation based on the finite element method (FEM) about the sensitivity distribution of 12-electrode capacitance transducers for oil and water two-phase flow system is discussed. Unequal mesh spacings are adopted in automatic plotting and the influence that the structural parameters of transducers impose on the performance of ECT is studied. The optimum design of transducer is achieved to improve the performance of transducers based on the given optimum function by the method of finite element and orthogonal test design, which offers reference for the design and development of transducers.
