| Abstract: | 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. The optimal function is presented based on sensitivity distribution which plays an important role in image reconstruction. The influence which the structural parameters of transducers impose on the performance of ECT is studied and the parameter optimizing is achieved by employment orthogonal design method combined with FEM. |
