| 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 twophase flow system is discussed.Unequal mesh spacings is adopted to improve the precision in calculation and the influence which the structural parameters of transducers impose on the performance of ECT is studied. |
