基于电场中心线的ECT灵敏度矩阵计算
Sensitivity matrix generation for electrical capacitance tomography based on electrical field center lines
摘要
Abstract
Electrical capacitance tomography (ECT) was widely applied to online measurement of two-phase flows due to its high temporal resolution. However, the so-called“soft field effect”has seriously limited the imaging quality of ECT systems. To improve the quality of online imaging, the sensitivity matrix was calculated based on the concepts of electrical field center lines by referring to the generation of projection matrix used in computed tomography (CT). The proposed method was examined by experiment of two phase flow visualization, which demonstrates that the generated sensitivity matrix is suitable for online monitoring of two-phase flow and improves the spatial resolution at the central region of the sensitivity field.关键词
