电容层析成像(ECT)系统阵列传感器的访真研究

Study of capacitance tomography sensor framwork

电容层析成像是监测两相流动的一种新技术.它可重建两相流在其流经管道横截面上的相分布图像,而重建图像的先决条件是需获得成像系统的灵敏场分布.研究表明,电容传感器的结构参数对电容敏感场灵敏度的分布有重要影响,进而影响着重建图像的质量,因此电容传感器结构参数的优化设计是极其必要的.介绍了ECT阵列传感器的结构参数仿真试验,并据此对电容层析成像系统阵列传感器进行了优化设计.

Capacitance tomgraphy is a new technique for monitoring two-phase flow that can reconstruct cross-sectional phase distribution images of the pipeline through which two-phase flow runs,and the sensitivity distribution of the tomography system must be defined before the image reconstruction.The result of the research indicates that the structural parameters of ECT tomography system affect the sensitivity distribution highly,therefore,also affect the quality of the image reconstruction.It is quite necessary to...
