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。用自开发的有限元仿真软件包模拟计算电极对间的电容值 ,确定 12电极电容层析成像系统的灵敏场分布。
Capacitance tomography is a new technique for monitoring two-phase flow. It reconstructs the phase distribution image of the two-phase flow over its cross-section through the pipe, and the precondition for reconstructing the image is to obtain the sensitive field distribution of the imaging system. The self-developed finite element simulation package was used to simulate the capacitance between electrode pairs and determine the sensitive field distribution of 12-electrode capacitive tomography system.
