过程成像是近年来发展起来的一种两相流/多相流测量技术,其特点是以非破坏方式获得被测目标体内部多相流体的运动状态,可为动态过程建模和在线控制提供理论和技术依据。本文以电容成像为例介绍了过程成像的原理,方法及其应用;指出了已有图像重建算法的不足。文中简述了作者提出的广义逆敏感矩阵方法的基本思路和实验结果。最后从系统的角度提出了需要解决的关键科学问题。 Process imaging is a two-phase flow / multi-phase flow measurement technique developed in recent years. Its characteristic is to obtain the motion state of multiphase fluid in the target under test in a non-destructive way, which can provide the dynamic process modeling and on-line control Theoretical and technical basis. In this paper, the principle, method and application of process imaging are introduced by taking capacitive imaging as an example. The deficiencies of existing image reconstruction algorithms are pointed out. The article briefly describes the basic idea and experimental results of the generalized inverse sensitive matrix method proposed by the author. Finally, the key scientific problems to be solved are put forward from the system point of view.
