超声层析成像监测气／液两相泡状流体分布

ULTRASOUND COMPUTERIZED TOMOGRAPHY APPLIED TO DISTRIBUTION MONITORING OF GAS/LIQUID TWO-PHASE FLUID

综述了绕射、反射和透射３种不同模式超声层析成像（ＵＣＴ）系统的原理及在气／液两相流体分布状况监测中的应用现状，详细论述了透射模式ＵＣＴ系统在气／液两相泡状流体分布状况实时监测应用中的理论描述、系统构成及算法实现．最后，在仿真研究和实验研究的基础上论述了ＵＣＴ系统的发展和应用前景．

Ultrasound Computerized Tomography (UCT) has entered a new stage in the family of Process Tomography (PT) which is playing a dominating role in the field of monitoring and controlling the industrial process parameters. In this paper presented are tomographic theorems of Diffraction-Mode, Reflection-Mode and Transmission-Mode (TM) UCT, as well as the possibility of their application to the gas/liquid two-phase fluid measurement. Then the details are discussed of TM UCT method concerning the theory, system configuration and reconstructive algorithm applied to the gas/liquid two-phase fluid. Finally, the future prospects of UCT are also given.
