Review on tomography technologies in multiphase flow

As tomography imaging technology can obtain two-dimensional/ three-dimensional space-time local multiphase flow distribution information.It is one of trends and frontiers for detection of multiphase flow parameters.The research status at home and abroad on appling electrical resistance tomography,electrical capacitance tomogrphy,ray computed tomogrphy and ultrasonic tomogrphy technologies to measure multiphase flow parameters and the development of tomography technologies in multiphase flow applications are described systematically in this paper.
