Abstract: This paper describes the development of ultrasonic computerized tomography for identifying the liquid and gas flow regimes. The work reported in this paper demonstrates image reconstruction techniques applied to an experimental vessel using non-invasive technique. The investigations were based on the transmission and the reception of ultrasonic sensors that were mounted circularly on the surface of an experimental vessel. The algorithms used to reconstruct the concentration profile for two-phase flow using fan-shaped beam scanning geometry were also presented.


Keywords: Ultrasonic imaging, Fluid flow measurement, Image reconstruction
