This article describes work carried out at Imperial College, London, in which a variety of gamma and X-radiography techniques were applied to the study of flows with two liquid phases (i.e., liquid-liquid two-phase flows and liquid-liquid-gas three-phase flows). Using a series of single-beam, single-energy gamma densitometers, it was possible to obtain data on the evolution of slug velocity and frequency. Using a traversing-beam, dual-energy densitometer, it was possible to obtain tomographic data on average phase distribution and (by conditional sampling) the phase distribution in the slugs. Using a triple-beam, dual-energy gamma densitometer, it was possible to obtain transient phase distribution data in the cross section, though at limited locations. Finally, complete cross-sectional distributions of the phases were obtained using a multibeam X-ray system, again in a form suitable for interpretation using a tomographic algorithm.
