Acoustic data are presented for horizontal intermittent slug flows of air-water mixtures and vertical flows of sand-water suspensions. For the suspensions, glass beads were used to simulate the solid content. The ultrasonic apparatus consisted of one pulse-echo transducer and three receivers. For the intermittent flows, the ultrasonic apparatus was used together with simultaneous high-speed filming. Data were then obtained for the acoustic attenuation and transit time. Variations in these parameters as a function of solid concentration were compared with data in the literature. For the intermittent flows, the bubble / liquid slug transitions were detected using the ultrasonic data. It was then possible to calculate parameters related to the flow structure.
