Ultrasonic Monitoring of Gas-liquid Two-phase Turbulent Flows

Abstract

A number of demonstrative results in use of ultrasound for multiphase flows are shown. Feature of the technique is of capturing fluid interfaces in flowing state with time-resolved signal processing. For gas-liquid two-phase flows, methods of measurement for void fraction, interfaces, velocity of each phase, and volume flow rate are explained. As these extension, three-phase flow and turbidity current are also measured.
