摘要：

Turbulent gas-liquid two-phase flows in a stirred vessel have been investigated experimentally and numerically. A double optical-fibre probe is used to measure axial gas velocities and local gas holdup, whereas a three-dimensional Lagrangian simulation of two-phase flows is used to predict the gas-liquid flow. The Lagrangian approach correctly describes the transition between the flooding-loading and loading-complete dispersion regimes, and predicts axial gas velocity, local and overall gas holdup quite well.
