Abstract/Summary The two-phase gas-liquid flow properties of high-velocity open channel flows were studied experimentally in a large-size channel. The physical facility was equipped with a succession of triangular cavities associated with some strong interactions between air entrainment and flow turbulence. Detailed air-water flow measurements were collected with intrusive phase-detection probes for several flow conditions. The entire measurement technique was tested and a detailed sensitivity analysis was performed to assess the optimum sampling rate and duration. The new two-phase flow measurements demonstrated the high levels of turbulence in the high-speed, highly turbulent free-surface flows. These were highlighted by a strong rate of kinetic energy dissipation and dimensionless shear stress.
