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