“…Recently, Wu and Ishii [17] pointed out that a small spherical bubble might miss one sensor of the double-sensor conductivity probe. In what follows, their correction method accounting for the missed interfaces of spherical bubbles in the application of the double-sensor conductivity probe will be described in detail [17,18].…”

“…The processing of these measurement techniques yield basically the void fraction, bubble count rate, interfacial velocity and turbulence intensity. Further information requires more advanced instrumentation : e.g., 4-or 5-sensor probes (Kim et al 2000, Euh et al 2006). …”

:In high-velocity open channel flows, the measurements of air-water flow properties are complicated by the strong interactions between the flow turbulence and the entrained air. In the present study, an advanced signal processing of traditional single-and dual-tip conductivity probe signals is developed to provide further details on the air-water turbulent level, time and length scales. The technique is applied to turbulent open channel flows on a stepped chute conducted in a large-size facility with flow Reynolds numbers ranging from 3.8 E+5 to 7.1 E+5. The air water flow properties presented some basic characteristics that were qualitatively and quantitatively similar to previous skimming flow studies. Some self-similar relationships were observed systematically at both macroscopic and microscopic levels.These included the distributions of void fraction, bubble count rate, interfacial velocity and turbulence level at a macroscopic scale, and the auto-and cross-correlation functions at the microscopic level.
