Abstract/Summary A hydraulic jump is a rapidly-varied flow associated by large and rapid fluctuations of its two-phase properties. Herein a miniature total pressure probe was used simultaneously with a phase-detection probe and several acoustic displacement meters to characterise the instantaneous air-water turbulent properties and the free surface fluctuations. New laboratory experiments were performed for a range of Froude numbers (3.8 < Fr1 < 8.5). The total pressure was measured within the turbulent shear region showing maximum mean pressure and maximum pressure fluctuations slightly above the invert. The interactions between the instantaneous total pressure, void fraction and free-surface fluctuations were detailed based upon some correlation analyses. Altogether the experimental method provided a greater level of details into the instantaneous two-phase flow properties, highlighting the large and rapid fluctuations of the two-phase flow properties at the millimetric and sub-millimetric scales.
