Abstract/Summary The highly turbulent air-water flows represent a major challenge in terms of mathematical and numerical modellings. Herein a detailed comparison between experimental and numerical modelling of hydraulic jumps is presented. The results highlight the interactions between physical and numerical modelling. The findings give some new insights into the complexity of the problem as well as the status of existing numerical techniques and validation methods.
