Formatted Abstract/Summary
On a stepped spillway, the steps contribute to some dissipation of the turbulent kinetic energy, while free-surface aeration can be very intense. The aim of this study is to investigate the two-phase flow properties on a gabion stepped spillway, including both free-surface and seepage flows, as well as the bubbly flow interactions at the gabion interface. Detailed measurements were conducted in a relatively large-size gabion stepped chute model. Using a combination of high-speed video movies and phase-detection probe measurements, the aeration processes in the step cavities and within the gabions were documented. The observations showed some very strong air-water interactions between seepage and step cavity flows. The results indicated a high level of interactions between two-phase seepage and cavity flows.
