High Froude-number open-channel flows can entrain significant volumes of air, a
phenomenon that occurs continuously in spillways, in free-falling jets and in hydraulic …

Gas–liquid flows occur in many natural environments such as breaking waves, river rapids
and human-made systems, including nuclear reactors and water treatment or conveyance …

Aeration occurs in many natural and human-made flows and must be considered in
engineering design. In water infrastructure, air–water flows can be violent and of very high …

High-velocity air-water flows in hydraulic structures, such as spillways and low-level outlets,
are characterised by high turbulence levels and strong self-aeration. In air-water flows, the …

Hydraulic jumps are oftentimes encountered in natural and human-made environments. The
transition from supercritical to subcritical flow involves large energy dissipation rates and …

Underground flooding events are being exacerbated due to the rapid expanding of
underground space in urban and the extreme precipitation events by climate change. It is …

Free-surface aeration is a key characteristic of high-velocity flows on spillways. Despite their
common use as conveyance structures, there is a research gap in the understanding of …

Dual-tip phase-detection intrusive probes are the most widely used experimental technique
for measuring interfacial velocities in highly aerated flows. Recently, we have introduced an …

A hydraulic jump in a stilling basin at the base of spillway is typically characterized by
preaerated inflow conditions. This paper presents an experimental study of high-Froude …

Wall shear stress modification in self-aerated flows has been observed in boundary layer–
type flows mainly in the form of drag reduction. Due to its complexity, drag reduction has …
