Abstract: Abstract Recently, an unusual scaling law has been observed in circular hydraulic jumps and has been attributed to a supposed missing term in the local energy balance of the flow (Bhagat et al., J. Fluid… read more here.

DOI: 10.1017/jfm.2023.346
Abstract: Abstract We consider a special type of hydraulic jumps (internal bores) which, in the vertically bounded system of two immiscible fluids with slightly different densities, conserve not only the mass and impulse but also the… read more here.

DOI: 10.1061/(asce)hy.1943-7900.0001706
Abstract: AbstractA hydraulic jump is a complex, rapidly varied flow phenomenon occurring in the transition from supercritical to subcritical flows. Hydraulic jumps are characterized by instationary motions ... read more here.

DOI: 10.1139/cjce-2017-0462
Abstract: Hydraulic jumps on a large scale are turbulent, with high Reynolds number. It has been proven difficult to achieve this in previous studies of jumps as two-phase flow. This paper aims to investigat... read more here.
