Model for polygonal hydraulic jumps [PDF]
Physical Review E, 2012 We propose a phenomenological model for the polygonal hydraulic jumps discovered by Ellegaard et al., based on the known flow structure for the type II hydraulic jumps with a "roller" (separation eddy) near the free surface in the jump region. The model consists of mass conservation and radial force balance between hydrostatic pressure and viscous ...

Experimental study of the hydraulic jump length in a smooth trapezoidal channel
Przegląd Naukowy Inżynieria i Kształtowanie Środowiska, 2022 The article showed the result of investigation of the length of hydraulic jump in trapezoidal channel. In this study, the basic factors that affect the length (Lj) and roller length (Lr) of hydraulic jump were investigated by physical trapezoidal ...

Theoretical Criterion for Stability of Free Hydraulic Jump on Adverse Stilling Basins [PDF]
Journal of Hydraulic Structures, 2014 Hydraulic jump on adverse stilling basin is an unstable phenomenon which causes some complexities in controlling of the jump. This paper considers the stability of free hydraulic jump on adverse stilling basins from a theoretical point of view.

Predicting of Hydraulic Jump Characteristics of Sudden Expanding Stilling Basins Using Evolutionary Algorithm [PDF]
پژوهشهای زیرساختهای عمرانی, 2017 Sudden expanding stilling basins are one of the energy dissipaters which can dissipate most of the kinetic energy of the flow through hydraulic jump.

Modeling Length of Hydraulic Jump on Sloping Rough Bed using Gene Expression Programming [PDF]
Journal of Artificial Intelligence and Data Mining, 2020 Generally, length of hydraulic jump is one the most important parameters to design stilling basin. In this study, the length of hydraulic jump on sloping rough beds was predicted using Gene Expression Programming (GEP) for the first time. The Monte Carlo

The hydraulic bump: The surface signature of a plunging jet [PDF]
, 2013 When a falling jet of fluid strikes a horizontal fluid layer, a hydraulic jump arises downstream of the point of impact provided a critical flow rate is exceeded.

SPH Simulation of Hydraulic Jump on Corrugated Riverbeds
Applied Sciences, 2019 This paper presents a numerical study of the hydraulic jump on corrugated riverbed using the Smoothed Particle Hydrodynamics (SPH) method. By simulating an experimental benchmark example, the SPH model is demonstrated to predict the wave profile ...

Hydraulic flow through a channel contraction: multiple steady states [PDF]
, 2007 We have investigated shallow water flows through a channel with a contraction by experimental and theoretical means. The horizontal channel consists of a sluice gate and an upstream channel of constant width $b_0$ ending in a linear contraction of ...

Effect of Gate Opening Height on the Hydraulic Jump Characteristics in an Open Channel [PDF]
Journal of Applied Fluid MechanicsHydraulic jump is often used to dissipate energy of flow in open channels. Despite extensive study on hydraulic jump, effects of tail gate operation on hydraulic jump remains underexplored in the standard literature.
