Effect of corrugated beds on characteristics of submerged hydraulic jump
Ain Shams Engineering Journal, 2014 Hydraulic jump is generally helped in the dissipation of excess kinetic energy downstream of hydraulic structures such as gates, spillways, and weirs. This paper presents a comprehensive review of the available literature on the hydraulic jump properties

Laboratory evaluation of artificial roughness and adverse slope effect in control of hydraulic jump [PDF]
مهندسی منابع آب, 2023 Introduction: Hydraulic jump is created at the end of shoots and many hydraulic structures. The occurrence of a hydraulic jump phenomenon leads to a decrease in the amount of energy in open channels.

Effect of different screen areas on the submerged hydraulic jump characteristics [PDF]
Port Said Engineering Research Journal, 2022 The hydraulic jump is a natural phenomenon occurs in steep waterways and behind the heading up structures. The main benefit of the hydraulic jump is dissipating the excessive kinetic energy. Tools such as sill, baffle blocks… etc.

Effect of different screen widths on the submerged hydraulic jump characteristics [PDF]
The Egyptian International Journal of Engineering Sciences and Technology, 2021 Hydraulic jump used to dissipate excessive kinetic energy in natural water ways since the down of time. Screens fixed in the stilling basin to control the hydraulic jump location, depth and length from four decades ago.

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 ...

Hydraulic Jump in a Rotating Fluid [PDF]
The Physics of Fluids, 1964 A hydraulic jump occurs in a layer of fluid flowing down the inner wall of a rotating cylinder when the downstream conditions are adequate. The theory of these jumps is presented, together with supporting experimental data. The results confirm the similarity between free-surface flows under general rotation (and hence centripetal acceleration) and free-

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.
