Numerical simulation of free and submerged hydraulic jump over trapezoidal and triangular macroroughness [PDF]
Heliyon, 2023 Hydraulic jump is a phenomenon that occurs in open channel flow and has wide utility in hydraulic engineering. The present study considered macroroughness features in the bed to improve the characteristics of free and submerged hydraulic jumps. For that,

Shock and Vibration, 2022 Water flow often releases excess energy after passing through gates and spillways. This energy should be reduced to avoid the destruction of downstream structures. The hydraulic jump, a natural phenomenon, inevitably reduces incoming flow energy.

Hydraulic Jump in One-dimensional Flow [PDF]
The European Physical Journal B - Condensed Matter and Complex Systems, 2005 In the presence of viscosity the hydraulic jump in one dimension is seen to be a first-order transition. A scaling relation for the position of the jump has been determined by applying an averaging technique on the stationary hydrodynamic equations. This

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.

Water, 2022 Since the hydraulic jump off a tidal bore in the Kampar Estuary has never been well-described, real-time measurements of hydraulic jump properties are crucial to understanding the tidal bore characteristics.

The transient spread of a circular liquid jet and hydraulic jump formation
Journal of Fluid Mechanics, 2022 Abstract The transient flow of a circular liquid jet impinging on a horizontal disk, and the hydraulic jump formation, are examined theoretically and numerically. The interplay between inertia and gravity is particularly emphasised.

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 ...
