Experimental analysis of hydraulic jump at high froude numbers

open access: yesSādhanā, 2021
The hydraulic jump is a rapid transition state from supercritical to subcritical flow that occurs commonly in rivers, prismatic channels, and downstream of spillways. In this study, the characteristics of the hydraulic jump in a stilling basin downstream

The effect of continuous natural roughness onhydraulic jump characteristics on the stone ramps

open access: yesمجله آب و خاک, 2017
Introduction: The hydraulic jump happens when flow transfers from supercritical regime to subcritical regime. The hydraulic jump on smooth bed is called the classic hydraulic jump.

Predicting hydraulic jump characteristics in a gradually expanding stilling basin with roughness elements by Sugeno Fuzzy Logic

open access: yesJournal of Hydroinformatics, 2022
The hydraulic behavior of a hydraulic jump can be challenging to estimate in order to design gradually expanding stilling basins with roughness elements on the bed.

Surface tension and the origin of the circular hydraulic jump in a thin liquid film [PDF]

open access: yes, 2019
It was recently claimed by Bhagat et al. (J. Fluid Mech. vol. 851 (2018), R5) that the scientific literature on the circular hydraulic jump in a thin liquid film is flawed by improper treatment and severe underestimation of the influence of surface ...

Prediction of the hydraulic jump length on sloping rough beds using meta- heuristic neuro-fuzzy model and differential evolution algorithm [PDF]

open access: yesJournal of Applied Research in Water and Wastewater, 2019
Generally, Hydraulic jumps usually happen at the downstream of hydraulic structures like ogee spillways. In addition, one of the parameters affecting the proper design of stilling basin is calculation of the hydraulic jump length. In this study, a hybrid

Modelling rollers for shallow water flows [PDF]

open access: yes, 2013
Hydraulic jumps, roll waves or bores in open channel flows are often treated as singularities by hydraulicians while slowly varying shallow water flows are described by continuous solutions of the Saint-Venant equations. Richard & Gavrilyuk (J.

Current knowledge in hydraulic jumps and related phenomena: A survey of experimental results [PDF]

open access: yes, 2009
The hydraulic jump is the sudden transition from a high-velocity open channel flow regime to a subcritical flow motion. The flow properties may be solved using continuity and momentum considerations.

Numerical Investigation of Hydraulic Jump Length and position in Ogee Chute [PDF]

open access: yesمهندسی منابع آب, 2018
One of the most effective strategies for energy dissipation of hydraulic structures is hydraulic jump .The position of hydraulic jump play an important role in design of stilling basin.

The flow field downstream of a hydraulic jump [PDF]

open access: yes, 1995
A control-volume analysis of a hydraulic jump is used to obtain the mean vorticity downstream of the jump as a function of the Froude number. To do this it is necessary to include the conservation of angular momentum.

Effect of channel slope and roughness on hydraulic jump in open channel flow

open access: yes, 2021
An experimental study is conducted on hydraulic jump characteristics for understanding the impact of slope in an open channel flume. Hydraulic jump on different channel characteristics (horizontal smooth & rough and sloping smooth & rough) were analysed.
