Submerged Radial Hydraulic Jump

Journal of the Hydraulics Division, 1980
A slight flaring of the side walls of the stilling basin can be advantageous in reducing the exit velocities. The hydraulic jump in such a stilling basin is referred to as a radial hydraulic jump. When the sluice gates discharge directly to the stilling basin, a submerged radial hydraulic jump will probably occur. An experimental study produced surface

Submerged hydraulic jump with sediment-laden flow

International Journal of Sediment Research, 2012
Abstract In this experimental study, the effect of suspended sediment concentration on the characteristics of a submerged hydraulic jump in a rectangular channel has been investigated, based on the sediment concentrations of 0.43%-16.15% and jet Froude numbers were in the range of 1.9-5.

Numerical calculation of submerged hydraulic jumps

Journal of Hydraulic Research, 2001
The turbulence characteristics of submerged hydraulic jumps have been investigated numerically by means of the standard k-e turbulence model. The concept of a fractional volume of fluid (VOF) is employed to track the moving free surface. Numerical predictions include surface profiles, hydrodynamic pressures, mean velocities, turbulence intensities and ...

Mean Flow in a Submerged Hydraulic Jump with Baffle Blocks

Journal of Engineering Mechanics - ASCE, 2014
AbstractThe flow in a submerged hydraulic jump with three-dimensional (3D) baffle blocks was experimentally studied. An incoming jet with varying supercritical Froude numbers was deflected with one or two rows of 3D baffle blocks for different downstream water depths.

A numerical study of submerged hydraulic jumps

Journal of Hydraulic Research, 1991
A standard two-dimensional k-e turbulence model is used to predict the mean flow and turbulence characteristics of submerged hydraulic jumps. An offset control volume method is developed to facilitate computation of the variable free surface. The numerical predictions are compared with experimental measurements under three conditions with supercritical

Submerged Hydraulic Jump

Journal of the Hydraulics Division, 1965
This paper presents a study of the submerged hydraulic jump as the case of a plane turbulent wall jet under adverse pressure gradient with backward flow on top. Using the experimental results of the author for the forward flow and those of Liu and Henry for the backward flow, a method has been devised to predict the surface profile, and the fall of the

Submerged Hydraulic Jumps below Abrupt Expansions

Journal of Hydraulic Engineering, 1999
In submerged flows below an expanding outlet, both symmetric and asymmetric flows are observed. The hydraulic conditions required to form a symmetric submerged jump are necessary for design purposes. In this study, the flow conditions are presented for the submerged flows at an abrupt-symmetrical expansion.
