Horizontal submerged jet in a stratified fluid

Fluid Dynamics, 1993
The problem of jet flow excited in a viscous density-stratified fluid by a point source of momentum acting horizontally is considered. Simplified asymptotic equations are obtained in the boundary layer approximation. It is shown that the vertical velocity component is small and the motion in the jet has a layered structure.

Cavitating vortex generation by a submerged jet

Journal of Experimental and Theoretical Physics, 2006
The surface geometry of a cavitating vortex is determined in the limit of inviscid incompressible flow. The limit surface is an ovaloid of revolution with an axis ratio of 5: 3. It is shown that a cavitating vortex ring cannot develop if the cavitation number is lower than a certain critical value.

Study of a submerged real-gas jet

Fluid Dynamics, 1966
Results are presented of an experimental study of an axisymmetric liquid nitrogen jet propagating at supercritical pressure (real gas) in a medium of gaseous nitrogen, and a comparison is given of the experimental data and results of theoretical calculations.

Diffusion of Sediment in a Submerged Jet

Journal of the Hydraulics Division, 1966
The relationship between the ratio of the eddy diffusivity for sediment to the eddy diffusivity for momentum and the particle Reynolds number was obtained from the measured velocity and sediment-concentration distributions in a vertical, axi-symmetric, sediment-laden submerged jet directed downward into stationary water. The results have been explained

Submerged Buoyant Jets in Quiscent Fluids

Journal of the Hydraulics Division, 1975
An integral-type analysis is developed for submerged buoyant jets discharged horizontally into quiescent homogeneous fluids. Equations for conservation of volume flux, buoyancy flux, and kinematic conditions are combined with three self-similarity assumptions and one entrainment assumption.

Vortex Containment of Submerged Jet Discharge

Journal of the Hydraulics Division, 1973
The results of an experimental investigation of the discharge of submerged slot jet near a free surface are presented. These results are compared to an analysis which is developed to predict the jet trajectory, velocity profile, and temperature profile. The effects of jet submergence, velocity, and buoyancy are studied.

Axisymmetric Shallow Submerged Turbulent Jets

Journal of the Hydraulics Division, 1973
The modification of a jet flow pattern by a nearby free surface has previously received scant attention. An approximate mathematical model, employing an image jet and utilizing approximations to the P-function is developed to model momentum flux distributions downstream from a shallow submerged axisymmetric turbulent jet with a small initial ...

Surface Disturbance from Submerged Jet

Journal of the Hydraulics Division, 1971
A submerged vertical jet of water impinging on a free surface produces a disturbance at the still water level. The disturbance height and other characteristics of the surface profile depend upon the momentum of the jet, the diameter and depth of submergence of the nozzle from which the jet originates, and the physical properties of the fluids which are

Optimizing submerged jet flocculator performance

Journal AWWA, 1996
Particle removal experiments were conducted to uncover operational parameters leading to optimum performance.A 0.126‐L/s (2‐gpm) pilot plant was constructed to evaluate and optimize a novel water‐jet mixing system for flocculation of suspended particles in water. The jet flocculator pilot plant consisted of a long vertical circular column with influent
