Round gas jets submerged in water

International Journal of Multiphase Flow, 2013
Abstract Water submerged gas jets are characterized by the interplay of inertia and buoyancy forces and can exhibit diverse behaviors ranging from bubbly plumes to stable jets. In this work, direct measurements of the interfacial behavior of water-submerged gas jets, with Mach numbers ranging from subsonic to supersonic, were performed using high ...

Hydraulic Erosion of Concrete by a Submerged Jet

Journal of Materials Engineering and Performance, 2002
The hydraulic erosion of concrete is often found in civil and marine engineering construction. The present study explores the effects of several erosion parameters on the material loss of a concrete specimen subject to the hydraulic flow produced by a submerged jet. Such an investigation has rarely been reported in the literature. The concrete specimen

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.

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.

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

Flow Characteristics of Submerged Jets

Transactions of the American Society of Mechanical Engineers, 1929
Abstract In this paper, which deals with submerged square-edged and chamfered short tubes or jets, the author shows by dimensional analysis and corroboratory experiment that the coefficient of discharge for geometrically similar jets is a function of the rate of discharge, the fluidity of the liquid, and the jet diameter.

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.

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.
