Experimental investigation on submerged water jet wrapped in an annular gas jet
Physics of Fluids, 2023To reduce the energy dissipation of the submerged water jet, a series of experiments of the submerged water jet wrapped in an annular gas jet are performed under different gas ventilation rates, annular sizes, water jet nozzle diameters, and water jet velocities in a transparent water tank.

Cavitation in Submerged Water Jet at High Jet Pressure
Volume 2: Fora, 2015Recent industrial applications have unfolded a promising prospect for submerged water jet. Apart from widely acknowledged water jet properties, submerged water jet is characterized by the formation and complex evolution of cavitation bubbles. These bubbles not just alter the flow behavior of submerged water jet but also pose a profound effect upon ...

Round gas jets submerged in water
International Journal of Multiphase Flow, 2013Abstract 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 ...

Reaction thrust of submerged water jets
Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2007Reaction thrusts of submerged water jets for different cylindrical nozzles are investigated numerically and experimentally. Simplified models of the pressure distribution on the interior walls of high-pressure chambers, the reaction thrust of water jets and the thrust coefficients are all established on the basis of the general characteristics of the ...

Analysis of submerged water jets by visualization method
Journal of Visualization, 2004This paper is concerned with an experimental investigation on plane submerged water jets discharged into quiescent water in an open channel. Flows are visualized by using hydrogen bubbles, solid particles and dye. The results show that the jets attaching to the water surface by the Coanda effect are classified into six types according to their behavior

Momentum and Mass Transfer in a Submerged Water Jet
Journal of Applied Mechanics, 1955Abstract For a round water jet issuing into stationary water, momentum and material diffusion were measured, the latter by means of a sodium chloride tracer technique. It was found that (a) the behavior of the water jet was the same as that found by others for an air jet issuing into air, and hence constants obtained from measurements in

Submerged Abrasive Water Jet Piercing/Drilling: Preliminary Tests
2020In the technological process of cutting by means of an abrasive water jet, the so-called piercing is often used when starting the operation of cutting. As the piercing is a time-important part of the process, it is advantageous to reduce the time by using different piercing strategies.

Spectral peculiarities of turbulent pulsations of submerged water jets
Technical Physics Letters, 2016The spectra of turbulent jet temperature pulsations at 1–40 Hz frequencies have been experimentally studied based on high-speed thermography of the water boundary layer: the region where an impact jet interacts with a surface transparent to IR radiation, as well as the near-wall region where two submerged jets interact in a disc-shaped tee-joint.

Noise from Cavitating Submerged Water Jets
The Journal of the Acoustical Society of America, 1961Frequency spectra of the underwater noise produced by cavitating submerged water jets were determined experimentally for nozzle diameters from 38 to 112 in., efflux velocities from 40 to 175 ft/sec, and ambient pressures up to 2 atm. When cavitation is barely incipient, the rms sound pressure varies with differences in the manner of handling the water ...
