A cavitation cloud forms when a high-pressure water jet is submerged in a tank of quiescent water. The water jet is formed as high-pressure nitrogen forces a fixed-volume column of water through a nozzle. The diameter and exit velocity of the water jet affect the behavior and geometry of the resulting cavitation.

Mapping cavitation impact field in a submerged cavitating jet
Wear, 2018Abstract A full assessment of the cavitation erosion potential of a cavitating jet necessitates the determination of the cavitation impact field. However, a detailed description of the impact intensity and spatial distribution of the large numbers of cavitation impacts has not been fully established.

An Experimental Investigation of Cavitating Jet Dynamic Power and Cavitation Intensity
Volume 7: Fluid Flow, Heat Transfer and Thermal Systems, Parts A and B, 2010The principal focus of this investigation were the effect of hydrodynamic and geometrical parameters on cavitating jet dynamic power and cavitation intensity under different flow conditions. Jet performance indicators were taken to be the erosion rate of the target surface and the size of the erosion area..

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 ...

Hydraulic Pulsed Cavitating Jet-Assisted Drilling
Petroleum Science and Technology, 2009Abstract How to improve drilling rate in deep wells has been a hot subject. Based on modulating pulse jet and cavitating jet, a new drilling tool is designed which couples advantages of both pulse jet and cavitating jet. When drilling fluid flows through the tool during the drilling process, fluid is modulated to pulse and cavitate.

Cavitating Jet Apparatus for Cavitation Erosion Testing
1979A submerged cavitating jet is used to erode a specimen placed in its path. The erosion depends primarily on the jet velocity, the downstream pressure, and the standoff distance of the specimen. An apparatus for erosion testing based on this principle is described. Results are presented showing the effect of these parameters on erosion.

Jet Impact and Cavitation Damage
Journal of Basic Engineering, 1968On the basis of presently known erosion theories, an analogy is made between jet impact and cavitation erosion, and confirmed by experiments. As a consequence of this analogy, data on jet impact experiments are used to explain some peculiar aspects of cavitation damage.

Sheet Cavitation and Cloud Cavitation, Re-Entrant Jet and Three-Dimensionality
1998The unsteady behaviour of a sheet cavity on a hydrofoil under stationary conditions is important with respect to both noise generation and erosion. Observations of two-dimensional as well as three-dimensional cavities are performed. From the observation it is concluded that the formation of a re-entrant jet is of major importance to explain the ...

Cavitation about a jet in crossflow
Journal of Fluid Mechanics, 2015Cavitation occurrence about a jet in crossflow is investigated experimentally in a variable-pressure water tunnel using still and high-speed photography. The 0.012 m diameter jet is injected on the centreplane of a 0.6 m square test section at jet to freestream velocity ratios ranging from 0.2 to 1.6, corresponding to jet-velocity-based Reynolds ...

Cavitating flow in annular jet pumps
International Journal of Multiphase Flow, 2015Abstract Based on the experimental and numerical methods, the pump performance and inner flow details of annular jet pumps under three area ratios (cross sectional area ratio of throat and nozzle) were studied in the present paper. The cavity clouds forming at the shearing layer, recirculation center and throat inlet were captured via high speed ...
