Observations of Shock Waves in Cloud Cavitation [PDF]

open access: yes, 1998
This paper describes an investigation of the dynamics and acoustics of cloud cavitation, the structures which are often formed by the periodic breakup and collapse of a sheet or vortex cavity.

Cavitation Observations in a Jet-Flow Gate-Valve

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1984
As a step for clarification of the mechanism of cavitation erosion as well as noises at a jet-flow gate-valve, the cavitation-aspects and the associated sound-pressures were simultaneously observed systematically by means of high-speed-photography and sensitive pressure-detection through a hydrophone, in a 1/10-scale model-valve for various openings ...

The Evolution of Cavitation Events with Speed and Scale of the Flow [PDF]

open access: yes, 1999
This paper focuses on the different forms that individual cavitating events may take when the cavitation number is below the inception value (but not so low as to produce only attached cavities) and individual nuclei trigger individual cavitation events.

The inertial properties of pulsing interflow area of counterflow hydrodynamic radiator

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2015
The jet hydrodynamic radiators (HDR) are the devices where part of kinetic energy of flooded jet is transformed to pulsations of internal interflow area and flow shell fluctuations.

Numerical and Experimental Studies of Cavitation Behavior in Water-Jet Cavitation Peening Processing

open access: yesShock and Vibration, 2013
Water-jet cavitation peening (WCP) is a new technology for the surface modification of metallic materials. The cavitation behavior in this process involves complex and changeable physics phenomena, such as high speed, high pressure, multiple phases ...

Bubbly cloud dynamics and cavitation [PDF]

open access: yes, 2007
In many cavitating liquid flows, when the number and concentration of the bubbles exceeds some critical level, the flow becomes unsteady and large clouds of cavitating bubbles are periodically formed and then collapse when convected into regions of ...
