Cavitation of a Water Jet in Water

, 2012
Cavitation is a phenomenon that occurs in liquids when the pressure drops below the vapor pressure of the liquid. Previous research has verified that cavitation bubble collapse is a dynamic and destructive process.

Numerical Simulation of Cavitating Water Jet by a Compressible Mixture Flow Method

Journal of Fluid Science and Technology, 2011
Concerned on the numerical simulation of high-speed water jet accompanied with intensive cavitation, a practical compressible mixture flow method is developed by coupling a simplified estimation of bubble cavitation and a flexible compressible flow ...

The monitoring of cavitation in centrifugal pumps based on the analysis of vibro-acoustic measurements [PDF]

Cavitation in centrifugal pumps causes damages to pump components and produces high levels of vibration and noise, which not only reduces pump performance but also consumes additional energy.

Numerical Simulation on Structural Optimization of Helmholtz Cavitation Jet Nozzle

Shiyou jixie
The structural size of Helmholtz cavitation jet nozzle is large and not suitable for blockage removal by cavitation jet flushing. Moreover, there is a lack of evaluation on the jet pulse property in related studies.

Effect of Cavitation in Cylindrical and Two-dimensional Nozzles on Liquid Jet Formation [PDF]

, 2011
Cavitation in various nozzles of different geometries and dimensions, i.e., two-dimensional (2D) and cylindrical nozzles, and liquid jets discharged from the nozzles are visualized using a digital camera, and the index for estimating cavitation in a ...

Synthetic jet generation by high-frequency cavitation

, 2017
Cavitation bubbles are nucleated at a high repetition rate in water by delivering a pulsed laser through a fibre optic. Continuous high-frequency cavitation drives a stream away from the fibre tip.

Development and Test of Cavitation Jet Hydro-Oscillator

Shiyou jixie
Scaling in wellbore may lead to sticking and thus reduced oil production. In order to solve this problem,based on the principle of generation of shearing cavitation by drowned jet,a cavitation jet hydro-oscillator was designed,which was used together ...
