Toward jet injection by continuous-wave laser cavitation [PDF]

Journal of Biomedical Optics, 2017
This is a study motivated by the need to develop a needle-free device for eliminating major global healthcare problems caused by needles. The generation of liquid jets by means of a continuous-wave laser, focused into a light absorbing solution, was studied with the aim of developing a portable and affordable jet injector.

Scaling study of cavitation pitting from cavitating jets and ultrasonic horns [PDF]

Wear, 2012
Cavitation erosion prediction and characterization of cavitation field strength are of interest to industries suffering from cavitation erosion detrimental effects. One means to evaluate cavitation fields and materials is to examine pitting rates during the incubation period, where the test sample undergoes localized permanent deformations shaped as ...

Useful Correlations for Cavitating Water Jet.

THE REVIEW OF HIGH PRESSURE SCIENCE AND TECHNOLOGY, 1998
In order to use a submerged water jet accompanied with cavitation for practical applications, a cavitating jet was investigated experimentally. The static pressure on the impinging surface was measured to make clear the structure of the cavitating jet. The erosion tests were also carried out to measure the cavitation intensity.

Destruction of Plankton using Cavitating Jet

Journal of Fluid Science and Technology, 2008
This paper presents the experimental result of the destruction of plankton using a cavitating jet generated by a two-dimensional nozzle. The destruction rate of plankton increased with the jet velocity and it reached almost 100% when the nozzle velocity was more than 30 m/s.
