Ejecta-Modulated Bubble Dynamics Play a Dominant Role in Stone Retropulsion. [PDF]

open access: yesAdv Sci (Weinh)
Stone motion during laser ablation is shown to result primarily from asymmetric cavitation bubble collapse, not from ejecta recoil. This challenges long‐standing assumptions and highlights the dominant role of bubble dynamics in laser–material interactions.

Dynamics of a Cavitating Propeller in a Water Tunnel [PDF]

open access: yesJournal of Fluids Engineering, 2003
This study investigates the unsteady dynamics and inherent instabilities of a cavitating propeller operating in a water tunnel. First, the steady characteristics of the cavitating propeller such as the thrust coefficient are obtained by applying continuity and momentum equations to a simple one-dimensional flow tube model.

Cavitation tunnel characterized by stable cavitation-nuclei-distributions.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1988
In order to establish the necessary condition for such cavitation experiments in an open type cavitation tunnel, the cavitation nuclei distributions were carefully measured in the test water sampled from a fixed point in the stilling reservoir for a typical flow quantity, by means of a Coulter counter.

Natural nuclei population dynamics in cavitation tunnels [PDF]

open access: yesExperiments in Fluids, 2020
Nuclei, or microbubble, populations control the inception and dynamics of cavitation. It is, therefore, important to quantify distributions in cavitation test facilities to rigorously model nucleation dynamics. Measurements of natural nuclei population dynamics were made in two test facilities in Australia and Japan via mechanical activation using a ...
