A numerical model for cloud cavitation based on bubble cluster

open access: yesTheoretical and Applied Mechanics Letters, 2017
The cavitation cloud of different internal structures results in different collapse pressures owing to the interaction among bubbles. The internal structure of cloud cavitation is required to accurately predict collapse pressure.

Cavitation induced starvation for piston-ring/liner tribological conjunction. [PDF]

open access: yes, 2011
The study investigates the mechanism of ring-liner lubrication in the vicinity of the top and bottom dead centres of an internal combustion engine. Predicting lubricant transient behaviour is critical when the inlet reversal leads to thin films and ...

Experimental study on damage mechanism of blood vessel by cavitation bubbles

open access: yesUltrasonics Sonochemistry, 2023
Ultrasound-induced cavitation in blood vessels is a common scenario in medical procedures. This paper focuses on understanding the mechanism of microscopic damage to vessel walls caused by the evolution of cavitation bubbles within the vessels.

Numerical modelling of acoustic cavitation threshold in water with non-condensable bubble nuclei

open access: yesUltrasonics Sonochemistry, 2022
Numerical modelling of acoustic cavitation threshold in water is presented taking into account non-condensable bubble nuclei, which are composed of water vapor and non-condensable air.

Hydrodynamics, acoustics and scaling of traveling bubble cavitation [PDF]

open access: yes, 1994
Recent observations of the geometries of growing and collapsing bubbles over axisymmetric headforms have revealed the complexity of the "microfluidmechanics" associated with these flows (Hamilton et al., 1982, Briancon Marjollet and Franc, 1990, Ceccio ...

Numerical simulation of three-dimensional cavitation bubble oscillations by boundary element method [PDF]

open access: yes, 2009
This work is devoted to a numerical investigation of threedimensional cavitation bubble. Bubble oscillations in ambient unbounded fluid are investigated numerically. The fluid is assumed inviscid, incompressible and unbounded and the flow is irrotational.

Enhancement of oscillation amplitude of cavitation bubble due to acoustic wake effect in multibubble environment

open access: yesUltrasonics Sonochemistry, 2021
Acoustic cavitation occurs in ultrasonic treatment causing various phenomena such as chemical synthesis, chemical decomposition, and emulsification. Nonlinear oscillations of cavitation bubbles are assumed to be responsible for these phenomena, and the ...

The study of surface processes under electrochemical control in the presence of inertial cavitation [PDF]

open access: yes, 2005
In some circumstances, the erosive effects of inertial (transient) cavitation have been usefully employed in the acceleration of chemical processes that are dependent on surface reactions.

Dynamic behavior of the cavitation bubbles collapsing between a rigid wall and an elastic wall

open access: yesAIP Advances, 2021
There are various bubble cavitation phenomena in daily production and life, and near-wall cavitation is the most common one. This paper studies the bubble cavitation dynamics between a rigid wall and an elastic wall, and by changing the distance between ...
