Numerical Study of the Pulsation Process of Spark Bubbles under Three Boundary Conditions
In this study, a compressible three-phase homogeneous model was established using ABAQUS/Explicit. These models can numerically simulate the pulsation process of cavitation bubbles in the free field, near the flat plate target, and near the curved ...

The collapse of single bubbles and approximation of the far-field acoustic emissions for cavitation induced by shock wave lithotripsy [PDF]
Recent clinical trials have shown the efficacy of a passive acoustic device used during shock wave lithotripsy (SWL) treatment. The device uses the far-field acoustic emissions resulting from the interaction of the therapeutic shock waves with the tissue

Effects of Polydispersity in Bubbly Flows [PDF]
This thesis concerns the dynamics of bubbly flows with a distribution of equilibrium bubble sizes. The main goal is to formulate the physical and numerical models of continuum bubbly flows that enable us to efficiently compute the average mixture ...

Modelling of the cavitation bubbles dynamics [PDF]
The goal of this study is to apply a numerical model for cavitation bubble dynamics that is based on the existing Rayleigh-Plesset equation (RPE). Physical background and derivation of the RPE are given, as well as the basic phenomena associated with ...

Laser Induced Breakdown and Bubble Cavitation [PDF]
This work presents the results of an experimental investigation of laser induced cavitation. We find that the breakdown plasma can be randomly split in different branches depending on the laser energy and on the focusing angle.

Research on the Cavitation Flow Characteristics and Transport Mechanism of Rotating Cascades [PDF]
In this study, a numerical simulation combining the Detached Eddy Simulation (DES) model with the Zwart Gerber Belamari (Z-G-B) cavitation model is used, along with a visualization experiment, to analyze cavitation flow within a rotating cascade.

Cavitation damage is a micro, high-speed, multi-phase complex phenomenon caused by the near-wall bubble group collapse. The current numerical simulation method of cavitation mainly focuses on the collapse impact of a single cavitation bubble.

Radial oscillation and translational motion of a gas bubble in a micro-cavity
According to classical nucleation theory, a gas nucleus can grow into a cavitation bubble when the ambient pressure is negative. Here, the growth process of a gas nucleus in a micro-cavity was simplified to two “events”, and the full confinement effect ...
