The Numerical Investigation on Bubble Interaction Dynamics in Hydrodynamic Cavitation

Numerical Investigation of the Effect of Bubble-Bubble Interaction on the Power of Propagated Pressure Waves

The study of bubble dynamics, especially the interaction of bubbles, has drawn considerable attention due to its various applications in engineering and science. Meanwhile, the study of the oscillation effect of a bubble on the emitted pressure wave of another bubble in an acoustic field which has less been investigated. This issue is investigated in the present study using the coupling of Kell...

Cavitation bubble dynamics.

The dynamics of cavitation bubbles on water is investigated for bubbles produced optically and acoustically. Single bubble dynamics is studied with laser produced bubbles and high speed photography with framing rates up to 20.8 million frames per second. Examples for jet formation and shock wave emission are given. Acoustic cavitation is produced in water in the interior of piezoelectric cylind...

An Investigation into the Effects of Viscoelasticity on Cavitation Bubble Dynamics with Applications to Biomedicine

Numerical Investigation of Bubble Cloud Dynamics in Shock Wave Lithotripsy

To provide greater understanding of some of the phenomena in Extracorporeal Shock Wave Lithotripsy (ESWL), we implemented a two-phase continuum model for cavitating flow and applied it to the simulation of bubble cloud dynamics in an electrohydraulic lithotripter. Through the combination of a WENO shock capturing scheme, curvilinear coordinates system and ensemble averaged mixture model, we com...

Acoustic Cavitation and Bubble Dynamics 611

Acoustic cavitation is investigated experimentally and theoretically starting with a single bubble in an acoustic field. The single bubble is trapped in an acoustic resonator and observed by high-speed imaging and acoustic measurements following its transient dynamics to a possible steady state after generation by laser light. Numerical calculations are done to explore the regions of survival f...
