Bubble bursting acoustic
WebMar 16, 2024 · The effect of standing wave components on the generation of cavitation by a heating burst was not considered because the acoustic intensity of a heating burst was much less than that of a trigger pulse. As a result, the trigger HIFU sequence was similar to that used for the bubble-enhanced heating with nanoparticles . In the trigger HIFU ... WebIn our previous computational study of the dynamics of spherical bubble clouds excited by burst waves, it was shown that the amplitude of the far-field acoustic waves scattered by the cloud and the kinetic energy of liquid induced by the bubble dynamics are strongly correlated (Maeda and Colonius, 2024a). This motivates us in this study to ...
