Outline of Final Research Achievements |
Collapse of cavitation bubble clouds enhances the mechanical effects of cavitation on therapeutic ultrasound treatments. A software application was developed to clarify the spatial distribution as well as nonlinear behavior of cavitation bubble clouds in a focused ultrasound field. As the results, the effects of the heat and mass transfer through the bubble interface and the translation motion of bubbles on the distribution of the cavitation bubble cloud were clarified by the present numerical simulation. In addition, irradiation parameters of ultrasound for the safe and efficient cavitation-enhanced focused ultrasound treatment werer studied.
