摘要

The three-dimensional boundary element method was improved to simulate the collapse and rebound of a bubble near a compliant wall. The compliant wall was modeled with mass-spring systems. First, the simulation was performed for the growth and collapse of a single bubble near a compliant boundary. A typical single bubble behavior near the boundary such as neutral bubble collapse was simulated successfully with the present method. The present method was also applied to the growth and collapse of multiple bubbles near a compliant boundary. The results show that the bubble behavior was much dependent on both the bubble-bubble and bubble-wall interactions. We have succeeded in simulating the formation of three-dimensional liquid-jets. Wavy surface was formed on the compliant boundary due to the collapse of interacting two bubbles. Also, the thermal effects of the internal gas were evaluated using the effective polytropic index.
