| Outline of Final Research Achievements |
In this study, an experiment and numerical simulation on interaction of underwater shock wave at the interface of materials with different acoustic impedance was performed, for an establishment of the fundamental research base for the development to the shock wave medical and biomedical application related to human tissue damage by shock wave interacting human body, and the shock wave bioengineering application about a shock wave sterilization technology.
Shock wave interaction phenomena with the interface impedance was visualized by the shadowgraph method and recorded by an ultra-high-speed camera at high spatiotemporal resolution. The shock wave pressure history near the interface was measured simultaneously by a pressure sensor with high spatiotemporal resolution. The process of shock wave interaction with the interface was numerically simulated. The experimental and numerical results obtained is useful for understanding shock wave interaction phenomena with the interface.
