Energy Focusing in High-Amplitude Sound Fields

摘要

The objectives for this project were to better understand sonoluminescence conditions, expand the parameter space for sonoluminescence, enhance the cavitation collapse sequence, and implement enhanced-cavitation generators to search for tritium production. Modeling studies were performed to determine additional paths to unknown stable parameter spaces. Experiments were performed to determine methods and mechanisms for enhancing cavitation collapse. PZT array and spark-gap lithotripter-based systems were designed, built and tested. The spark-gap lithotriper worked as planned, but the count rate was too slow for practical applications. The PZT array system worked, but final testing was not completed because funding was exhausted.
