Abstract
When cavitaiton bubbles collapse violently, local high-temperature high-presure pots are generated, which can be used for various chemical reactions, I.e.,conochemistry. It is necessary to control a sound field in order to generate these spots efficiently. We report two exprimental studies: (1) Observation of a single bubble dynamics in ultrasonic field using a stroboscope and light scattering techinique. (2) Amplitude and frequency dependence of the reaction rate of a model chamical reaction with multu bubble conditons.
