Dynamic behavior of micro-bubbles in ultrasonic field
Details
When cavitation bubbles collapse violently, local high-temperature high-pressure spots are generated, which can be used for various chemical reactions, i.e., sonochemistry. It is necessary to control a sound field in order to generate these spots efficiently. We report two experimental studies: (1) Observation of a single bubble dynamics in ultrasonic field using a stroboscope and light scattering technique. (2) Amplitude and frequency dependence of the reaction rate of a model chemical reaction with multi bubble conditions.
