Description

A stable plasma within cavitation bubble created in a liquid can be achieved by applying microwave and ultrasonic irradiation simultaneously. We refer to the latter plasma using ultrasonic vibration as sono-plasma. We propose that plasma in a liquid be applied as a new technique to replace the gas-phase. To control the plasma for practical application, it is important to clarify the behavior of bubbles in liquid. The behavior of a single air bubble in water, n-dodecane and benzene with ultrasound was visualized by use of stroboscope, and calculated by numerical simulation. Single bubble sonoluminescence was observed in the case of using water. However the luminescence phenomenon was not observed in liquid hydrocarbon. When the bubble size is minimum, the deformation of the spherical bubble occured in liquid hydrocarbon. Ultrasonic wave had to be irradiated with much lower amplitude of sound pressure than that in water to hold the bubble, which moved and became unstable with increased of sound pressure. The numerical analysis results are compared with that of the observation data to check the reliability of the analysis.
