EFFECT OF INTENSE MECHANICAL VIBRATION OF ULTRASONIC FREQUENCY ON THERMAL UNSTABLE LOW-TEMPERATURE PLASMA

摘要

In this study, plasma discharge in liquids in the intense ultrasonic field above the cavitation threshold has been proven to be of great interest for initiation of various physical and chemical processes. The feature of arc discharge in liquid media is the localization of plasma region near the electrodes and the "falling" form of volt-ampere characteristics. In the region of intense cavitation, the fraction of gas-vapor component in the liquid exists, therefore it can be assumed that the electric breakdown in the cavitation region should become easier, which can result in initiation of various forms of discharges.
