KHz Alternating Current Stable Plasma in Alcohol Aqueous Solution

Abstract

Discharge in liquid has been studied in many forms and water is the mostly used liquid in those researches. In this paper, alcohol aqueous solution is used to form stable discharging. A kilo-Hz alternating current high voltage power source is used to generate plasma under the surface of liquid and the power frequency set is the range of 1~20 kilo-Hz. The voltage-current curve, optical emission spectrum and many other evidences show that the discharging in liquid is intermittent with high optic effect.
