In Situ Analysis of Discharge Sound and I-V Characteristic on Gliding Arc Discharge for Nano Particle Preparation

Abstract Electrical and sound characteristics of gliding arc have been taken to analyze and discuss the discharge mechanism, which is very complex due to the plasma non-uniformity in space and time. This work focuses on the relationship between discharge current and sound during gliding arc discharge. Measurement and analysis of waveforms of applied voltage, discharge current and discharge sound were carried out. New technique of optical wave microphone was introduced to observe generation of compressional wave after one pulsed discharge in air.
