Characteristics of Optical Emission Spectra and Schlieren Image for Two Atmospheric Pressure Plasma Jets
POSTER
Abstract
Atmospheric pressure plasmas (APPs) produce reactive chemical species without vacuum chambers and pumps [1]. Among the many applications of APP, An atmospheric pressure plasma jet (APPJ) is a popular tool used to generate plasma plumes at a low breakdown voltage with Ar or He gas compared with air discharge [2]. In this study, two APPJ structures were placed in an anti-parallel or a perpendicular direction, and the characteristics were observed using a Schlieren image and a high-speed camera. In addition, the chemical species generated by the APPJ according to the change of voltage and gas flow rate were analyzed using optical emission spectroscopy (OES). The difference in the observed intensity according to the power was shown. The electrical characteristics were presented by calculating the capacitance and power consumption through the Lissajous curve.
