Gas flow modification by a kHz microsecond atmospheric pressure plasma jet
Résumé
In this work we present Schlieren images of a Plasma Gun discharge fed not only with helium but also for the first time with neon and argon buffers. It is demonstrated that efficient gas flow channelling is observed with operation of the PG with any of the three gases. Such gas flow channelling is also proven to be dependent on voltage polarity and frequency. Analysis of the role of molecular admixtures (N2 or O2) confirms the non-thermal nature of the effect and the potential crucial role of large negative ions.
