• S054021 Control of Atmospheric Pressure Plasma Jet by Shear Layer Excitation

抄録

This paper described on the controllability of jet shear layer excitation by sound wave to which apply an argon atmospheric-pressure plasma jet. Our previous study showed periodic swing and stretching motions of the plasma jet by the excitation, but the bound condition of the method is still not clear. We, therefore, investigate the limit of the control. A visualization of the plasma jet was conducted by use of a high speed video camera, and we analyzed spatial and temporal motions of the jet via image processing, and then its controllability was estimated. As a result, the asymmetric mode enhances the jet oscillations as increasing with the sound amplitude, but the symmetric mode only affects the jet stretching. The excitation conditions; amplitude and frequency show significant influence on the jet behavior. The detail phenomenon which focused on nature of the working gas and the surround fluid will be presented in the conference.
