| Research Abstract |
This study focused on controllability of argon atmospheric pressure plasma jet(APPJ) by acoustic excitation, and on surface modification. Especially,(1) acoustic excited jet behavior,(2) interaction of ambient fluid and plasma jet,(3) active controlled effect on surface modification were investigated. As a result, following conclusions can be drawn,(1) Acoustic excitation pattern, amplitude and frequency significantly affect on argon APPJ behavior.(2) Argon APPJ behavior is dominated by ambient fluid motion. This fact was confirmed by simultaneous visualization of ambient fluid and argon APPJ.(3) Acoustic excitation is effective to enlarge the area of surface modification.
