Abstract :
Nowadays, atmospheric pressure plasma jets using a dielectric-barrier discharge with an axial symmetry configuration attract the interest of many researchers. However, the mechanisms responsible for the generation of atmospheric plasma jets still remain unknown. In this paper, using intensified charge-coupled device images, we present the “bulletlike” structures of a plasma jet traveling at supersonic velocities.
