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