Abstract :
A nonequilibrium plasma jet array is reported in this paper. The gas temperature of the plasma array is at room temperature. High-speed photographs show that the propagation speed of each plasma plume is not the same. At the beginning, the propagation speed of the plasma plumes on both edges is higher than that in the middle of the plasma array. The simulation results indicate that this is due to the electric-field distribution of the plasma array. After 125 ns, the behavior of the plasma plumes looks like glow discharges.
