Paper Abstract

In this work, a special designed optical system is used to measure the characteristic of square super-lattice pattern in DBD system. A dielectric barrier discharge system with two liquid electrodes is used, which has a lot of advantages and convenience to the experiment. A square super-lattice pattern is observed in the system at appropriate experimental parameters. The patterns follow as random filaments, square pattern, quasi-super-lattice pattern, square super-lattice pattern, stripe pattern and hexagonal pattern when the applied voltage increases. The influence of the gas pressure p, the gas gap width d, and the pd value (the product of gas pressure p and the gas gap width d) on the square super-lattice pattern are investigated. There are some changes of the pattern scenario when the experimental parameters changes. It is found that the voltage of the square super-lattice pattern increases slightly as d increases. In addition, it is found that the voltage of the square super-lattice pattern decreases as the gas pressure decreases. The square super-lattice pattern can be observed stable and regular at atmosphere pressure when 1.36mm < d < 2.2mm, and the gas pressure is reduced less than atmosphere pressure to obtain the square super-lattice pattern if d >2.2mm.
