Spatio-temporal patterns in dielectric barrier discharge in air/argon at atmospheric pressure
Abstract
A rich variety of patterns including travelling hexagon, travelling square, quasi-crystal, static hexagon and stripe have been studied in a dielectric barrier discharge system. The phase diagram of pattern types as a function of air concentration and the applied voltage is given. The spatio-temporal correlations between discharge filaments in these patterns are measured in a nanosecond time scale by an optical method. It is found that the travelling pattern is an interleaving of two sub-patterns with a temporal sequence inversion in consecutive half-cycles.
