Self-Organized Pattern of DBD Microdischarges due to Streamer Interaction... 

Figure 4-10. Illustration of interaction between the DBD mierodiseharges (quasi-repulsion) related to an eleetrie field distortion eaused by the microdiseharge remnant. Streamer formation (left-hand side) and plasma ehannel (and mierodiseharge remnant) eleetrie field distortion (right-hand side) are due to space eharges. The figure shows the eleetrie field from the mierodiseharge, the applied external eleetrie field, and their superposition. In the presence of a spaee positive eharge, the eleetrie field is increased at the cathode and decreased at the anode.

Monte Carlo Modeling of Interaction of Streamers and Microdischarges... 

The cellular automata (CA) scheme, applied for the streamer and microdischarge interaction modeling, consists of a lattice of cells that can have any dimension and size coupled with... 

Thus, the interaction of streamers in DBD can lead to the formation of an organized structure of microdischarges (similar to Coulomb crystals see Fridman Kennedy, 2004), which plays a significant (sometimes positive, sometimes negative) role in plasma-chemical applications. From this perspective it is important to analyze how highly organized the... 

The avalanche-to-streamer transition in the APG DBD depends on the level of preionization. The Meek criterion (Section 4.1.3) is related to an isolated avalanche, whereas in the case of interrsive pre-ionizatiorr, avalanches are produced close to each other and interact. If two avalanches occm close enough, their transition to streamers can be electrostatically prevented and the discharge remains uniform (A. Fridman et al., 2005). A modified Meek criterion of the avalanche-to-streamer transition can be obtained by considering two simrrltaneously starting avalanches with maximum radius R, separated by the distance L (a is Townsend coefficient, d is distance between electrodes) ... 

At the present time, no satisfactory correlation has been established between streamer propagation and either the electronic properties (mobility, lifetime of electrons or holes) or the optical properties (interaction with radiation, luminescence) of liquids.
