“…Gas phase reaction mechanism is essentially the same as that described in [30]. The gas mixture is atmosphericpressure air at 300 K. The species included in the reaction mechanism are: Secondary electrons emitted from surfaces and their tra jectories are traced by the electron Monte Carlo simulation module (EMCS) [31][32][33]. Fluid module coupled with the EMCS module represent the socalled 'beambulk' model.…”

In this paper, we present the results from the computational study of the two competing mechanisms of precursor electrons production—conventional photoionization and preionization by fast electrons from the cathode. To discriminate between the two mechanisms we simulate a negative streamer evolution under conditions when photoionization is zero/non-zero and/or fast electrons are present/absent. In the absence of all factors producing the precursor electrons the streamer eventually stalls. We show that the effect of fast electrons on streamer evolution is similar to that of the photoionization but it is more stochastic by nature. The domination of one or another of the mechanisms considered depends on the pulse duration and voltage amplitude (other conditions being equal).

“…When the hybrid approach is used, we treat trajectories of secondary electrons emitted from surfaces with the Electron Monte Carlo Simulation Module (EMCS), which is described in ref . EMCS module coupled with the fluid equations is a kind of a “beam‐bulk” model where conventional fluid equations describe the bulk electrons and ions.…”

We report on a computational study of the intersection of plasma filaments in a dielectric barrier discharge with small particulates suspended in air or residing on surfaces. The relative location of the particle with respect to the streamer axis is important on plasma time scale considered in the paper. The particulates residing on the substrate surface are partially enveloped by the sheath formed beneath the filament and the substrate. Ion energies and fluxes incident on the particulate depend on dielectric properties of the underlying substrate materials.

Micro-dielectric barrier discharges (mDBDs) are known for being stable, high-pressure and non-thermal plasma sources. mDBD arrays consist of micro-plasma devices (10-100 µm) in which the radio frequency (rf)-excited electrodes are covered by dielectrics. In certain applications, independent control of individual mDBDs in an array is required for charge extraction to treat dielectric surfaces. When using the mDBDs to produce plumes of charged species, there are potential direct or indirect interactions between the mDBD devices. In this paper, we discuss the characteristics of atmospheric mDBD arrays sustained in N 2 with an O 2 impurity using results from a two-dimensional simulation. The device of interest consists of a sandwich structure using layers of dc and rf biased electrodes to help shape the plume. We found that the adjacency of the mDBDs and the dielectric properties of the materials being treated are important to the interactions between mDBDs in the array. Scaling laws are presented for operating characteristics of these mDBD arrays as a function of material properties, geometry, driving voltage waveform and gas mixture.
