“…According to different electrode configurations, DBDs can be divided into volume discharges, surface discharges and coplanar discharges [3]. Already implemented and in development applications of DBDs include plasma catalysis [4], air pollution control [5][6][7], light source generation [8,9], materials processing for microelectronics and photovoltaic cells [10], medical equipment disinfection [11], plasma-assisted flow control [12][13][14], plasma-assisted ignition and combustion [15][16][17][18], etc.…”

The ﬁne structure of a streamer–to–ﬁlament transition in a single–shot high–voltage nanosecond surface dielectric barrier discharge (nSDBD) in molecular nitrogen at pressure $P = 6$~bar was studied with the help of ICCD microimaging. An intermediate discharge structure, existing for only a few nanoseconds, was observed in the time interval between two discharge modes: streamer discharge, with a typical electron density of $n_e \sim 10^{15}$~cm$^{-3}$, and ﬁlamentary discharge, with $n_e \sim 10^{19}$~cm$^{-3}$. The structure was observed for both polarities of the high–voltage electrode. The structure can be brieﬂy described as a stochastic appearance of thin channels propagating a bit faster than the main ionization front of merged surface streamers, transforming in a few nanoseconds in a bi–directional ionization wave. One wave, which we associate with a feather–like structure in optical emission, propagates further away from the high–voltage electrode, and another, a backward wave of emission, propagates back towards the edge of the high–voltage electrode. When the backward wave of emission almost reaches the high–voltage electrode, the ﬁlament appears. Plasma properties of the observed structure were studied to better understand the nature of a streamer–to–ﬁlament transition. Theoretical analysis suggests that the instability of a ﬂat front of ionization wave (Laplacian instability) triggers the streamer–to–ﬁlament transition, and that a surface stem (a tiny region with enhanced electron density) should be in the origin of the bi-directional ionization wave.

“…Finally, the remains of the reactions are retained in an activated carbon bed, which also reverts the residual ozone to atmospheric oxygen. The economical, long serviceable life of the activated carbon provides a high advantage of this technology (Brandenburg et al, 2011).…”

“…Non-thermal Plasma Non-thermal plasma as dry or wet system is an emerging technology for VOC, SOx and NOx emission control with low power consumption and by-product production [15,16]. The fundamental nature of non-thermal plasma is that the electron temperature is much higher than that of the gas temperature, including molecular vibrational and rotational temperatures.…”

A non-thermal plasma reactor (NTPR) using two 2.45 GHz Microwave (MW) generators for the abatement of Nitrogen Oxides (NOx) and Sulphur (SOx) contained in the exhaust gas of a 200 kW marine diesel engine was built and tested. Numerical analysis based on a non-thermal plasma kinetics model for the abatement of NOx and SOx from marine diesel engine exhaust gas was performed. A generic kinetic model that implements electron collisions and plasma chemistry has been developed for applications involving low temperature (50K-100K) non-thermal plasma. Abatement efficiencies of NOx and SOx were investigated for a range of mean electron energies which directly impact on the rate constants of electron collisions. The simulation was conducted using the expected composition of exhaust gas from a typical two-stroke slow speed marine diesel engine. The simulation results predict that mean electron energy of 0.25eV-3.2eV gives abatement efficiency of 99% for NOx and SOx. The minimum residence time required was found to be 80ns for the mean electron energy was 1eV. Multi-mode cavity was designed using COMSOL multi-physics. The NTPR performance in terms of NOx and SOx removal was experimentally tested using the exhaust from a 2 kW lab scale two stroke diesel engine. The experimental results also show that complete removal of NO is possible with the microwave plasma (yellow in color) generated. However it was found that generating right Microwave plasma is a challenging task and requires further investigation.
