“…During the past decades gliding arc discharges have been widely used in combustion enhancement [5][6][7], gas conversion and decomposition [8][9][10][11], bacterial inactivation [12,13], surface treatment [14,15] and pollution control [16][17][18]. Many of these applications rely on the formation of reactive species that can increase chemical reaction rates [19,20].…”

Abstract:Translational, rotational, vibrational and electron temperatures of a gliding arc discharge in atmospheric pressure air were experimentally investigated using in situ, nonintrusive optical diagnostic techniques. The gliding arc discharge was driven by a 35 kHz alternating current (AC) power source and operated in a glow-type regime. The twodimensional distribution of the translational temperature (T t ) of the gliding arc discharge was determined using planar laser-induced Rayleigh scattering. The rotational and vibrational temperatures were obtained by simulating the experimental spectra. The OH A-X (0, 0) band was used to simulate the rotational temperature (T r ) of the gliding arc discharge whereas the NO A-X (1, 0) and (0, 1) bands were used to determine its vibrational temperature (T v ). The instantaneous reduced electric field strength E/N was obtained by simultaneously measuring the instantaneous length of the plasma column, the discharge voltage and the translational temperature, from which the electron temperature (T e ) of the gliding arc discharge was estimated. The uncertainties of the translational, rotational, vibrational and electron temperatures were analyzed. The relations of these four different temperatures (T e >T v >T r >T t ) suggest a high-degree non-equilibrium state of the gliding arc discharge. Phys. 79(5), 2245-2250 (1996). 3. A.

“…17 Furthermore, the diffusive arc length is up to 25 cm, which is 5-10 cm longer than gliding arc discharges reported previously. 9,14 The power dissipated in the plasma column is about 700 W when the plasma column has a length of 25 cm. Note that the dispersion of measurements in Fig.…”

“…6,7 Gliding arc has been recognized to provide high operating power in non-thermal conditions at atmospheric pressure. [8][9][10][11][12][13][14][15] Nevertheless, the reported gliding arcs generally suffer from limited existing period 16 and volume. 17 In this letter, we report on comprehensive investigations of a sustained diffusive alternating current (AC) gliding arc with large volume and high power.…”

drift motion is in the same direction as the gas flow in plasma jets and gliding arc discharge. [ 22,23 ] Liu et al investigated the effect of parallel magnetic field on plate‐plate DBD; they found that the intensity and uniformity of the discharge were improved simultaneously with the parallel magnetic field. [ 24 ] Ma et al studied the influence of perpendicular magnetic field on the decomposition of VOC using a wire‐to‐cylinder type reactor, the VOC removal efficiency was remarkably improved with the application of the magnetic field.…”

In this study, a magnetic field perpendicular to the electric field is introduced to the gear-cylinder dielectric barrier discharge (DBD) to enhance the plasma density and improve the volatile organic compounds removal performance at atmospheric pressure. Higher discharge intensity, enlarged plasma streamers region, and better toluene removal performance are obtained after introducing a 0.2 T magnetic field
