“…One of the most researched application of GA is the dry reforming of methane. Dry reforming of methane [27,28] is a promising process which converts greenhouse gases CH4 and CO2, into syngas -a mixutre of H2 & CO. With GAD, upto 40% conversion of methane has been reported, achieving the energy efficiency target of 60%. In terms of energy cost, it is in the range of 1-3 eV/molecule of CH4 compared to 20-120eV/molecule of CH4 for other plasma sources such as dielectric barrier discharges which has energy efficiency lesser than the target 60% [8].…”

Gliding arc discharge (GAD) reactors are known for high energy efficiency and good chemical selectivity compared to non-thermal plasmas such as glow discharge, corona and dielectric barrier discharge. Reported literature identified that planar diverging GAD have non-uniform gas treatment (e.g. only 20% of gas processed by plasma depending on electrode configuration). Further requirement of minimum limit gas velocity to drag the arc results in lower gas residence time. This paper attempts to investigate the GAD performance and preliminary studies to overcome some of the identified drawbacks, by using only fluid mechanics without magnetic field (rotating gliding arc (RGA)) inside the plasma reactor developed in various research laboratories. This article discusses the applications of GAD and also focuses on bringing out the performance and comparing with the results from the existing non-magnetic rotating gliding arc reactors. The paper also summarizes results from literature in such reactor designs.

Plasma catalysis, the combination of non‐thermal plasma and catalyst, is a promising approach for optimizing chemical conversions as the removal of gas trace components. The various technological opportunities for the generation of atmospheric non‐thermal plasma combined with the variety of usable catalysts result in a huge amount of different experimental approaches. The aim of the presented review is to give an overview of plasma catalytic reactor designs currently discussed in literature as well as to point out technological differences and potential for up‐scaling.

“…The Stark broadening for the FWHM was described by a semiempirical expression proposed by Griem [27] (6) where N e is the electron density, α i is the parameter characterizing the quasi-static ion broadening, T e is the electron temperature, and ω e is the half width at half maximum due to collisions with electrons [29].…”

Next, the Stark broadening ω S and electron density N e were estimated according to (6) and (8), respectively. We obtained a set of plots for ω L (nm/10 16 Tables I and II. In Fig.…”

The spectroscopic characteristics of rotating gliding arc (RGA) discharge, codriven by a magnetic field and tangential gas flow, have been investigated by optical emission spectroscopy. In argon gas, the electron density of the atmospheric RGA plasma was measured, while the vibrotatinoal temperatures were measured in nitrogen discharge. By simulating the spectral line profile determined by the joint effects of Lorentzian (Stark, van der Waals, and natural) and Gaussian (Doppler and instrumental) broadening, the electron density fluctuated in the range of 1.32×10 15 -4.56×10 15 cm −3 and 4.06×10 15 -5.74×10 15 cm −3 within the variation of argon flow rate and applied voltage, respectively. The rotational temperature in N 2 discharge was obtained by comparing the modeled optical emission spectrum with the experimental measurements. The vibrational temperature was derived from a Boltzmann plot by analyzing the spectral bands of the second positive system of N 2 (C 3 u → B 3 g ). The vibrational and rotational temperatures varied in the range of 0.1-0.13 eV and 0.42-0.44 eV, respectively, under the same operating condition, indicating that the RGA discharge is a nonequilibrium plasma. By analyzing the fundamental spectroscopic parameters of the discharge, a comprehensive understanding of RGA plasma was achieved, facilitating its application in practical industry processes.Index Terms-Electron density, plasma, rotating gliding arc (RGA), rotational temperature, vibrational temperature.
