Summary: Using gliding arc plasma combined with a swirl burner enhances the combustion performance of ammonia. Optical emission spectroscopy (OES) reveals that with the increase of equivalence ratio, electron density decreases while gas rotational temperature increases. The addition of NH3 significantly reduces NO emission and strengthens the combustion of NH3.

Summary: This study compared the effects of nonthermal plasma treatment on quinine water solutions using two different configurations, and investigated the impact of adding different electrolytes and modifying initial pH on plasma discharge. The results showed that the gliding arc discharge achieved a slightly higher quinine decomposition rate, and that the stability of quinine solutions was influenced by the post-preparation time.

Summary: Through analyzing the spatio-temporal evolution of GAD, a new mechanism governing arc evolution in 3D GAD was revealed. Different from traditional GAD, the PE arc continuously glides while the GE arc jumps, shedding the caudal part and generating a new arc tail simultaneously.

Summary: Dry reforming (DR) and the coupling of DR with partial oxidation reforming (POR) of n-heptane were investigated in a gliding arc discharge (GAD) plasma reactor. The effects of input power, oxygen to carbon ratio, and residence time on the DR process were evaluated, with the highest CO2 conversion rate reaching 42.6%. Optical emission spectra of n-heptane DR and DR coupled with POR were analyzed to detect different reactive species.

Summary: A gliding arc discharge was used to ignite an ethylene-fueled scramjet combustor with an inflow speed of Ma = 2.92. The ignition process can be classified into direct ignition mode and re-ignition mode, with re-ignition mode being more likely in a local fuel-lean environment, exhibiting longer flame propagation time and a smaller flame kernel.

Summary: This paper analyses the collaboration between a GlidArc-type plasma reactor and four dedicated power supplies. Each power supply has a different design solution. Plasma generation by electrical discharge requires careful analysis of power supply design and operating characteristics. The results show that different power supply parameters lead to different plasma reactor performance characteristics. An optimally designed power supply should combine the solutions contained in each of the power supplies tested.

Summary: The epoxy polymer surface modification using air plasma treatment in a Gliding Arc (GA) plasma reactor and a pulsed Dielectric Barrier Discharge (DBD) was studied. The hydrophilicity of the epoxy material was significantly improved by both plasma sources, and the treated surfaces showed enhanced surface oxidation and nano-roughness formation.

Summary: In this study, a gliding arc plasma actuator was designed based on a typical evaporation flameholder to improve the combustion performance of a ramjet under low temperature and pressure. The discharge characteristics and activating effect of single-channel and three-channel gliding arc plasma under different carrier gas flow rates were studied. The results show that three-channel gliding arc discharge has higher discharge power and energy injection rate, effectively widening the ignition boundary and improving the combustion efficiency of the ramjet combustion.

Summary: In recent years, many countries have installed and distributed photovoltaic power generation equipment in remote rural areas, aiming to promote the use of clean energy in rural areas. However, the solar energy that is not used in time needs to be discarded, resulting in a large amount of wasted energy. This study designed a photovoltaic-driven plasma reactor for nitrogen fixation in agriculture, which can effectively use the upcoming waste of solar energy. The experimental results show that the air flow rate has an effect on the discharge mode and yield of nitrogen fixation.
