Stability and emission characteristics of ammonia/air premixed swirling flames with rotating gliding arc discharge plasma

The Influence of Voltage on Gliding Arc Discharge Characteristics, the Composition of Air Plasma, and the Properties of BG-11 Medium

“…It should be noted that, with the increase in the output voltage of voltage generator from 50 V to 250 V, the arc column becomes longer, and both the voltage and current waveform last longer [20,38]. Similar behaviors of the voltage and current waveforms were obtained for different gliding arc discharges [13,16,20].…”

“…The pd value is enhanced with the increase in the arc length, and at the critical arc length the voltage becomes insufficient to sustain the elongation of the discharge [9]. It should be noted that the duration of the discharge, the voltage, and current values depend on the shape of the electrodes as well as on the flow rate of the gases and the voltage values [13,16,20,38]. However, the shape and period of the waveforms were slightly different even when the output voltage was kept constant (Figure 2b).…”

“…The gliding arc discharge (GAD) plasma setup stands out as one of the most widely used methods for plasma generation. The main advantages of GAD plasma compared to other non-thermal plasmas are its high processing efficiency, high electron temperature and density, simple configuration, and the easy control of its process parameters [8][9][10][11][12][13][14][15][16][17][18][19][20]. It has been observed that GAD plasma is very widely used for plasma reforming and fuel and waste treatment [12][13][14][15][16], and it could be also used for bacterial inactivation and food decontamination [10,[17][18][19][20], the creation of plasma-activated water [5,8,21], and surface treatments and modifications [22][23][24][25][26].…”

Gliding arc discharge characteristics such as current and voltage values, the arc column length, discharge duration, density, and type of species produced in the plasma are strongly affected by the geometry and configuration of the electrodes, the experimental parameters, and the type of gas used for the plasma's generation [13,16,18,20].…”

It should be noted that for the application of GAD plasma in the creation of plasma-activated water and the treatment of seeds, plants, or microalgae, the elemental composition of the plasma and the type of species produced play a crucial role [3,8,[19][20][21].…”
