Investigation of the temperature and electron density of the gliding arc discharge plasma by optical emission spectroscopy

This paper generated a gliding arc discharge plasma at atmospheric pressure by building a system with two electrodes arranged in the shape of an inverted V by applying a high voltage (HV) differential between the electrodes. The main objective of this paper is to study the effect of changing the flow rate of the gas (5-10-15–20-25 L/min) and changing the spacing between the electrodes (2-4-6-8 mm) on the non-thermal precisely measuring plasma properties via a process comprehensive optical emission spectroscopy (OES) spectroscopic examination. The electron temperature (Te), electron density (ne), and other values were computed using the Boltzmann plot technique. And other plasma properties. For varying gas flow rates, the electron temperature varied between 0.8604 and 1.3328 eV, while the electron density varied between 1.8186 and 2.313 \({\text{m}}^{-3}\) ${\text{m}}^{-3}$ . By contrast, the electron density varied between 0.09711 and 0.451 \({\text{m}}^{-3}\) ${\text{m}}^{-3}$ while the electron temperature varied between 0.686 and 1.0866 eV with the average distance between the electrodes. It can be seen that the plasma properties show an increase with both the rise in the flow rates of argon gas and the increase in the distance between the electrodes.
