Reactive Nitrogen Species Production by Series Arc Discharge Plasma Jet

Atmospheric pressure nitrogen series-arc discharge (SAD) plasma jet, under the influence of an external magnetic field, was used for $\text{NO}_{\mathrm{x}}$ synthesis. The optical emission spectroscopic (OES) technique was employed for the estimation of the nitrogen SAD plasma properties. The properties include rotational $(\mathrm{T}_{\mathrm{r}})$, and vibrational $(\mathrm{T}_{\mathrm{v}})$ temperatures, electron excitation temperature $(\mathrm{T}_{\mathrm{e}\mathrm{x}})$, and electron density $(\mathrm{n}_{\mathrm{e}})$. It is found that $\mathrm{T}_{\mathrm{r}}, \mathrm{T}_{\mathrm{v}}, \mathrm{T}_{\mathrm{e}\mathrm{x}}$, and $\mathrm{n}_{\mathrm{e}}$ are increased slightly both in the absence $(\mathrm{B}=0)$, and presence $(\mathrm{B}\neq 0)$ of magnetic field (B), with the increase in applied voltage. The increments of these plasma parameters can likely be occurred due to the increase in applied voltage. Because, the electrons gain more energies from the enhanced electric field. On the other hand, these plasma parameters are also enhanced due to the presence of $\mathrm{B}$ with respect to zero magnetic fields. This may happen due to the reduction of diffusion loss of electrons because magnetic field inhibits the movement of electrons in the radial direction. Further, the electrical power dissipation in the plasma is slightly decreased in the presence of magnetic field. For all other applied voltage, similar phenomena happened. This result may imply that the energy cost for synthesizing $\text{NO}_{\mathrm{x}}$ in water will be reduced.
