Modeling of the production of nitrogen oxide molecules in DC discharges in laminar longitudinal flows of atmospheric‐pressure air is performed. Two‐dimensional nonequilibrium discharge model includes the system of gas dynamic equations and balance equations for various plasma components. Simulations are performed for the discharge currents 50–600 mA and gas flow velocities 1–10 m/s. In considered conditions, the gas temperature in the discharge core varies in the range of 3000–6000 K. Spatial profiles of the densities and fluxes of produced species are obtained, both inside the discharge and in the afterglow region. The energy cost for the production of nitrogen oxides is calculated, depending on the discharge current, gap length, and gas flow velocity. The results of the simulation are compared with available experimental data.

Plasma technology for nitrogen fixation offers a sustainable alternative to traditional fossil fuel‐based methods for fertilizer production. A novel gliding arc plasma reactor is studied for its potential in nitrate fertilizer production, examining its performance across varying gas flow rates, compositions, and pressures (0–2 bar). Results show increased nitric acid (HNO3) production with higher pressure. The reactor achieves a NOx production rate of 10.2 g/h and an HNO3 production rate of 8.83 g/h, with an energy cost of 2.9 MJ/mol of nitrogen. A selectivity of 84% toward NO2 at 2 bar pressure highlights the reactor's efficiency in nitrogen utilization, enhancing its potential for practical applications.
