“…An important feature of the developed model is the dependence of plasma effects on the parameters of the microwave system (heating and an additional set of reactions), which is achieved through additional preliminary simulation steps. A microwave subcritical streamer discharge is characterized by volumetric action, reaching high electron concentrations [23]. The use of propane is explained by the presence of reliable detailed combustion schemes (using Grimech 3.0).…”

“…Due to the use of the resonant method of amplifying the electric field, these discharges ignite at the initial field strength much lower than the breakdown energy Ecr. Detailed studies of such discharges carried out during the last 20 years at the RAS of the Russian Academy of Sciences have shown that the abovementioned method is 20 to 80 times higher in terms of energy costs than other methods, including corona discharge and spark ignition [1,2].…”

Thermodynamic analysis shows that for flights with velocities exceeding six sound velocities, it is required to burn fuel not in a subsonic but in a supersonic flow. The aim of this work is to investigate the possibility of creating a stationary combustion front in a supersonic flow by igniting the mixture with an attached microwave discharge. Discharges are created on the resonator by means of a pulsed source of quasi-optical microwave radiation. This method of initiation is one or two orders of magnitude more economical than other known methods of plasma ignition and combustion stabilization. A numerical evaluation and comparison with experiment of the propagation velocity of a subcritical streamer discharge in a stationary medium and in a supersonic drifting flow are performed. Experiments have been conducted to ignite a flat flow of propane-air mixture, as well as ignition of the propane stream fed into the airflow, which simulates the operation of the fuel injector. In all cases, the experiments confirmed a steady fuel combustion, which was controlled by the temperature measurements with a thermocouple.
