摘要

An electrodynamic model of a combustion chamber in which an initiated subcritical streamer discharge is used for the ignition of a combustible mixture is considered. For the localization of a discharge in the working space of the chamber, several initiators based on the half-wave electromagnetic vibrators with resonant properties, are used. A combustion chamber with multipoint microwave ignition of a propane–air mixture was calculated using an approximate three-stage numerical model of the microwave plasma action on a fuel mixture for its ignition. The discrepancy between the calculation and experimental data on the amplitude of oscillations of the pressure in this chamber comprises about 10%. The reasons for this discrepancy are discussed.
