IGNITION ENHANCEMENT BY USING NONEQUILIBRIUM PLASMA IN SUPERSONIC FLOW

摘要

The authors developed dielectric barrier discharge (DBD) device to generate nonequilibrium plasma for ignition enhancement. The nonequilibrium plasma was generated in a supersonic flow with small electric power. The discharge occurred with smaller applied voltage in a higher Mach number flow. Spectroscopic measurement showed that the main emission spectra of the DBD plasma were from excited N_2 and N_2~+.
