Abstract
Effects of the non-equilibrium plasma superposition on the ammonia / oxygen / nitrogen unburned premixed gas was investigated to improve the laminar burning velocity of the ammonia flame. The plasma-assisted combustion is the one of the methods to improve the combustion characteristics. In this study, the dielectric barrier discharge (DBD) was focused and the effect of the DBD on the burning velocity was experimentally investigated. Results indicated that the burning velocities became faster with increasing the peak to peak voltage of DBD. The largest improvement of the burning velocity was observed at the stoichiometric condition.
