title = "The effects of repetitively pulsed nanosecond discharges on ignition time in a pulsed detonation engine",
abstract = "An experimental investigation of the effectiveness of a nanosecond duration repetitively-pulsed plasma discharge device for ignition of a pulsed detonation engine was carried out. Ignition of C2H4/air mixtures and aviation gasoline/air mixtures at atmospheric pressure produced a maximum reduction in ignition time of 17% and 25%, respectively, as compared to an automotive aftermarket multiple capacitive-discharge spark ignition system. It was found that the ignition time is reduced as total energy input and pulse repetition frequency is increased. Further investigation of ignition events by Schlieren imaging revealed that at low pulse-repetition frequency (0-5 kHz), individual ignition kernels formed by the discharge do not immediately interact, while at higher pulse-repetition frequencies (≥ 10 kHz) ignition kernels combine and result in a faster transition to a self-propagating flame front.",
