Abstract
Nanosecond repetitive discharges generated by high voltage pulses in a pin-to-pin electrode configuration in atmospheric pressure air are currently used to stabilize lean flames, for the purpose of reducing pollutant concentrations. The goal of this work is to gain an understanding of the plasma-flame stabilization mechanism. Two-photon absorption laser induced fluorescence was employed here for the measurement of atomic oxygen, that is considered to be the key species for stabilization mechanism. Time resolved measurements of the atomic oxygen number density during plasma formation and decay were performed. The hypothesis that the plasma creates reactive O via a two-step mechanism is partially demonstrated.
