Abstract :
Hydroxyl (OH) radicals generated in wire-plate pulsed corona discharge (PCD) were detected by laser-induced fluorescence (LIF). In this paper, the 2-D distribution of OH radicals and the time-resolved development of the streamers in humidified nitrogen were recorded by an intensified charge-coupled device camera. The results indicate that the OH-LIF signals could not be detected when secondary streamer was absent in PCD with low input energy. Input energy, which varies with the configuration of wire-plate reactor and applied voltage, significantly affected the spatial distribution of OH radicals.
