In this study, the spatial distributions of the emission intensity of OH (A2Σ → X2Π, 0-0) and N2+ (B2Σu+ → X2Σg+, 0-0, 391.4 nm) are investigated in the atmospheric pressure pulsed streamer discharge of H2O and N2 mixture in a needle-plate reactor configuration. The effects of O2 flow rate on the spatial distributions of the emission intensity of OH (A2Σ → X2Π, 0-0), N2+ (B2Su+ → X2Σg+, 0-0, 391.4 nm), and the vibrational temperature of N2 (C) in the lengthwise direction from needle to plate are attained. It is found that the emission intensities of OH (A2Σ → X2Π, 0-0) and N2+ (B2Σu+ → X2Σg+, 0-0, 391.4 nm) decrease with increasing O2 flow rate. In the direction from needle to plate, the emission intensity of OH (A2Σ → X2Π, 0-0) decreases firstly, and rises near the plate electrode, while the emission intensity of N2+ (B2Σu+ → X2Σg+, 0-0, 391.4 nm) is nearly- constant along the needle to plate direction firstly, and rises sharply near the plate electrode. The main physicochemical processes involved are discussed.
