The production process of OH radicals in an atmospheric-pressure streamer discharge is studied. A streamer discharge model is developed to analyse the characteristics of a pulsed positive streamer discharge in point-to-plane electrodes filled with humid air at atmospheric pressure. The results indicate that the behaviour of OH radicals in and after the discharge pulse is characterized by three reaction processes: 'OH-production', 'OH-cycle' and 'OH-recombination'. The first process of OH-production includes dissociation reactions of H2O with O(1D) and N2 , which are the main production processes of OH in the discharge. Immediately after the OH-production process, the OH radicals are destroyed by a reaction with O( 3P) to form O2 and H. Then the subsequent reactions produce OH again through the reaction of H + HO2, which is the OH-cycle process. Finally, the OH radicals are consumed by the OH-recombination process.
