Planar Laser-Induced Fluorescence Diagnostics for Spatiotemporal OH Evolution in Pulsed Corona Discharge
(2013) In IEEE Transactions on Plasma Science 41(3). p.485-493- Abstract
- OH radicals play an important role in pollutant removal in nonthermal plasmas. It is crucial to clarify the behavior of OH radicals in this process. A time-resolved 2-D OH radial distribution was investigated in a pulsed corona discharge by planar laser-induced fluorescence at atmospheric pressure and room temperature. The OH evolutions under different gas components were studied, and the evolution process was simulated. The OH decay processes were found to be divided into two periods: a fast decay period and a slow decay period. The O, N, and HO2 are dominant radicals for OH generation and decay. The OH radicals are mainly generated near a nozzle electrode. The concentration variations of O-2, NO, and H2O in the background gas led to... (More)

The OH radicals are mainly generated near a nozzle electrode. The concentration variations of O-2, NO, and H2O in the background gas led to different OH density evolutions. The OH distribution zones were different as gas components varied. Themaximum area of OH radical distribution after discharge decreased by 20% as O-2 increased from 5% to 8%, and it decreased by 69% as NO (150 ppm) was added into the background gas. (Less)
