Energy Injected in Multi-tip Pulsed Corona Discharge Reactor in Air at Atmospheric Pressure for Pollution Control

This work is devoted to the analysis of experimental and calculated results obtained in dry air at atmospheric pressure in positive pulsed multi-tip corona discharges. The maximum corona current is analysed as a function of several parameters such as the gap distance, the applied voltage and the anodic tip number. The energy injected in the discharge is also calculated as a function of the above parameters for to optimize the most efficient configuration for the pollution control. Also, the average propagation velocity is discussed as a function of the same operating parameters (gap distance, applied voltage and anodic tip number). Intensified Charged-coupled device pictures are shown to prop up the results obtained in this study.
