Abstract :
Pulsed corona (PC) offers real promise for the degradation of pollutants in gas and water streams. Understanding discharge physics is necessary for developing corona applications. This paper presents an investigation of the dependence of PC current and radiation on pulse repetition rate (PRR). The study was carried out in a wire-to-wire geometry. A corona device with a central high-voltage electrode and two symmetrical grounded electrodes was used for model experiments. A nanosecond solid-state pulse generator SM-2N (100 kV, 5 ns, PRR up to 300 Hz) was used for driving PC discharge. A model expression relating the removal efficiency with PRR is presented. The removal efficiency falls with the increase of PRR at a "constant" flow rate or "constant" residence time. There is satisfactory agreement between the calculated data and the experimental results
