Pulsed streamer discharges have been extensively used in many applications such as control of NOX and SO2 from exhaust gases, treatment of dioxins, removal of volatile organic compounds, generation of ozone and laser excitation. An operation with a high-energy efficiency is necessary for practical applications. It is very important to know the propagation mechanism of streamer discharges in order to improve the energy efficiency of pulsed discharge systems. In this paper, the emission from pulsed streamer discharges in a coaxial electrode system in air at 0.1 MPa was observed using a high-speed gated intensified charge-coupled display camera. A concentric wire-cylinder electrodes configuration was used. Positive and negative pulsed voltages having a width of about 200 ns were applied to the central electrode. From the results, the streamer discharges were initiated at the inner electrode and terminated at the outer electrode. It is suggested that the propagation velocity of the streamer discharges is being influenced strongly by the rise time and the polarity of the pulsed voltage.

“…In order to depict spatiotemporal structures of electron density inside such plasma sources, for example dielectric barrier discharges (DBDs) (Kogelschatz, 2003;Becker et al, 2005) and ns-order short pulsed discharges (Namihira et al, 2003;Walsh & Kong, 2007), it has been confirmed that an amplitude modulation of the kHz-order applied voltage at a frequency of a few hundreds Hz and additional measurement of a millimeter-wave (mm-wave) transmission method are effective.…”

“…From the streak image of a pulsed streamer discharge in a coaxial electrode geometry [48,49], the propagation process of the pulsed streamer discharge is that the primary streamer initiates in the vicinity of the central rod electrode and then propagates toward the grounded cylinder electrode. When the primary streamers lose contact with the central rod electrode, secondary streamers initiate in the vicinity of the central rod electrode since the electric field at the central rod surface becomes high enough to generate streamers with the disappearance of the interaction between the electric fields of the central rod electrode and the primary streamers.…”

A review of mainly the past two years is undertaken of the industrial applications of pulsed power. Repetitively operated pulsed power generators with a moderate peak power have been developed for industrial applications. These generators are reliable and have low maintenance. Development of the pulsed power generators helps promote industrial applications of pulsed power for such things as food processing, medical treatment, water treatment, exhaust gas treatment, ozone generation, engine ignition, ion implantation and others. Here, industrial applications of pulsed power are classified by application for biological effects, for pulsed streamer discharges in gases, for pulsed discharges in liquid or liquidmixture, and for material processing.Index Terms -Pulsed power, industrial application, bioelectrics, exhaust gas treatment, discharge in liquid, material processing.
