Discharge regime transition in a single pulse can present the breakdown mechanism of nanosecond pulsed dielectric barrier discharge. In this paper, regime transitions between streamer, diffuse, and surface discharges in nanosecond pulsed dielectric barrier discharge are studied experimentally using high resolution temporal–spatial spectra and instantaneous exposure images. After the triggering time of 2–10 ns, discharge was initiated with a stable initial streamer channel propagation. Then, transition of streamer-diffuse modes could be presented at the time of 10–34 ns, and a surface discharge can be formed sequentially on the dielectric plate. In order to analyze the possible reason for the varying discharge regimes in a single discharge pulse, the temporal–spatial distribution of vibrational population of molecular nitrogen N2 (C3Πu, v = 0,1,2) and reduced electric field were calculated by the temporal–spatial emission spectra. It is found that at the initial time, a distorted high reduced electric field was formed near the needle electrode, which excited the initial streamer. With the initial streamer propagating to the dielectric plate, the electric field was rebuilt, which drives the transition from streamer to diffuse, and also the propagation of surface discharge.

AbstractRecently industrial applications of ozone have increased in widely different areas including oxidation, sterilization, deodorization, bleaching and others. Especially, a demand of movable ozonizer for treatment of diesel exhaust gas has been growing up. Generally, a generation of ozone has been attained using ultra violet irradiation, electrolysis and electrical discharges such as a dielectric barrier discharge, a surface discharge, a pulsed streamer discharge and a superimposed silent and surface discharge. In the present situation, a ozonizer based on a dielectric barrier discharge has been commonly utilized in the world. However, a ozonizer based on a dielectric barrier discharge has disadvantages as a movable ozonizer since a discharge electrode, having a breakable dielectric layer and a sensitive gap separation, does not have enough resistance to vibration stress. In this study, the characteristics of ozonizer based on a pulsed streamer discharge were measured using a magnetic pulse compressor (MPC), which has a maximum output voltage of 60 kV, a maximum pulse repetition rate of 500 pulses per second and a pulse duration of about 130 ns, and discharge reactors with coaxial geometry. For the reactor of pulsed streamer discharges, an anode and a cathode electrodes are made by metallic material and a gap separation between electrodes has a little influence on a discharge condition. Therefore, this type of ozonizer has a merit to apply mobile situation. As the results, the ozonizer based on the pulsed streamer discharges has the better production yield of 150 g/kWh in the concentration range of 10 to 20 g/m

The Difference

This project is concerned with surface dielectric barrier discharge (DBD), which involve designing the configuration of discharge and experiment, collecting and analysis data from experiment and simulation. Therefore, this report includes the objective of the project and general information of background. It also briefly introduces the history and theory of dielectric barrier discharge. For the experiment how to design the discharge implement and why. Then it will show the experiment in different configurations, and the analysis data collected in experiment also explain the data for finding out the properties of surface dielectric barrier discharge and what the difference between surface discharge and vertical discharge are. High frequency power supplied will be used for viewing the phenomenon of discharge. Compare the spectrums of discharge on dielectric and air discharge. Finally, it is the main conclusions and introduction of the difference of surface dielectric barrier discharge and vertical discharge. There are some conclusions. Discharge voltage increase linearly with applied voltage. Discharge power increase non-linearly with the discharge voltage. The gap of high voltage electrodes will not affect discharge voltage and discharge power. Discharge power increases with the frequency of power supply. Discharge area will expand when the applied voltage increases.
