Surface Dielectric Barrier Discharge

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.
