Abstract

In presented work the influence of dielectric barrier thickness on the parameters of Diffuse Coplanar Surface Barrier Discharge was investigated. The discharge was operated at atmospheric pressure laboratory air. The electrical parameters of the system were studied both experimentally and using numerical simulations. The discharge pattern was studied as well using intensified CCD camera.

Highlights

  • Dielectric barrier discharges (DBDs) have been known to the scientific community for more than 150 years [1, 2]

  • The ozone production ratio depends strongly on the gas temperature, as ozone decays considerably with increasing temperature [4]. Because of their thermal nonequilibrium nature [5], and since the storage and transportation of ozone poses serious hazards, DBDs have been under continuous investigation for ozone production

  • This paper presents a study of the practical impacts of dielectric barrier thickness on the parameters of diffuse coplanar surface barrier discharge (DCSBD) by means of electrical measurements and highspeed ICCD camera imaging

Summary

Introduction

Dielectric barrier discharges (DBDs) have been known to the scientific community for more than 150 years [1, 2]. Since their invention, DBDs have been used extensively for ozone generation [1, 3]. The ozone production ratio depends strongly on the gas temperature, as ozone decays considerably with increasing temperature [4]. Because of their thermal nonequilibrium nature [5], and since the storage and transportation of ozone poses serious hazards, DBDs have been under continuous investigation for ozone production. DBDs have been tested as tools for plasma medicine [11, 12] or for bio-decontamination (sterilization) of surfaces [13, 14]
