An Experimental Evaluation on Ozone Generation by Local Discharge Type Gas Jets

A new type ozone generator with local dielectric barrier discharges operated in very thin gas jets has been experimentally investigated for evaluating an efficient generation process of the ozonic atmosphere. The use of gas jets is to improve an enhancement of the barrier discharges and a cooling effect on the efficiency. The experiments have been conducted to characterize the ozone generation process under following variable parameters: inputted discharge power from a high-voltage source, flow rate of the injected gas jets, and discharge electrode arrangements for optimizing the efficiency. In this paper, a fundamental design of the ozone generator and some quantitative results are presented. The experimentally obtained evaluation indicates an effective performance for the efficiency in a lower range of discharge power.
