@article{(Open Science Index):https://publications.waset.org/pdf/10007054, title = {Characteristics of Ozone Generated from Dielectric Barrier Discharge Plasma Actuators}, author = {R. Osada and S. Ogata and T. Segawa}, country = {}, institution = {}, abstract = {Dielectric barrier discharge plasma actuators (DBD-PAs) have been developed for active flow control devices. However, it is necessary to reduce ozone produced by DBD toward practical applications using DBD-PAs. In this study, variations of ozone concentration, flow velocity, power consumption were investigated by changing exposed electrodes of DBD-PAs. Two exposed electrode prototypes were prepared: span-type with exposed electrode width of 0.1 mm, and normal-type with width of 5 mm. It was found that span-type shows lower power consumption and higher flow velocity than that of normal-type at Vp-p = 4.0-6.0 kV. Ozone concentration of span-type higher than normal-type at Vp-p = 4.0-8.0 kV. In addition, it was confirmed that catalyst located in downstream from the exposed electrode can reduce ozone concentration between 18 and 42% without affecting the induced flow.}, journal = {International Journal of Mechanical and Mechatronics Engineering}, volume = {11}, number = {3}, year = {2017}, pages = {698 - 707}, ee = {https://publications.waset.org/pdf/10007054}, url = {https://publications.waset.org/vol/123}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 123, 2017}, }
