誘電体表面温度がプラズマアクチュエータの性能に与える影響

抄録

To mitigate the impact of low-concentration methane with a high global warming potential and that is difficult to recycle, the use of plasma actuators (PA) has been explored. This is because PA can generate airflow without moving parts as well as oxidize substances in the air. To achieve high energy efficiency in the treatment, PA should be used in combination with catalysts at a high dielectric temperature. Therefore, the purpose of this study is to investigate the effect of the surface temperature of the dielectric on the performance of PA. A heat-resistant PA capable of withstanding high temperatures, made of alumina dielectric, was created for this study. As a result, it was confirmed that the higher the surface temperature, the faster the flow velocity and the wider the acceleration region. Observation of discharge images using an ICCD camera also showed that area of negative polarity discharge expanded as the temperature increased.
