摘要：

Here, we addressedthe airflow control via surface dielectric discharge(SDBD) plasma at atmospheric pressure. The influence of the generation conditions of SDBD non-thermal plasma, including but not limited to the materials of dielectric and electrode, dielectric thickness, electrode s structure and discharge voltage, on the plasma evolution, airflow velocity, and surface potential was experimentally investigated. The preliminary results show that the SDBD plasma generation conditions all have a major impact on the airflow control. To be specific, the asymmetric, parallel filamentary discharge occurs mainly in the negative cycle of voltage and becomes stronger with a sharp-edged electrode; a thicker dielectric has stronger mechanical strength, higher stability, and heightens plasma wind because it can stands safely a high voltage. A bigger dielectric constant and an allowable higher discharge voltage produce stronger plasma wind. The optimized conditions, including a 1.0 mm thick mica, an electrode of sharp stainless steel blade, and a discharge voltage of 16 kV, significantly enhance the plasma wind. ©, 2015, Science Press.
