摘要
针对目前国内外对沿面型介质阻挡放电及其应用的研究多集中于体积力和诱导气流的速度上,而对其应用条件下的放电特性研究不足,在空气流速0~20m/s范围内研究了气流对不同激励电压沿面型介质阻挡放电的影响,讨论了气流对放电影响的机制。通过对放电电流和放电电压的测量,分析了气流对最大放电电流、放电功率的影响;通过采集不同来流速度下的放电图像,分析了放电强度、放电均匀性及放电形态。在此基础上综合分析了气流中SDBD的物理规律,结果表明随气流速度的增大,等离子体放电强度减弱,放电变得均匀,最大放电电流和功率都逐渐减小。该研究结果对提高沿面型介质阻挡放电等离子体激励器放电强度及其流动控制能力具有一定的参考作用。
At present,the research on the surface dielectric barrier discharge and its application at home and abroad mostly focus on the body force and the velocity of induced airflow,but the research on the discharge characteristics under its application conditions is insufficient.In this paper,the influence of airflow on the surface dielectric barrier discharge of different excitation voltages is studied in the range of air flow rate from 0 to 20 m/s.The mechanism of the influence of airflow on discharge is discussed.The effects of air flow on the maximum discharge current and discharge power are analyzed by measuring the discharge current and discharge voltage.The discharge intensity,discharge uniformity and discharge pattern are analyzed by collecting discharge images at different incoming flow rates.On this basis,the physical laws of SDBD in the airflow are comprehensively analyzed.The results show that as the airflow speed increases,the plasma discharge intensity decreases,the discharge becomes uniform,and the maximum discharge current and power are gradually reduced.The results of this study have a certain reference value for improving the discharge intensity and flow control ability of the surface dielectric barrier discharge plasma actuator.
