摘　　要：为了提高典型沿面DBD平板激励器诱导气流速度,通过实验研究了典型DBD平板激励器表面的磁场分布,提出了在DBD平板激励器的上、下电极之间夹进平面线圈,运用电磁耦合原理增强等离子体激励器放电效果,从而加速DBD等离子体诱导气流的方法。探究了不同结构参数的电感线圈产生的电磁耦合作用对大气压下平板式DBD等离子体激励器放电加强的效果,以及夹进平面线圈后加载电源的电压和频率对DBD放电的影响,并利用粒子图像测速技术测量了电磁耦合作用下典型DBD等离子体诱导气流流场,考察了其中电磁耦合对加速诱导气流的作用。实验结果表明,运用电磁耦合作用可在一定程度上增强等离子体激励器的放电效果,一些电感线圈产生的电磁耦合作用可显著改善DBD等离子体诱导气流的连续性和加厚流场区域。To accelerate the flow induced by typical surface DBD actuator, we studied the magnetic distribution on the surface of a typical DBD actuator qualitatively through experiments. We proposed a method that inductance coils between the upper electrode and the lower electrode were installed to enhance the discharge and increase the flow speed due to the electromagnetic coupling applied to the plasma actuator. Inductance coils with different structure parameters which could create various electromagnetic coupling impacts were used to improve the DBD plasma discharge. Furthermore, we measured the induced flow charts of DBD plasma actuators with electromagnetic coupling using the particle image velocimetry to study the electromagnetic coupling impact on increasing the flow speed induced by DBD plasma. The results show that, by applying electromagnetic coupling to the typical DBD plasma actuator, its discharge can be improved and the airflow induced by the plasma can be accelerated by some kinds of inductance coils, improving the induced flow in both continuity and thickness.
