介质阻挡放电微等离子体致动器在约1.4 kV的低放电电压下通电用于流动改性。由于微等离子体的产生，在不同的占空比的施加电压的流速表现出不同的特性。用高速摄像机的观察显示了在不同的时间间隔，由于微等离子体的流动的修改。采用Suzen模型对流动进行了数值模拟，该模型假设等离子体激励器的电势可以分解为外电场引起的电势和等离子体电荷密度引起的电势。
Dielectric Barrier Discharge microplasma actuator energized at low discharge voltage at about 1.4 kV was applied for flow modification. Due to the microplasma generation, the flow velocity showed different characteristics at various duty ratios of the applied voltage. The observation with the high speed camera showed at various time intervals the modification of the flow due to the microplasma. The numerical simulation of the flow was carried out using Suzen model which is assuming that the electric potential of plasma actuator potential can be split in the potential due to the external electric field and potential due to the charge density of plasma.
