采用粒子图像测速技术, 获得了不同环境压力下介质阻挡放电等离子体诱导流场启动涡随时间的演化规律和诱导流场分布的变化规律. 实验表明: 不同环境压力下, 诱导流场都会出现启动涡, 压力较高, 启动涡逐渐向右即向植入电极一侧扩散并最终消失, 扩散速度随时间递减, 压力较小, 诱导漩涡不会随放电时间的增大而消失; 环境压力减小, 等离子体诱导流场的启动时间减小, 诱导流场的法向分量增强、横向分量减弱, 诱导流线形状的变化规律是:L→U→V, L 型流线没有诱导漩涡, U 型流线有两个诱导旋涡, 分别分布在U 型凹槽和右侧, V 型流线有一个诱导漩涡, 分布在V 中间.The evolutions of dielectric barrier discharge (DBD) plasma induced starting vortex and the transformation of the DBD plasma induced flow field at different operating pressures are obtained by particle image velocimetry. The results show that the starting vortex will diffuse to the embedded electrode side and then disappear, and the diffusivity will decrease as the time goes on at high operating pressure. But the starting vortex will not change in location, and it will not disappear at low operating pressure. As the operating pressure decreases, the starting time of plasma induced flow field decreases, the ordinate orientation of the induced flowfield increases, and the landscape orientation of the induced flowfield decreases. The form of the induced streamline will come through L→U→V as the pressure decreases. There is no induced vortex in the form of L. There are two induced vortexes in the form of U which lay in the middle and on the right hand of the form U respectively, and there is one induced vortex in the form of V which lays in the middle of form V.
