在较高风速下研究介质阻挡放电等离子体气动激励对翼-身组合体绕流流动的控制效果。结果表明:在来流风速100m/s的情况下,介质阻挡放电等离子体气动激励能较好地抑制流动分离,失速迎角推迟约30%,升阻比最大提高80%。研究结果为等离子体流动控制技术的应用奠定重要基础。
The effect of aerodynamic actuation of dielectric barrier discharge plasma on the flow around the wing-body assembly was investigated at higher wind speeds. The results show that the aerodynamic activation of dielectric barrier discharge plasma can restrain the flow separation well at the incoming flow velocity of 100m / s. The stall angle of attack is delayed by about 30% and the lift-drag ratio is increased by 80% at maximum. The research results lay an important foundation for the application of plasma flow control technology.
