| 摘 要： | 进行了翼型深度动态失速及基于DBD介质阻挡放电等离子体激励器的流动控制技术数值模拟研究。将激励器对流动空气的作用以彻体力源项形式加入N-S方程。通过数值求解此N-S方程,研究了DBD激励器对NACA0012翼型俯仰运动深度动态失速的控制作用;研究了DBD激励器工作方式对动态失速平均气动力、气动力迟滞曲线的影响,提出了控制效果较好的激励器工作方式。

| Abstract: | Numerical investigation of flow control on NACA0012 airfoil deep dynamic stall based on DBD plasma actuators was presented. The effects of the plasma actuator on flows were incorporated into Navier Stokes computations as a body force source item. Cycle-integrated aerodynamic force and hysteresis curve on three kinds of control modes were numerically investigated. |
