Abstract

The process of flow control in the swept-wing boundary layer using a number of plasma actuators mounted at an angle to the leading edge is theoretically studied. The resonance response of the controlled flow is investigated when the angle of inclination of the actuators is close to the angle of inclination of the stationary vortices of cross-flow instability. The calculation of the controlled flow is carried out within the framework of the parabolic system of Navier–Stokes equations. The stability characteristics of periodic flows formed by the action of a control bulk force are calculated.

等离子体驱动器周期序列对后掠翼边界层流动控制的共振影响

从理论上研究了若干等离子体致动器与前缘成一定角度对后掠翼边界层内流动的控制过程。研究了当致动器的倾斜角度接近横流不稳定静涡的倾斜角度时，被控流的共振响应。控制流的计算是在抛物型Navier-Stokes方程组框架内进行的。计算了由控制体力作用形成的周期流的稳定性特性。
