摘要 通过数值求解二维非定常可压N-S方程,研究了二维翼型上扰流片快速张开诱发的复杂非定常流动问题。利用动态重叠网格方法处理扰流片和主翼相对移动,分析了扰流片快速张开诱发的升力过冲现象及其形成机理。着重探讨了来流攻角和扰流片高度对过冲量的影响。 Transient aerodynamic response of an airfoil to a rapidly deploying spoiler is numerically investigated by solving two - dimensional unsteady compressible Navier - Stokes equations. The spoiler moving relative to a stationary airfoil is treated by a dynamic overset grid method. The mechanism of the adverse lift because of the rapidly deploying spoiler is analyzed. As a primary purpose, the effect of angle of attack and height of spoiler on the unsteady flows are investigated.
