| 摘 要： | 用数值模拟方法研究了旋涡对翼型的气动干扰。出发方程是N-S方程。数值格式为Beam-Warming格式。结果表明,旋涡位置改变,其对翼型的气动(激波和升力)干扰随之有显著变化;涡的有利干扰可使翼面上流动分离受到一定程度的控制,导致翼型升力增大;涡的位置和强度的合理组合能有效地提高升力。计算还表明,单一旋涡扫过翼型时平均升力将提高50％左右。

| Abstract: | In this paper, the aerodynamic interaction of a vortex with stationary airfoil is studied by numerical simulation. The Beam-Warming implicit algorithm is used to solve Navier-Stokes equations. The investigation includes the influence of a concentrated vortex on shock and separation; the results show that the location of vortex can induce the change of the lift and shock, the separation can be controlled and lift can be increased by the favourable combination of vortex strength and its location. |
