中文摘要：
通过求解三维Navier-Stokes方程,模拟计算了细长体大迎角非对称涡流动,利用在物体表面加扰动块和微吹气的控制方法,分析了大迎角细长旋成体背风涡的结构及侧向力变化的流场因素。结果表明：加扰动块可以将细长体的非定常流动变为有规律的、确定的非定常流动,加微吹气扰动可以很好地控制细长体背风涡的非对称性。计算结果与实验结果进行了对比,并得到较满意的结果。
英文摘要：
By solving three-dimensional Navier-Stokes equations, Asymmetrical vortex flow over the slender body at high angles of attack is simulated. Surface disturbance in the block and tiny blowing control method are also used for analyzing the high angle of attack slender body leeward vortex structure and lateral force changes. Results show that the tiny block can add disturbance, and in this way, the unsteady flow over the slender body becomes disciplinary and steadily unsteady flow. Tiny blowing disturbance can also have a good control of the slender body non-symmetry vortex. Calculated results agree well with the experimental data.
