分离点的位置随着攻角和马赫数的变化而变化。

The frequency of vortex shedding and the position of separation are affected by the incidence and Mach number.

前缘缝翼优化时，用主翼面上的分离点位置作为间接目标函数；

For the optimization of a leading-edge slot, the separating position of the main element is used as indirect target function for optimizing caculation;

对后缘襟翼则分别以翼型升力值和分离点位置作为间接目标函数，进行优化计算。

And for that of a trailing-edge flap, the lift of the airfoil or separating position at the key airfoil element is used.

通过理论分析和数值模拟确定了实验控制的关键参数，实现了电磁力消涡和增涡的连续控制，电磁力作用下的圆柱绕流的分离点可以在前驻点和后驻点之间变动。

The key parameters of the experimental controlling have been confirmed by theoretical analysis and numerical simulation. The electrodes and the permanents are flush mounted on the cylinder surfac…
