摘要 本文通过数值计算,研究了一种前缘为可转动圆柱的二维S809翼型的气动性能。研究表明,通过驱动前缘圆柱旋转,可有效抑制翼型吸力面的流动分离,使得翼型在较大攻角下具有良好的气动性能,提高了翼型的最大升力系数与升阻比。该流动控制方法具有简单有效、花费代价小等优点。 The aerodynamic performance of the two dimensional S809 airfoil with a rotating cylinder in the leading edge is investigated numerically.The study shows,the separation can be suppressed efficiently in the suction side of the airfoil by driven the cylinder to rotate.As a result,the airfoil can make a good performance even under large angle of attack,and higher maximum lift coefficient and lift-drag coefficient can be acquired.The energy cost to drive the cylinder is almost neglectable.
