摘　　要：为了研究低速翼型中后部嵌入旋转圆的主动流动控制效果,本文采用数值计算方法对中后部嵌入旋转圆的CLARK-YM18低速翼型进行计算。通过对比分析计算结果,得到在低速翼型的中后部嵌入旋转圆可改变低速翼型的气动特性,旋转圆的转速可控制附近空气的流速,使低速翼型达到增升减阻和减升增阻的双重气动效果;随着旋转圆转速的增大,低速翼型的升力系数和升阻比均近似呈线性关系增大,阻力系数则减小。In order to study the active flow control effects of the low-speed airfoil with a rotating circle where in postmedian,the numerical calculation method is used to calculate with CLARK-YM18 low-speed airfoil where in postmedian embedded rotating circle in this paper.There have some comparison and analysis with calculating data,the result display that it can change the aerodynamic characteristics of low-speed airfoil when a rotating circle is embedded where in postmedian,the speed of the rotating circle can control the velocity of the nearby air,so that low-speed airfoil can achieve the double aerodynamic effect of what increasing lift and reducing drag or reducing lift and increasing drag;Lift coefficient and lift-drag ratio are linearly related to increase with the increase of the rotational speed with rotating circle,and the drag coefficient decreases with increase of the rotational speed with rotating circle.
