| Abstract: |
| In this paper, the flow fields of an airfoil with eddy-flap are described by numerical simulation. The effect of attack angles and the eddy-flap angles on aerodynamic coefficient are studied. The results show that, at low angle of attack, the lift coefficient dropped and drag coefficient raised as the eddy-flap angle increased,. Their relationships are nearly lineal; while at the high angle of attack, the flow separated on the upper surface of the airfoil. The angle of attack increased, the angle of eddy-flap adjusting higher. The stall can be avoided by adjusts the eddy-flap angle properly as the result of flow control. |
