摘要	DES turbulence model was used to solve the influence of flap height to the aerodynamic performance of wind dedicated DU95-W-180 airfoil by solving NS equations with numerical methods. The results showed that added a certain height of the flap, the airfoil force appears fluctuate, and the fluctuation range increased with the hight of the flap. The further studies to the reasons causing the phenomenon found that add the flaps, its stall vortex shedding process can cause cyclical changes in pressure around the airfoil, which led to the phenomenon of airfoil force fluctuations.
