摘要：
In order to improve the performance of wind turbine blades, a bionic design method was proposed based on the good aerodynamic characteristics of the swallow wing. The performance of the airfoil imitating the swallow wing was simulated and compared with the standard wind turbine airfoil using computational fluid dynamics technique. The results show that the bionic airfoil has higher lift coefficient and lift-drag ratio than the standard airfoil. The bionic blade was designed using the airfoil of the swallow. Numerical simulation and experiment for the wind turbine blade were carried out. Results show that the airfoil of the bionic blade has bigger pressure difference between the upper and lower surfaces, which can provide stronger lift. The efficiency of the bionic blade increases by 25% compared with that of the standard blade. ©, 2015, Jilin Daxue Xuebao (Gongxueban)/Journal of Jilin University (Engineering and Technology Edition).
