摘要：
In order to analyze the effects of turbulence on the aerodynamic performance of a large wind airfoil with low Reynolds number, the aerodynamic performance of a large wind airfoil NREL S810 was systematically studied by wind tunnel test. The lift coefficient, drag coefficient and surface pressure distribution characteristics of the airfoil were obtained. The results show that the existence of turbulence changes the aerodynamic characteristics of S810 airfoil, and the maximum lift coefficient increases first and then decreases. The lift coefficient of S810 airfoil is the highest when the turbulence is 4.6%. With the increase of turbulence, the phenomenon of stall delay occurs, and the stall angle of attack continues to move backward, while the increase of turbulence makes the stall decline curve become flat. © 2023 Tsinghua University.
