摘要：
This paper investigates the aerodynamic performance of the wind turbine airfoil with Magnus leading circle under low Reynolds number condition. The influences of the critical parameters such as the velocity ratio, clearance, radius and location on the boundary flow and lift drag performance are analyzed by numerical method. Based on the Latin hypercube and Kriging model, an implicit non-linear response model is established to quantify the influence of Magnus effect. The optimized Magnus airfoil is obtained by employing genetic algorithm. Results show that Magnus effect has a significant effect on aerodynamic characteristics of wind turbine airfoils at low Reynolds number. The radius has a greatest influence on lift-drag ratio, the effect of the velocity ratio is slightly weaker, and the effect of location is the smallest. The lift-to-drag ratio is positively correlated with velocity ratio and negatively correlated with radius and clearance and location. Compared with the baseline airfoil, the maximum lift-drag ratio of the optimized Magnus airfoil is increased by 40.31% with a velocity ratio of 1.33, a clearance of [0.003C, ] and a radius of [0.046C.] The stall angle is delayed from 10 degree to 14 degree. © 2021, Solar Energy Periodical Office Co., Ltd.
