采用表面压力测量系统,在小型回流式低速风洞中开展了S809风力机专用翼型的低雷诺数(Re＜ 5×105)气动特性实验研究,获得了自由和固定转捩条件下不同雷诺数的压差升、阻力和表面压力分布特性.将为小型风力机叶片设计及相关研究提供数据支撑,并填补了该翼型低雷诺数气动特性数据的空白.
The experimental study on aerodynamic characteristics of S809 dedicated wind turbine airfoil at less than 5×105 Reynolds numbers was carried out with a surface pressure measurement system in a small,closed-circuit,low-speed wind tunnel.The characteristics including pressure lift and drag coefficients,surface pressure distribution were obtained at some low Reynolds numbers under free and fixed transition conditions.The results will be helpful to the design of small wind turbine blades and some related researches,which also filled the data gaps of S809 airfoil.
