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<5×10~5)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 surface pressure measurement system was used to study the low Reynolds number (Re <5 × 10 ~ 5) aerodynamic characteristics of S809 wind turbine dedicated airfoil in a small return-flow low-speed wind tunnel. The experimental results show that the air- Reynolds number of the pressure rise, resistance and surface pressure distribution characteristics. It will provide data support for the design of small wind turbine blades and related research, and fill in the blank of aerodynamic characteristics data of low profile airfoils.
