| 摘 要： | 采用数值模拟方法对NACA23012,NACA4412,S809,S810等4种常用风力机叶片翼型进行了研究,分析了翼型静止与振荡时的气动性能.随着攻角的增加,静止翼型的升力系数先增大后减小,其阻力系数一直增大,显示出NACA4412翼型具有较好的低风速启动性能；振荡翼型的升力系数随着攻角的变化呈现一个闭合迟滞环曲线,显示出振荡翼型S809的动态失速迟滞效应最为明显.文章参照模拟结果和对比试验数据,验证了数值模拟的可靠性.

| Abstract: | Four kinds of aerofoil of wind turbine blade which are NACA23012,NACA4412,S809 and S810 were studied by numerical simulation method,and the aerodynamic performance of the static and oscillate aerofoil was analyzed.With the angle of attack becoming larger,the lift coefficient of the static aerofoil first increased and then decreased,however,the drag coefficient continuously increased.It showed NACA4412 aerofoil had a better low-speed start-up performance.The lift coefficient curve of the oscillate aerofoil w... |
