摘要

为研究前缘小翼对风力机翼型抗风沙冲蚀性能的影响,采用RANS方程耦合离散项DPM模型开展风力机翼型风沙环境下的数值模拟研究。研究表明适当位置加装前缘小翼能够实现在提升翼型气动性能的同时增强翼型的抗风沙冲蚀磨损能力,在前缘小翼弦长25 mm,与主翼型相对距离为125 mm圆弧范围内安装前缘小翼能获得良好的抗冲蚀磨损效果,但在部分安装位置会出现失速攻角减小的情况。通过对比不同主翼型下前缘小翼的抗风沙冲蚀磨损性能,研究发现前缘小翼的抗风沙冲蚀磨损作用更适用于非对称翼型并能使相对厚度较大的翼型磨损量后移。

Abstract

In order to investigate the effect of leading edge auxiliary airfoil on the wind-sand erosion resistance of wind turbine wing shapes, the numerical simulation of wind turbine airfoil in a sandy environment was carried out by using the RANS equation coupled with the discrete term DPM model. Research results show that installing a leading edge auxiliary airfoil in an appropriate position can enhance the aerodynamic performance of the airfoil while enhancing its resistance to wind-sand erosion and wear. The installation of leading edge auxiliary airfoil within the chord length of 25 mm and the relative distance of 125 mm from the main airfoil can obtain good erosion and abrasion resistance, but the stall angle of attack way be reduced in some of the installation positions. By comparing the wind-sand erosion performance of leading edge auxiliary airfoils under different main wing shapes, it is found that the wind-sand erosion effect of leading edge auxiliary airfoil is more suitable for asymmetric airfoils and can shift backward the erosion amount of airfoils with larger relative thicknesses.
