以风力机专用翼型S809为研究对象
采用离散相模型(DPM)耦合动网格的数值方法以及高斯滤波
研究了清洁来流下2°~12°攻角范围内
沙尘颗粒对翼型表面造成的磨损形貌预测及其气动性能的影响。结果表明:颗粒对翼型表面的冲蚀磨损区域主要集中在前缘
其磨损深度可达0.6%的弦长
随着攻角的增大
磨损区域在吸力面逐渐减小
而压力面呈扩张趋势;表面磨损的形貌使翼型前缘的压力出现波动
吸力面的流动分离现象显著提前
12°攻角时气流分离点向前移动距离可达31.43%的弦长;翼型表面受到冲蚀磨损后阻力系数上升
升力系数与升阻比下降
在12°攻角下
阻力系数上升44%
升力系数下降25%
升阻比下降48%;由此可见
表面磨损形貌降低了翼型的气动特性。
This study investigates the impact of sand-induced surface wear on the aerodynamic performance of the S809 wind turbine airfoil using a numerical approach integrating the Discrete Phase Model (DPM)
dynamic mesh
and Gaussian filtering. Results show that erosion is concentrated at the leading edge
with a maximum depth of 0.6% chord length. As the angle of attack increases (2°~12°)
the eroded region contracts on the suction side but expands on the pressure side. Surface wear causes pressure fluctuations at the leading edge and advances flow separation
shifting the separation point forward by up to 31.43% chord length at 12°. Erosion increases drag while reducing lift and aerodynamic efficiency
with a 44% drag rise
25% lift loss
and 48% decline in lift-to-drag ratio at 12°. These findings highlight the adverse effects of surface wear on airfoil aerodynamics.
