摘要

风电叶片结冰后会导致风能利用系数降低以及加快组件疲劳

基于此采用数值模拟方法对NACA4415翼型进行了气动特性的研究

分析不同来流风速下

翼型结冰后升阻力系数的变化规律以及周围的流场分布情况。随着结冰时间的增加

升力系数逐渐减小随后趋于稳定

阻力系数增加但中间有波动。采用压电振动法对翼型开展了除冰的仿真研究

通过谐响应分析压电元件厚度以及间距对除冰效果的影响

确定最优压电元件厚度和间距分别为0.5 mm和3.0 mm。通过热分析计算温度、弹性应力及弹性应变的变化规律

随着结冰时间的不断延长

结冰体的平均温度呈指数升高

致使覆冰的弹性应力和弹性应变近似线性增加。

Abstract

The icing of wind turbine blades can result in decreased wind energy utilization coefficients and accelerated component fatigue. Based on this

this paper conducts a study on the aerodynamic characteristics of the NACA4415 airfoil using numerical simulation methods. Variation of lift and drag coefficient and the distribution of surrounding flow field after the wing profile icing under different incoming wind speeds are analyzed. As icing time increases

the lift coefficient gradually decreases and then stabilizes

while the drag coefficient increases with intermittent fluctuations. Furthermore

a simulation study on de-icing of the airfoil is conducted using the piezoelectric vibration method. Through harmonic response analysis

the influence of piezoelectric element thickness and spacing on de-icing effectiveness is evaluated

resulting in the optimal piezoelectric element thickness and spacing being determined as 0.5 mm and 3.0 mm

respectively. Thermal analysis is also performed to calculate the changes in temperature

elastic stress

and elastic strain. As icing time extends

the average temperature of the ice mass increases exponentially

leading to an approximately linear increase in the elastic stress and elastic strain of the ice coverage.
