摘要

为揭示不同射流倾角的下击暴流风场特性及其对风力机叶片变形的影响

基于计算流体动力学方法模拟0°、5°、10°、15°、20°共5种射流倾角的大气边界层风场特性

分析不同射流倾角下击暴流的水平、垂向风速剖面

气压以及整体湍流强度分布

同时探究不同射流倾角风场对叶片表面压力分布以及结构变形量的影响。结果表明：射流倾角增大下击暴流发生一侧的水平风速最大值增加

垂向速度减小的速率变缓。倾角的改变对下击暴流发生区域气压的影响可忽略不计。对于湍流强度分布的影响

不同倾角下射流区背侧湍流强度均随射流倾角增大而增加而前侧则减小;风力机位于不同射流倾角的下击暴流风场中时

表面压力分布不均

叶尖较其他位置承受更大风压;射流倾角增大叶片表面压力随之增加

近地面两叶片压力大幅增加

在倾角为20°时达到最大

最大值约为50 Pa

远地面叶片表面压力增加缓慢。叶尖处结构变形量、叶片中段等效应力随倾角变大而增加。

Abstract

In order to reveal the wind field characteristics of downburst flow at different jet inclination angles and their effects on wind turbine blade deformation

this study simulated the wind field characteristics of atmospheric boundary layer at five jet inclination angles of 0°

5°

10°

15° and 20° based on computational fluid dynamics method

analyzed the horizontal and vertical wind velocity profiles of downburst flow at different jet inclination angles. Meanwhile

the influence of wind field with different jet inclination angles on blade surface pressure distribution and structural deformation is explored. The results show that with the increase of jet inclination

the maximum horizontal wind speed on the side where the downburst occurs increases

and the rate of vertical velocity decreasing slows down. The change of inclination angle has anegligible effect on the pressure in the area where the downburst occurs. For the influence of turbulence intensity distribution

the turbulence intensity at the back of the jet region increases with the increase of jet inclination

while the turbulence intensity at the front side decreases. When the wind turbine is located in the downburst flow field with different jet inclination angles

the distribution of blade surface pressure is inhomogeneous

and the blade tip bears more wind pressure than other positions. With the increase of jet inclination angle

the blade surface pressure increases

the pressure of the near-ground two blades increases substantially

reaching the maximum value of about 50 Pa when the inclination is 20°. The pressure of the father-from-ground blade surface increases slowly. The structural deformation at blade tip and the equivalent stress in the middle of blade increase with the increase of the inclination angle. This study provides some theoretical support for the safe operation of wind turbines in extreme weather

also offers assistance for wind turbine anti-wind design.
