摘要

为研究大型垂直轴风力机(VAWT)在不同并联布置间距时的功率提升情况

以及明确其在不同维度下尾迹流场的特性及差异

以大型三叶片H型VAWT为研究对象

通过计算流体动力学方法分析了不同维度下VAWT机组并联间距对其气动性能及流场特性的影响。结果表明:在相同布置间距下

二维与三维并联布置VAWT输出功率均有所提升

其中在间距1.50倍风轮直径时提升程度最大

但二维模拟所得功率提升程度显著大于三维;三维模拟时VAWT风轮内部流场特性较二维更复杂

单周期内叶片峰值产生小幅波动;此外

当并联布置间距过小时

VAWT机组之间的流体加速通道现象会被削弱

功率提升程度下降

三维涡管可视化图显示尾迹中的涡更难以消散

尾迹恢复需要更长的距离。

Abstract

To investigate the power enhancement of large vertical axis wind turbines (VAWT) under different parallel arrangement spacings

and clarify the characteristics and differences of their wake flow fields across various dimensions

a large three-bladed H-type VAWT was selected as the research subject. The influence of paralleled spacing on the aerodynamic performance and flow field characteristics of VAWT units was analyzed through computational fluid dynamics methods in different dimensions. Results show that under the same arrangement spacing

both two-dimensional (2D) and three-dimensional (3D) parallel arrangements of VAWT exhibit an increase in output power

with the maximum enhancement observed at a spacing of 1.50 times of the rotor diameter. However

the power improvement obtained from two-dimensional simulations is significantly greater than that from three-dimensional simulations. The internal flow field characteristics of the VAWT rotor in three-dimensional simulations are more complex than those in two-dimensional simulations

with slight fluctuations in blade peak values during a single cycle. Furthermore

when the paralleled arrangement spacing is too small

the phenomenon of fluid acceleration channels between the units will be weakened

and the power increase will decrease. The three-dimensional visualization of the vortex tubes shows that the vortices in the wake are more difficult to dissipate

and the wake recovery requires a longer distance.
