摘要

该文通过三维计算流体力学方法对直叶片垂直轴风力机的支撑杆开展研究,对比分析4种不同支撑杆截面构型影响风力机叶片的流动机理。结果表明：支撑杆阻力特性与截面构型密切相关,其中圆柱形将导致风轮无法输出功率,而纺锤形支撑杆阻力性能相对最优,风轮总效率下降最少;支撑杆的直接阻力在相对风速较大的相位角时更加显著,而间接阻力主要影响垂直轴风力机叶片的吸力面。

Abstract

The strut is a necessary structure to connect the blades and transmit torque in vertical axis wind turbines, and it is also one of the main factors affecting the aerodynamic performance. Most studies have used simplified two-dimensional models, which cannot account for the influence of the strut on the aerodynamic performance of vertical axis wind turbine. Therefore, a study on the strut of a vertical axis wind turbine with straight blades using a three-dimensional computational fluid dynamics method is carried out, and the flow mechanisms of four different strut profiles affecting the blades of the wind turbine are analyzed. The results show that： the drag characteristics of the strut are closely related to its profiles. The cylindrical shape will result in the wind turbine being the unable to generate power, while the drag performance of the spindle-shaped strut is relatively optimal, causing the least decrease in total wind turbine efficency. The direct drag of the strut is more significant in the phase angle at higher relative wind speed, while the indirect drag mainly affects the suction surface of the blade of the vertical-axis wind turbine.
