摘要

该文利用流体力学模拟计算软件Ansys Fluent

基于标准k-ε湍流模型

对不同风向角及安装倾角条件下光伏阵列表面静压力分布规律及其风压系数展开研究。结果表明：首排光伏组件对角度变化敏感

其垂直向下压力载荷随安装倾角增大显著上升。后排光伏组件因前排遮蔽效应

表面静压力波动较小

第3、4排呈现流场稳定化特征。阵列下表面吸力效应由绕流低压主导

随风向角增加整体吸力系数上升

但第2、3排因气流分离与再附着作用局部吸力阶段性减弱

形成“首排主导-2排过渡-后排稳定”的3段式分布。

Abstract

The computational fluid dynamics software ANSYS Fluent

based on the Standard -ε turbulence model

is employed to investigate the distribution of surface wind pressure and the aerodynamic shape coefficients of photovoltaic （PV） arrays under varying wind incidence and installation angles. The results illustrate that the front-row PV modules are highly sensitive to angle variations. The downward vertical pressure loads are significantly increased with the installation tilt angle. Due to the shielding effect of the front row

low surface pressure fluctuations are observed on the downstream modules. Flow-field stabilization characteristics are exhibited in the third and fourth rows. The suction effect on the lower surface of the array is dominated by low pressure induced by the flow around the array

and an overall increase in suction coefficient appears with increasing wind incidence angle. Nevertheless

owing to the effects of flow separation and reattachment

a stagewise reduction in local suction is identified in the second and third rows

forming a three-stage distribution pattern characterized as ‘front-row dominant

second-row transitional

and rear-row stabilized’.
