摘要
应用计算流体力学Fluent软件,对围绕屋面光伏阵列的风场进行雷诺平均数值模拟。首先通过与已有的风洞试验研究结果进行对比,验证两种雷诺平均模型RNG k-ε和SST k-ω计算屋面光伏阵列风场的可靠性。然后,以20°风向角为间隔,对0°-180°范围的10个风向角分别进行了风场模拟,并得到了已有风洞试验结果的验证。再选取2°和20°两种光伏板倾角,分析它们对屋面光伏阵列风场的影响。最后,在不同光伏板倾角的情况下,分析了0.09,0.41,1.02 m三种光伏板与屋面的间距对光伏板表面风压场的影响。
The wind field around photovoltaic（PV） array mounted on building roofs was simulated numerically by Reynolds-Averaged Navier-Stokes（RANS） approach using the software Fluent. Firstly,the reliability of both RANS models（RNG k-ε and SST k-ω） for calculating the wind field of PV array on roofs was validated through comparison with the results from other researcher＇s wind tunnel experiments. Secondly,the numerical simulation of wind field at ten angles wind direction from 0° to 180° in interval 20° was carried out and verified by other researcher＇s wind tunnel experimental results. Then,two inclination angles of PV panel,2° and 20°,were selected and their influences on flow field were investigated. Finally,the effects of clearances,0. 09 m,0. 41 m and 1. 02 m,between PV panel and roof on wind pressure field around PV panels were studied at the different inclination angles of PV panel.
