摘要/Abstract

摘要：

采用开源计算流体力学软件OpenFOAM中的Simple求解器对流场进行数值模拟，研究5.00 m/s风速下槽式太阳能阵列挡风墙挡风效果。对由槽式太阳能阵列组成的6个不同高度的挡风墙对整体流场速度的影响以及不同高度挡风墙背风侧30，60，90 m处的速度进行了分析。研究发现，当气流通过挡风墙时，低于墙高的位置速度大幅衰减，而高于墙高的位置开始加速，存在明显的分区作用。当气流流过挡风墙后，会在其后形成明显的速度衰减区，其面积和延伸与挡风墙的高度正相关。在挡风墙背风侧较远处，高于墙高的气流开始减速，低于墙高的气流开始加速，并随着距离的增加风速逐渐趋于平稳。

Abstract:

Taking the Simple solver of the open source computational fluid dynamics （CFD） software， OpenFOAM， to numerically simulate a flow field， the wind blocking effect of a windbreak under a wind speed of 5.00 m/s is studied. The windbreak is composed of trough solar arrays. The effects of the barrier at six different heights and with three different distances （30， 60， and 90 m） from its leeward side to the flow field on the overall velocity of the flow field are analyzed. It is found that there is obvious partitioning in the blocking effect. When the airflow passes through the windbreak wall， the flow velocity attenuates significantly at a position lower than the height of the wall， and it accelerates at a position higher than the wall. There is a velocity attenuation area behind the wall， whose size is highly positively correlated with the height and distance of the wall. When the distance of the leeward side gets farther， the flow velocity at a position higher than the wall gets slower and that at a position lower than the wall gets faster. The wind velocity gets stable with the extension of the distance from the leeward side to the flow field.

Key words: trough solar array, windbreak, wind blocking effect, velocity attenuation area, OpenFOAM, numerical simulation
