摘要
采用标准k-ε模型,利用Fluent软件对典型单体建筑物绕流风环境进行数值模拟,并将其结果与Summer等人的实验数据进行了对比,分析了来流风速、迎风角以及建筑高度对风能特征的影响.以建筑物绕流风能的强化为目的,提出建筑物与风道相结合进行风能利用,并对其进行模拟分析.结果表明:迎风角对风能的可利用性影响较小,来流风速、建筑高度对风能的可利用性影响较大,建筑物与风道结合时风能的浓缩效果明显提高.
In this paper, the Fluent software was adopted to simulate the flow around the single typical buildings by means of the standard k-ε model. The computed results were compared to the data of Summer et al. Then the influence of the incoming wind velocity, the windward angle and the height of building on wind energy were analyzed respectively. The thinking of combination of building with channel was proposed to utilize wind energy, and the simulating analysis was conducted for strengthening wind energy. The results show that the windward angle has little effect on the availability of wind energy, but the incoming wind velocity and the height of building have great effects on the availability of wind energy. The concentration of wind energy is significantly improved by combining the building with the channel.
