摘要
本文采用标准RNGk-ε湍流模型对东莞市某住宅小区架空层设置方式对人行高度处风环境的影响进行了数值模拟,通过对4种不同架空方式的计算分析得出结论:首层架空后,人行高度处的流场平稳,无复杂涡流产生,风环境良好,对小区风环境改善效果明显。研究结果对住宅小区规划、建筑设计具有指导意义。
In this paper, with the RNG k-ε turbulence model, numerical simulation on the effects of aerial patterns in a residential community on head-level wind environment of pedestrian field was carried out. By simulating four different aerial patterns, the results indicated that aerial layer in the first floor could greatly improve the wind environment of pedestrian field, the flow filed was reasonable and there was no complex backsets. As a result, the references for residence communities＇ planning and building design were provided.
