摘要
在１∶２５０的风洞模型上，测量街道峡谷的平均流速、湍流度等参数，分析了街道峡谷内的湍流流动状态，探讨了屋顶来流风在街道峡谷内产生复杂流场的主要特征，并用三维湍流模型对风洞试验模型进行了数值计算，试验和计算结果为研究街道峡谷风环境以及街道峡谷的传热传质过程提供了基础。
Both wind tunnel test investigation and numerical modeling on the same scaled street canyon models is reported.The relationship between the flows within the canyons and above the rooftops is discussed.The results bring us a better understanding on the process of the heat and mass transfer in the urban street as well as the wind effect of street canyon.
