摘要:宅小区的平面布局对于小区内人行高度处的室外风环境有着重要的影响。通过对一个由12幢建筑物组成的建筑群，采用基于Reynolds时均化方程(RANS)和Renormalization group(RNG) k-ε湍流模型的数值模拟方法，得到小区的流场分布，以分析建筑群周围的风环境舒适性问题。改变相邻建筑物的左右距离和前后距离，比较不同布局下的风环境，获得了上述两个因素对于小区风环境的影响规律。
Abstract: The plan arrangement of residential quarters has a great effect on the outdoor pedestrian-level wind environment.In order to obtaining the velocity distribution around the buildings for the wind comfort analysis, numerical simulation Was carried out by using the Reynolds averaged equations and the RNG k-εturbuhnce model. These buildings were arranged by changing the x-direction or y-direction distance.On comparing the different plan arrangement simulation results, we can get the influence to the wind environment of the two elements stated above.
