本文建立了一个适合建筑物绕流等环境流动的可压缩湍流粘性数值模型，并用该模型模拟了单个和多个建筑物的绕流，得出了建筑物问的滞留旋涡、建筑物“热岛”等对环境有很大影响的流谱．
This paper establishes a compressible turbulent viscosity numerical model suitable for flow around a building, and uses this model to simulate the flow around a single building and multiple buildings, and obtains the vortexes and “heat islands” of buildings. The flow spectrum that has a great impact on the environment.
