摘要
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．
A compressible turbulence model was presental to simulate numerically the air flow around buildings including the temperature effect. Some interesting results were obtained, such as : the detained vortices vortween buildings, separated flow patern, thermal effect of hot surface of building on the flow patern etc. These results are usefull to understand the environmental effect of air flow around buildings.
