空气动力阴影区是建筑物周围风场所形成的旋涡区域 ,该区域的存在会影响室外的空气品质。利用三维 k-ε紊流模型对高层建筑物周围风场进行了数值模拟 ,探讨了该区域的性质 ,同时将计算数值与实验数据进行对比 ,其结果符合很好。
The aerodynamic shadow zone is a swirling area formed by the wind field around the building and the presence of this zone affects the outdoor air quality. Three-dimensional k-ε turbulence model is used to simulate the wind field around high-rise buildings. The properties of this area are discussed. The numerical results are in good agreement with the experimental data.
