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内和室外的空气品质。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分析 ,并将计算结果与实验数据进行了对比 ,二者吻合较好
The aerodynamic shadow zone is a swirling area formed by the wind field around the building. The presence of this zone affects the indoor and outdoor air quality. The three-dimensional K ε turbulence model is used to simulate the wind field around high-rise buildings. The calculated results are compared with the experimental data, and the two agree well
