摘要
本文针对某大型复杂山地小区的风环境进行了数值仿真,并用计算流体力学的方法求解了夏季和冬季的稳态三维流场。分析了各建筑间的巷道风、污染物浓度、行人高度处的来流风速,以及在风压作用下建筑的迎风面和背风面的压力差等,得出了对以后山地小区风环境的模拟及合理的规划具有参考价值的结果。
Aiming at the wind environment for a large mountain area of the numerical simulation.Solves the steady-state three-dimensional flow field in the summer and winter by CFD. Analyses the roadway wind, pollutant concentration,wind velocity of pedestrian height between the buildings, and the pressure difference in the windward and leeward of the buildings under wind pressure,etc.It has reference value for simulating wind environment and reasonable planning of residential quarters.
