围合式高层住区空间布局的风模拟比较与优化——以长沙为例

The Wind Simulation and Optimization of Square-type High-rise Residential Area Space Layout:Taking Changsha as an Example

运用流体模拟计算软件Fluent对长沙地区典型的围合式高层住区实例进行风环境模拟,得出各住区总平面上通风现状中的优势与不足。根据围合式住区中各空间布局模式的通风潜力及可优化因素,首先从总平面开口方向着手调整实例一后进行二次对比模拟,验证得出较优化的住区开口方向,再从住区空间布局方面做实例二的比较模拟,得出较优化的空间布局方式,以期为长沙地区高层住区的绿色设计提供参考。

The wind environment simulation of the typical square-type high-rise residential areas in Changsha has been applied Fluent, a software that can convey a fluid simulation. By the end of the simulation, we summarize both the weaknesses and the advantages of the total plane of each residential area＇s airing conditions. During the simulation, we make some adjustments on example 1 and carry the second comparative simulation according to the airing potential and the optimized elements of the space placement in each residential area. Based on the result of the second simulation, we work out the better opening direction of the residential area, and thus carry the third comparative simulation with the example 2. As a result of the third simulation, we figure out the better space placement of the residential area, hoping that this survey can attribute references to the green design of Changsha＇s high-rise residential area.
