建筑间行人高度处的风环境设计

Design of wind environment between buildings at pedestrian height

为使用简单的方法对居住区的风环境进行评价,采用CFD软件模拟,运用正交试验的方法选取模拟的工况.根据模拟的结果,推导出建筑尺寸、建筑间距与建筑通道间行人高度处最大风速比的函数关系式,并且进行实例验证.验证表明:该方法简单可行,对建筑师进行风环境设计具有较好的辅助作用.

In order to evaluate the wind environment of residential area with simple method.the CFD software was applied to carry out the simulation,and the orthogonal experiment method was used to select the conditions of the simulation.On the basis of simulation result,the function relation of building size and space to the maximum wind speed ratio at the height of pedestrian was derived and the experimental verification was conducted.It was shown by the verification that this method was simple and feasible,and had a better auxiliary function for the architectural engineers to perform the wind environment design.
