某住宅小区风环境优化设计
|
摘要
住宅小区作为城市中人们最重要的生活空间之一,它的舒适性与人们的生活质量息息相关,住宅小区风环境是城市居住空间品质和居民生态质量的重要评价指标.针对行列式、错列式、斜列式、点式4种典型的城市住宅小区布局形式,采用Sketchup软件建立96种不同参数的数值模型后通过计算流体力学软件进行了三维流场模拟,并以此为依据研究了建筑参数、气象参数、布局参数对典型城市住宅小区风环境的影响.
As one of the most important living spaces in the city,the comfort of residential community is closely related to the quality of people's life. The wind environment of residential community is an important evaluation index for the quality of urban living space and the ecological quality of residents. In the paper,according to the four typical layout forms of urban residential community which are determinant,stagger,oblique and point,96 numerical models with different parameters are established by Sketchup software,and three-dimensional flow field is simulated by computational fluid dynamics software. On the basis,the effects of building parameters,meteorological parameters and layout parameters on the wind environment of typical urban residential districts are studied.
