摘    要:利用CFD-GIS技术对复杂地形下人行高度处风场和压力场进行城市尺度对比分析,且对规划区风环境进行分区。并以城市尺度模拟下的数据,单向向下嵌套对单个住宅区朝向进行住宅区尺度模拟分析,得出最佳方案,为规划师提供量化数据支持。

Abstract:

Based on CFD-GIS technology, a comparative analysis is carried out for wind and pressure field at pedestrian level in a complex terrain in urban scale, and the planning region is divided into different wind environment areas. Using the data simulated in urban scale models as the boundary condition, different buildings towards residence scale models are analysed by the one-way downward nesting system. And the optimal scheme is obtained. These can help planner to make decision based on the quantitive data.
