摘要
结合计算流体力学(CFD)软件中的FLUENT软件的应用,讨论促进城市街道峡谷汽车尾气污染物扩散的空间优化对策。以杭州市庆春路为实证,模拟并分析街谷中汽车尾气污染物分布特征与街谷空间形态的相关性,并进行空间优化设计试验。结果显示:以CFD数字模拟为基础的空间规划与设计策略可以积极的促进街谷内汽车尾气污染物的扩散和稀释。在公共安全与环境卫生问题日益显著的背景下,相关方法对城市规划设计的技术方法构成了积极的补充,并具有显著的实际效果。
Using the FLUENT model of CFD software, this paper explores the spatial optimization strategy to accelerate the diffusion of automobile exhaust pollutants in street canyons. Taking Qingchun Road of Hangzhou as an example, the paper simulates the distribution feature of automobile exhaust pollutants, analyzes its relation with the spatial form of street canyon, and conducts experiment on spatial optimization.The results show that the spatial planning and design based on CFD simulation can effectively accelerate the diffusion and dilution of automobile exhaust pollutants in street canyons. In the background of gradually noticeable public security and environmental sanitation problems, the relevant methods presented in this paper can enrich the technique of urban planning and design, and also have remarkable actual effects.
