Strategy of Ventilation Efficiency and Pollution Toughness of High Density Typical Housing Module Based on CFD Simulation

摘要: 城市高密度住区越来越多，住区内部复杂的风环境将直接影响到居民的舒适程度。本项目聚焦城市高密度典型住宅，以天津市为例，利用CFD模拟技术对目标地区进行风环境评价，并以提升通风效率与承污韧性从而提升人体居住舒适度为目标探讨高密度典型居住区。利用CFD模拟技术，探索不同典型高密度住区模式的风–污环境时空分布特征，总结不同季节下不同组合模块的通风效率、承污耐受度与建筑布局形态的关系，为提出高密度住区通风效率与承污韧性的优化策略提供有力支撑。

Abstract: There are more and more high-density urban settlements, and the complex wind environment within the settlements will directly affect the comfort degree of the residents. The project focuses on urban high-density typical housing. Taking Tianjin as an example, CFD simulation technology is used to evaluate the wind environment in the target area, and discusses the high-density typical residential areas with the goal of improving ventilation efficiency and pollution bearing toughness and thus improving human residential comfort. Using CFD simulation technology, it is used to ex-plore the spatial and temporal distribution characteristics of wind-pollution environment in dif-ferent typical high-density residential modes, summarize the relationship between ventilation ef-ficiency, pollution tolerance and structure layout form of different combination modules in different seasons, and provide strong support for the optimization strategy of ventilation efficiency of high- density housing and pollution bearing toughness.
