北京市通风廊道的模拟研究

摘要

随着我国城市化程度不断提高,很多城市都出现了比较严重的热岛效应、大气污染等.在国内外的许多案例中,通风廊道都是解决城市环境问题的主要手段之一,该文基于流体力学(CFD)技术,对北京市城市通风廊道进行分类、分级,针对不同类型的风道提出合理的规划建议.%With the continuous improvement of urbanization in our country, many cities have appeared some serious problems such as heat island effect, urban environmental pollution. Ventilation corridor is one of the main means to solve urban environmental problems in many cases at home and abroad. In this paper, starting from the perspective of the overall city planning macro, referencing cases related at home and abroad, and applying CFD technology, we will sort and grade the urban ventilation corridors in Beijing, and put forward some reasonable suggestions for different types of air ducts.
