浙北筒屋式民居夏季自然通风数值模拟

Simulation Study on Summer Natural Ventilation of a Tubular House in Northern Zhejiang Province

为完善对浙北筒屋式民居夏季自然通风状况的认识,并为绿色建筑通风设计提供参考依据,文章以湖州德清一筒屋单体为对象,采用CFD方法对室内外风场分布进行仿真,研究筒屋周边大气的压力场及速度场分布以及筒屋的空间组合及通廊、天井等细部对室内自然通风的影响,分析比较不同工况下的通风情况。

In order to investigate the natural ventilation of the tabular house and provide technical references for green building ventilation design,this paper simulates indoor and outdoor wind field distribution in two cases using the CFD technique,with a single tabular house in Huzhou as the research object.Research include the distribution of atmospheric pressure field and velocity field around the tubular house,as well as the influence of the spatial combination of tubular houses and the details such as corridors and courtyards on the indoor natural ventilation.
