摘　　要：采用CFD方法,对天津地区某生态办公建筑在过渡季节的建筑外表面压力分布进行了计算,并以压力入口为边界条件,数值模拟了建筑内各类房间的自然通风状况.计算结果表明,建筑外区具有两侧开口的房间室内通风状况良好,而对于外区单侧开口房间和内区房间,要充分利用建筑形态的凹凸变化、外开口距离、与通风走廊连通的内开口、通风夹道等的巧妙设计,创造通风房间有效开口压差,以达到在建筑内、外区都满意的自然通风效果.By using CFD method, this paper calculates the pressure distribution of the exterior surface of an ecological office building in the transition season, and then does a numerical simulation of the natural ventilation of various types of rooms in the building on the marginal condition of pressure inlets. The results show that among the exterior rooms with an opening on each of the two sides, those with only one opening on the exterior side, and the inner rooms, only the first type has good ventilation. For the latter two types, a satisfactory effect of natural ventilation in both the exterior and interior rooms can be achieved in the creation of effective pressure difference between openings by making full use of such ingenious designs as the concave and convex changes of architectural configuration, the distance between outside openings, the inside openings connecting to ventilation corridors, and ventilation walls, etc.
