摘要
针对具有一定内热源的庭院建筑,采用计算流体力学(CFD)方法,对庭院建筑热压作用下的自然通风进行数值模拟分析,通过改变室外温度场,得出了不同工况下建筑房间内通风量的分布情况及变化规律。结果表明:室内外温度差越大,房问的通风效果越好,且房间的热压通风效果随着建筑物高度的增加而变弱。该结论为庭院建筑自然通风系统的设计提供了理论依据。
Aimed at courtyard building with inside heating source, using the method of computational fluid dynamics （CFD）, changing the outside＇s temperature, and simulating the fluid field of the pressure natural ventilation, author presented the quantity of air ventilation and its changing rule in different fluid field; The result shows that The bigger difference between the indoor and the outside＇s temperature, the better efficiency of air ventilation, and the efficiency of thermal natural ventilation is decreasing with the height of the courtyard building increasing. All these conclusions provide theory foundation for the design of the natural ventilation system in courtyard building.
