中庭式住宅建筑热压通风的预测模型研究

为预测多因素耦合下中庭式住宅建筑热压通风的流场及温度场分布,采用网络模型和多区域模型结合的方法对住宅内部进行区域划分;根据质量、动量、能量守恒方程及伯努利方程,建立住户与中庭空间的热压通风气流环路预测模型.为验证该预测模型的准确性,根据阿基米德相似准则建立比例尺为1/25的实验模型,对比了中庭式住宅建筑热环境预测模型的计算结果与实验数据.结果表明,两者基本吻合,说明该模型能较精确地预测中庭式住宅建筑的热环境.

Prediction Model of Buoyancy-driven Ventilation in Residential Buildings with Atrium

In order to predict the buoyancy-driven flow and temperature fields influenced by coupling factors in residential buildings with atrium,the Multizone and Zonal methods were adopted to partition the building into zones.The prediction model of the loops between apartments and the atrium was established by means of mass,momentum,energy conservation equations.Furthermore,a reduce-scale model of 1/25,calculated by the similarity criteria of Archimedes number,was conducted to validate the accuracy of the predicti...
