摘　　要：本文利用PHOENICS软件建立CFD模型,深度分析了一栋学校建筑的室内温度、空气流速和压力情况,并剖析了含有不同变量的案例。研究表明,建筑开口面积和通风烟囱会对空气流速和气压产生有利的影响,建筑设计以通过合理地增大开敞面积和烟囱高度来优化建筑的自然通风,从而实现建筑的节能以及改善室内空气质量。This paper established a CFD model with PHOENICS software and deeply analyzed the temperatures in doors, airflow speed and pressure distributions in a multi-storey building in a school and investigated a case containing different variables. The results showed that Opening area and ventilation window were advantageous for airflow and air pressure, theretbre the natural ventilation was improved by reasonable enlargement for opening area and smokestack height so as to realize the energy conservation and improve air quality in buildings.
