摘　　要：本文利用计算流体力学技术,建立传统大学生宿舍物理和数学模型,对宿舍的通风状况进行模拟分析和实验验证。湍流模型采用室内零方程模型,速度压力解耦采用SIMPLE算法。采用德图testo435-635-735风速仪测量风速,验证模拟计算的准确性。在此基础上,进一步对夜间宿舍内的空气流动进行模拟分析,从而获得开窗的不同位置对整个宿舍内的空气龄分布的影响,以此分析夜间宿舍内的空气品质,并对夜间开窗位置提出一些建议。The physical and mathematic models were built up using the technology of the computational fluid dynamics, and the ventilation in the traditional student dormitory was studied by simulation and experiment. The turbulent model is indoor zero equation, and Semi-Implicit Method is for Pressure-Linked Equations. The simulation result is proved reasonable by the data from the testo435-635-735. The distributions of the mean air age in the dormitory were shown when the open window was at high and low locations. In the conclusion some advices about the open window location were given.
