摘要
利用STACH－3软件对8种不同通风方式进行数值模拟，得到实验小室的速度场和空气年龄场，将模拟计算结果与示踪气体实验结果进行了对比，并对典型工况的室内空气流动进行了分析。结果表明，STACH－3软件计算通风房间的空气年龄可靠性较高，可用于分析房间的通风效率。
The velocity field and air age distributions for 8 cases in a mechanically venti-lated test chamber are simulated with STACH - 3 software. The predicted air age distributionswere compared with the experimental ones with tracer gas technique and the typical flow patternwas analyzed. It is shown that STAHC - 3 can predict air age distributions with agreeable re-sults and can be used for the analysis of ventilation effectiveness.
