中文摘要：
栈效果是为造自然通风的一个主导的驱动力。分析模型在柄为栈效果的评估被开发，为从柄内部边界的热转移的财务。两个都，有到有经常的边界温度的气流和的从边界的经常的热流动的条件被考虑。这些分析模型的预言能力被为假想的柄使用大旋涡模拟(LES ) 评估。结果证明也处于集体流动率，垂直温度侧面和压力差别在分析模型的预言和 LES 预言之间有相当好的协议。当上面的开始区域与更低的开始区域是相同的时，两个都，分析模型和 LES 的结果证明中立飞机能比柄高度的一一半高定位。进一步，比 KLOTE 模型在集体流动率预言做的，分析模型才更好表演。
英文摘要：
Stack effect is a dominant driving force for building natural ventilation. Analytical models were developed for the evaluation of stack effect in a shaft, accounting for the heat transfer from shaft interior boundaries. Both the conditions with constant heat flux from boundaries to the airflow and the ones with constant boundary temperature were considered. The prediction capabilities of these analytical models were evaluated by using large eddy simulation （LES） for a hypothetical shaft. The results show that there are fairly good agreements between the predictions of the analytical models and the LES predictions in mass flow rate, vertical temperatures profile and pressure difference as well. Both the results of analytical models and LES show that the neutral plane could locate higher than one half of the shaft height when the upper opening area is identical with the lower opening area. Further, it is also shown that the analytical models perform better than KLOTE＇s model does in the mass flow rate prediction.
