摘要
建立复合式屏蔽门系统自然通风下的一维网络和三维动网格数值计算模型,通过对比分析,说明了一维方法用于车站换气特性研究的适用性;并计算了不同面积、纵向位置,个数以及存在其他风口时的屏蔽门风口的流动情况,分析了各个因素影响风口风量变化的原因。
In this paper numerical models for combined platform screen doors （CPSDs） based on one-dimensional network and three-dimensional dynamic mesh were constructed. Through the comparison of the numerical results, it is shown that the method of one-dimensional network is applicable to the investigation of station ventilation. Furthermore, different areas and longitudinal positions of CPSDs vents were studied as well as the influence of other vents, and factors affecting the airflow rate of vents were also analyzed.
