摘要(Abstract):

为研究地铁站厅内的流通情况及温度分布规律,建立地铁站厅物理模型,结合能量守恒方程和流体动量方程进行流体模拟分析。设置不同的入口温度,通过对横向和纵向截面温度分布的分析,得到了地铁站厅内的温度分布规律。设置不同的入口风速,通过对横向和纵向截面气流组织的分析,得到了地铁站厅内的流场分布规律。研究结果为地铁站厅的空间优化和提高人体舒适率提供了参考。
In order to study the circulation and temperature distribution of subway station halls,a physical model of subway station hall was established to perform fluid simulation analysis in combination with energy conservation equation and fluid momentum equation. By setting different entrance temperatures and through analysis of temperature distribution in transverse and longitudinal sections,the temperature distribution in the subway station hall was obtained.By setting different entrance wind speeds and through analysis of airflow structures in transverse and longitudinal cross-section,the distribution of the flow field in the subway station hall was obtained.The research results provide a reference for space optimization and improvement of human comfort in subway station hall.
