摘要
对天津地铁改扩建之后双层岛式站台下瓦房站进行了现场实测,并利用实测的边界条件对该站站台公共区通风空调系统气流组织进行了数值模拟与分析,得出现有气流组织方案已具有较好的空调效果。数值模拟软件CFD可用于地铁环控实际工程设计。本文同时给出了整个车站气流分布图,出入口及站厅与站台1.65m高度处温度场、速度场分布。
Field measurements were carried in Tianjin Xiawafang subway station with transverse uniform air-supply. Based on measured boundary conditions, simulation and analysis was made for the air-flow distribution of the communal zone. The results of numerical simulation are proved that the original airflow distribution has a satisfactory air-conditioning effect and the software CFD can be used in environment control system design in subway. The airflow distribution of station and temperature distributions, airflow field of entrance, 1.65m height of hall and platform are also presented in this paper.
