亚运自行车馆气流组织CFD的分析和探讨

CFD Research on the Airflow of the Asian Games Velodrome

介绍亚运自行车馆的空调方案,高大空间-观众区和赛场的气流组织,在观众区顶侧部和赛场的顶部设了送风,在前四排座位底和最后一排座位平台侧面进行回风,排风设在场馆最顶部,使用了CFD软件对观众区和赛场进行了三维数值模拟,通过分析模拟的结果表明:观众区和赛场气流组织是满足设计要求的,温度、速度、PMV、PPD、空气龄均较为合适。

This paper introduced the air-conditioning program, the airflow of the audience area and the stadium of the Asian Games Velodrome. Air supply system was set up on the top of the audience area and the stadium, the air return system was set up at the bottom of the first four rows of seats and on the side of the platform, and the air exhaust system was set up on the top of the velodrome. Based on the CFD research on the airflow of the audience area and the stadium, it showed that the airflow of the audience area and the stadium was distribution to meet the design requirements, and temperature, speed, PMV, PPD and age of air were more appropriate.
