| 摘 要： | 应用Fluent软件对长距离、大直径、采用双竖井送排式通风的隧道进行二维数值模拟,分别对隧道入口射流主风机及两组竖井送排风机进行测试,分析了5个风机转速的变化对隧道流场的改变情况。模拟结果表明,主风机的影响最大,竖并排风机的升压性能不如送风机。

| Abstract: | Presented the 2-dimensional simulation of a double-silo tunnel intake and exhaust ventilation mode by Fluent. Tested the tunnel-entrance main fan and two groups of the silo intake and exhaust fans, and analyzed the movement of the flow field when rotate speed for five fans change respectively. The simulation result indicates that the effect of the main fan is most great,and the pressure promotion capability of exhaust fan in silo is not as good as intake fan. |
