| 摘 要： | 采用国际通用流体力学计算软件FLUENT,对无风门大功率射流巷道式通风方式进行了模拟仿真,并对锦屏交通辅助洞风机的布置设计进行了优化。通过计算比较隧道出口处的CO浓度、隧道内平均CO浓度及隧道内最高CO浓度三个浓度指标得出了横通道处射流风机布置的最佳方式。

| Abstract: | For the construction of Jinping auxiliary tunnel,valve-less high-power jet ventilation was simulated by use of the hydromechanical computation software of FLUENT,commonly used all over the world The layout of fans in the tunnel is also optimized.Based on the calculation and comparison of the CO concentration at tunnel outlet,the average CO concentration inside tunnel and the maximum CO concentration inside tunnel,the best layout scheme of jet fans in the transverse access is designed. |
