高瓦斯隧道施工通风处理数值模拟分析
Numerical simulation for the ventilation in the construction of high gas tunnel
摘要
Abstract
The ventilation system is an important measure to eliminate gas disasters, the authors take the computational fluid dynamics software to simulate effective the ventilation treatment of the Zipingpu high gas tunnel. The simulation results show that from the view of reducing the gas concentration, 1 m/s wind speed can meet the ventilation requirements, 0. 5 m/s wind speed can basically meet the ventilation requirements, and 0. 2 m/s wind speed can not meet the ventilation requirements. Then using the numerical simulation method to determine the best method of ventilation, people can calculate a reasonable option on the ventilation, air volume and select the device.关键词
