Dynamic Numerical Simulation of the Tunnel Fire Process

ZHANG Guang-peng,LEI Bo(National Traction Power Key Laboratory,Southwest Jiaotong University,Chengdu 610031,China)  
In order to study the situation of tunnel smog and temperature after the fire in Tunnel,this paper established a fire model for calculating air temperature,the temperature of cliff side and calculating the concentration of fire smog in the tunnel with the fire principle of the underground project.Also,the calculation procedure of emulation has been worked out.Above-mentioned model and fire smog concentration with the time in different location had been simulated when the fire takes place in different positions,the requirement of ventilation without the backset current of exhaust gas was obtained for the fire in different positions of the tunnel.At last,the situation that the jet fans were damaged by the high-temperature exhaust gas is analyzed.
