An experimental study of smoke flow in tunnel fire

Yan Zhiguo1 Yang Qixin2 Zhu Hehua1(1.Tongji University,Shanghai 200092,China;2.Southwest Jiaotong University,Chengdu 610031,China)  
To investigate the behaviors of smoke when fire occurs in a tunnel,a series of fire tests were conducted in a large-scaled model tunnel.The scopes of the tests include smoke flowage,variation of smoke velocity with time and effect of forced ventilation on smoke flowage.The model tunnel is 100 m long,and it has a circular cross-section with an inner diameter of 1.8 m.An oil pool is employed as a fire source.Three levels of fire loads,categorized as A,B and C,are employed to simulate different fire scenarios.The results show that the smoke velocity at the fire point and in the area behind the fire point increases significantly from 2 min to 8 min after ignition.The increment of velocity varies with forced ventilation and fire load.The smoke velocity gradually decreases to the original value in the tunnel while fire attenuates.The results suggest that a longitudinal forced ventilation of 2~3 m/s should be established as soon as possible to prevent back-flow of hot smoke in case fire breaks out in a tunnel that prohibits tank trucks.
