The Smoke Exhausts Research on Urban Underground Fast Road

Abstract:

The aim of this research is to verify the effectiveness of smoke exhaust system including natural, longitudinal and semi-transverse system in urban underground fast road. For this research, a series of hot smoke tests were accomplished in experimental field in The Ministry of Transportation test site. The temperature distributions were recorded by thermocouples and the smoke flow laws were counted by visibility sensors. Meanwhile, the temperature distributions in the tunnel has been simulated by using the Computational Fluid Dynamics (CFD) software of ANSYS CFX. In terms of the experiments and simulation above, the smoke flow characteristics were demonstrated. Some valuable advices are given finally which can be applied to the design of smoke exhausted system in urban underground fast road.
