Experimental Investigation and Numerical Simulation of Road Tunnel Fire
In order to investigate temperature distribution of the smoke flow in road tunnel fire and upgrade its fire safety, an experimental tunnel fare device was set up by the author. This model device, which was based on analogical theory, took an actual road tunnel located in Chengdu as rescarch object. The cross section of this model tunnel was 0.88mx0.5m, and its length was 10m. The wind speed in the tunnel could be adjusted between 0-5m/s. Using this device, a series of simulated experiments were carded out in order to get the temperature distribution rule, such as longitudinal distribution, transverse distribution and the scope of temperature pervasion. In this experiment, various ventilation velocities were set to simulate actual fire scene. The temperature of rue smoke was read by data collection system. Numerical simulation was carried out with FDS (Fire Dynamics Simulator). In general, the results of numerical simulation correspond with experiment data. The smoke scenes in tunnel with different ventilation velocities were also simulated with FDS. On the basis of experimental investigation and numerical simulation, some sound suggestions are put forward on control, rescue and personnel evacuation of tunnel fire.
