| Abstract: | For the fire accident in the flammable materials transportation, two-phase-coupled Eulerian-Lagrangian model and particle stochastic model are established, and a numerical simulation of fire accident of leakage of the truck filled with liquefied propane in tunnel is conducted based on the component mixture fraction model. The computed results give the distribution of flow temperature in tunnel. According to the theory of Safety System Engineering, fire caused by two-phase dispersion of pro- pane release in the tunnel is studied, and the prevention measures are presented combining humanmachine-environment theory, which gives theoritical basis of predicting fire accident and directing urgency succor. |
