flammablem aterials fire accident tunnels prevention
For the f ire acc ident in the flammable materials transportation, tw o-phase-coup led Euler-i an-Lagrangian mode l and particle stochasticmodel are established, and a numerica l simulation of fire acc ident o f leakage of the truck filled w ith liquef ied propane in tunnel is conducted based on the componentm ixture fract ionmode.l The computed results g ive the d istribution of flow temperature in tunne .l A ccording to the theory of Safety System Engineering, fire caused by tw o-phase dispersion of propane re lease in the tunnel is studied, and the prevent ion measures are presented comb ining humanmach ine-env ironment theory, wh ich g ives theoritical basis o f predicting fire acc ident and d irecting urgency succor.
