Smoke flow regularity in fire in underground railway stations

Establishing a CFD physical model based on the mathematical model of developing process of fire and smoke in underground railway, numerically simulates the train fire in island station without shield. Analyses the temperature and air flow distribution and smoke flow regularity, and compares the simulation results with the results of combustion experiments. The results show that CFD simulation result for fire is accurate enough if only the equation model is correctly selected and the boundary conditions are accurately set.
