CFD modelling of fire development in metro carriages under different ventilation conditions

Fire development in a train carriage is investigated by CFD (Computational Fluid Dynamics) modelling. Two methods, i.e. the simple ignition model and the kinetic pyrolysis model, are applied. The model parameters are estimated and calibrated based on data obtained from small scale laboratory tests, including Thermo-Gravimetric Analysis (TGA) tests and cone calorimeter test carried out within the framework of the METRO project. Firstly, a full scale carriage fire test was simulated and the obtained results are compared with the test data. The comparison shows that both the simple ignition model and the kinetic pyrolysis model succeed to a large extent in predicting the fire development in the carriage. Further, the effects of ventilation and tunnel structure on fire development in carriages were investigated.
