Simulation Time

Subway plays an important role in urban transport system. Fire as the major risk of the subway, is gaining increasing concern. In this study, fire simulation is performed to estimate fire safety of different compartments of the subway train. Result shows that the two compartments in the middle become dangerous at 150s and the compartments in the two ends are not safe at 300s approximately. The other two compartments are always safe during the simulation time.

Fifteen numerical simulations are presented in this article to investigate the influence of roof opening size and fire source size on gas temperature profiles in a compartment. The fire source size has a significant impact on the temperature hot smoke layer. The temperature of hot smoke layer increases as the increase of fire source size. The roof opening has cooling function to gas temperature in the compartment especially for large roof opening. The temperatures of hot smoke layer decrease with the roof opening size increase in all cases.

This study is the analytical investigation of transient flow characteristics in a ventilated compartment fire. This study aims at enhancing the understanding of fire propagation in the compartment and its influence on the air flow characteristics. The present paper discusses the results of different ventilation scenarios for a single fire scenario. It is recommended to use the smoke extract fans in designated locations in the spaces that could be exposed to the fire hazards. Corridor smoke extract fan provides the safe escape for the occupancy. Quantitative parametric studies are carried out for various situations, to enhance our knowledge about the fire behavior. The critical time for the safe escaping of occupancy from the fire starting is discussed in the present work. Also, it is found that, the fire field models based on CFD are useful tools that can greatly support this target.
