NUMERICAL SIMULATION OF FIRES IN VENTILATED COMPARTMENT

摘要

This study is the analytical investigation of transient flow characteristics in a ventilated compartment fire. This study aims at enhancing the understanding of tire 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 lhat. the fire field models based on CFD are useful tools that can greatly support this target.
