Transient Flame Behaviour in Underventilated Fires

摘要：

In the underventilated fire conditions, flames are featured by essential non-steadiness due to limited oxygen supply into the compartment. In some circumstances this can result in the emergence of open flames out of the ventilation openings (flame exhaust). In the earlier work, this transient behavior was studied in a fire box where the fire was modeled by a burner with a fixed fuel supply rate. This paper presents the results of recent experiments in which a pool of liquid fuel served as the fire source. Comparison of the results obtained clearly demonstrates that burner and pool fires behave somewhat differently in undervenilated conditions, which affects the time to flame exhaust and probability of flame extinction.
