Fire Compartment Upper-Layer Temperature Prediction Considering Excess Fuel Gas

Abstract

In this study, combustion experiments were conducted by changing the fire source conditions and opening conditions for excess fuel gas using a large-scale fire compartment. It was found that the occurrence of external flames depends on the opening factor A √H , surface area of the wall AT, and heat release rate (HRR) QC inside the fire compartment. Moreover, the larger the value of A √H in the experiment, the greater is the temperature rise in the compartment. McCaffrey's proposed temperature prediction model for the upper layer of the fire compartment was also modified and validated.
