摘要：

The aim of this study is to quantitatively grasp effect of excess fuel gas on temperature distribution of fire plume ejected from an opening when the amount of combustible gas generated in compartment was changed. In this study, a series of a large-scale experiments were carried out. As the experimental conditions, the opening shape and the heat release rate of fire source were changed. By using the dimensionless value Z∗/Q ∗ef,w2/3 in consideration of excess fuel gas and temperature rise δTz, the temperature rise distribution could be nearly expressed by Eq.(15) as Z∗/Q ∗ef,w2/3 increases. © 2021 Architectural Institute of Japan.
