Abstract

Summary: This paper measured and analyzed the vertical temperature profile of window ejected fire from a cubic enclosure with the effect of adjacent parallel sidewalls. A cubic enclosure size is 0.4 m (height) × 0.4 m (width) × 0.4 m (length). And two side walls were fixed on the both side of the compartment openings, its distance can be changed. K‐Type thermocouples (T1 ‐T4 ) were installed in the inside compartment (inner and outer corner), the vertical position along the façade wall and the center of side wall, respectively. It is found that the side wall distance was independent of the temperature distribution inside the enclosure when the opening size changed from 0.2 m to infinity, and the vertical temperature profile along the side wall significantly increased with the decrease of the separation distances of two sidewalls. A dimensionless correlation was proposed to describe the vertical temperature along the facade wall for various side wall separation dimensions. The new findings and the proposed dimensionless correlation provide basic knowledge for describing vertical temperature along the facade wall.
