Examination of Spreading-Induced Changes in Fire Properties in Upper Layer of Compartment

Abstract

In this study, a large compartment was used and opening shapes were changed to set fire-source conditions and then combustion tests were conducted to quantitatively measure temperature and heat flux near a façade wall. In addition, <i>q</i> was inferred from the relationship between <i>z</i> and <i>q</i> for the top of the opening under different fire-source conditions and for various opening shapes so that <i>q</i> could be used as a reference index.
