Turbulent Flame Spread on Vertical Corner Walls

摘要

In this study, attention is given to the corner fire spread mechanism and theflame spread behavior. Infrared (IR) radiometry and image analysis techniques have been developed in this study to measure flame spread rate on large areas with high resolution and frequency. In addition to the flame spread measurement, the fire-induced flow was studied by flow visualization, and the total incident heat flux to the wall surface from the flame was measured by Gardon-type heat flux meters. Based on these experimental studies, a thermal model for corner fire spread has been successfully developed.
