Behavior of Fire Plume Ejected from Opening with Soffit

Abstract

When a fire emerges inside a building, the windows break, flames and smoke eject outside, and there is a risk that the fire will spread to upper floors and neighboring buildings. Installing a soffit at the upper edge of any openings has been proposed as the first measure against spreading fire to upper floors. In this respect, the purpose of this research is to understand the quantitative aspects of a fire plume ejected through an opening by performing an experiment using a compartment model.
