Abstract
In a typical compartment fire, two clearly distinguishable layers of hot gases on the top of cold gases are formed with a relatively steep vertical gradient of temperature and composition separating them. A burning vertical wall in the compartment can be strongly affected by the stratification of the interior atmosphere because the wall fire flow is a strongly buoyant natural convection flow, and the buoyancy force itself depends on the difference of temperatures between the fire plume and the outside atmosphere. In this paper, we investigate the effect of the stratification of the ambient atmosphere inside the compartment, as compared to the extensively studied problem of a vertical wall fire in a uniform (nonstratified) atmosphere.
