- Abstract
- The establishment and characteristics of a two-layer, stably stratified environment in an enclosure due to a fire have been investigated in several experimental and analytical studies. A hot, essentially isothermal, layer lies over a relatively cooler, also closely isothermal, lower layer. The temperature levels and the heights of the zones vary as the fire grows. However, a quasi-steady approximation of this changing environment may be made in several circumstances. During this fire growth process, several penetrative flows arise in the enclosure. Among these are the ceiling-jet-driven wall flow, the buoyancy-induced flow adjacent to the wall and the fire plume itself, which arise in one zone and penetrate across the interface into the other zone where they may be positively or negatively buoyant. Penetrative convection generally refers to the latter circumstance, which is also the situation considered in the present work.
