The current study develops a transient combustion model formulated in oblate ellipsoidal coordinates to analyze the behavior of non-buoyant burner-generated diffusion flames. The combustion model is axially symmetric and considers a porous gas-fueled

Flame heat flux absorbed by a porous gas-fueled burner is measured in microgravity. The burner's perforated copper plate serves as a slug calorimeter in which two heat flux thermopile sensors are embedded. The slug calorimeter provides the average he

The Burning Rate Emulator (BRE) is a gas-fueled burner that emulates the burning of real condensed phase fuels. This is accomplished by matching four fundamental properties: heat of gasification, heat of combustion, surface vaporization temperature,

The objective of this study is to explore mechanisms for ignition and extinction for condensed-phase fuels via the use of a gas-fueled burner. Flames were generated with a porous 25 mm circular burner using mixtures of methane and propane with nitrog

Flame necking-in is a fundamental behavior at the base of diffusive pool fires caused by the entrained flow approaching the flame induced by buoyancy (density difference), which is also the major generation source of flame periodic oscillatory instab

This study presents the experimental procedure and results of highly controlled pool fire tests, in a quiescent environment, designed to accurately measure the fuel burning rate and, consequently for sufficiently large pools, the thermal radiation fl

Radiative heat transfer plays a crucial role in most fire hazard related combustion processes. The existing classic and modified mass transfer B-Numbers have deficiencies for some burning cases of fires because they do not involve external radiation

The paper addresses the basic combustion mechanism of buoyant turbulent diffusion flames with emphasis on flame generated turbulence. The vorticity equation and Kelvin's theorem show that the buoyant generation of vorticity and its dissipation within
