The role of secondary char oxidation in the transition from smoldering to flaming
The transition from forward smoldering to flaming in polyurethane foam is observed using indepth thermocouples and ultrasound probing. The experiments are conducted with small parallelepiped samples vertically placed in an upward wind tunnel. Three of the vertical sample sides are maintained at elevated temperature and the fourth is exposed to an upward oxidizer flow and a radiant heat flux. An...
متن کاملSome Observations of Two-dimensional Smoldering and the Transition to Flaming
Experiments have been conducted to study the upward smolder characteristics and the phenomenon of transition to flaming of a porous combustible material in the presence of an air/porous-solid interface. External air flow velocities ranging from 0 m/s to 2.5 m/s are forced upward and forward across the exposed, flat, vertical surface of a high void fraction, flexible, polyurethane foam to examin...
متن کاملControlling Mechanisms in the Transition from Smoldering to Flaming of Flexible Polyurethane Foam
Experiments have been conducted to study the controlling mechanisms involved in the transition from smoldering to flaming of a porous combustible material, flexible polyurethane foam, with an air flow forced across one of the porous-fuel surfaces. The experiments are performed in a small-scale, vertical, combustion wind tunnel, with the air flow forced upward and parallel to an exposed foam sur...
متن کاملAn insight into fluorescent transition metal complexes.
The emission from transition metal complexes is usually produced from triplet excited states. Owing to strong spin-orbit coupling (SOC), the fast conversion of singlet to triplet excited states via intersystem crossing (ISC) is facilitated. Hence, in transition metal complexes, emission from singlet excited states is not favoured. Nevertheless, a number of examples of transition metal complexes...
متن کاملClimate and Fuel Controls on North American Paleofires: Smoldering to Flaming in the Late-glacial-Holocene Transition
Smoldering and flaming fires, which emit different proportions of organic (OC) and black carbon (BC, in the form of char and soot), have long been recognized in modern wildfire observations but never in a paleo-record, and little is known about their interactions with climate. Here we show that in the late glacial-early Holocene transition period, when the climate was moist, relatively high qua...
