In this paper it is shown how earlier results for buoyant vortex rings may be extended to describe the corresponding two-dimensional case, which arises in the theory of bent-over plumes. It is again assumed that in uniform surroundings the circulation remains constant while the…

In compartment fires a situation often develops in which a layer of oxygen-depleted gases builds up in the upper part of the enclosure. The downward reach of such a layer can be sufficient to make its lower boundary interact with the fire plume. In that case, while the…

To study mechanisms affecting particulate matter production from forest fires, a combustion chamber system was developed. This closed system was used primarily for producing cylindrical laminar diffusion flames by burning alpha-pinene under controlled conditions. The independent…

Although the burning of agricultural residues is not considered a net source of carbon dioxide because the carbon released to the atmosphere is reabsorbed during the next growing season, this burning is a source of net emissions of many trace gases including CH4, CO2, N2O, and…

A direct proportionality has been found between the smoke extinction area (SEA) for smoke of room linings and the SEA as measured in the cone calorimeter (ISO5660). The room test scenario (ISO9705) considered was the propane ignition burner at the corner with a 100/300 kW…

A high-resolution large-eddy simulation model is employed to examine the fundamental dynamics of buoyant plumes arising from heat sources representative of wildland fires in the presence of a vertically sheared ambient atmospheric crosswind. Time-averaged plume trajectories…

Smokes produced by burning pine litter, green needles, and fuels of lower nitrogen content were drawn through dilute acid solutions which were then nesslerized in the presence and absence of titanous sulfate. Kjeldahl analyses of fuels and residues indicated that 62% of the…

Smoke produced by vegetation fires consists of a complex mixture of gaseous, liquid, and solid phases. Many particulates are generated during vegetation fires. Crutzen and Andreae (1990) have estimated that global emissions of pyrogenic smoke particles (50-150 Tg yr-l) may…
