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…

In 1970, it was widely assumed that by 1980 in the Pacific Northwest, prescribed fire would be a thing of the past. By 1985, however, half way from 1970 to the end of the century, the area treated by fire increased. Now, the demise of forest burning is widely expected to occur…

We have used the high optical absorptivity of urban and source particulates to trace their ‘graphitic” component. The optical absorptivity and the particu late carbon loading show a strong correlation. Analyses of the data indicate that primary soot emissions compose a major…

Flexible polyurethane foams that are char formers are capable of smoldering combustion. The smoldering process is an oxygen-limited, heterogenous oxidation process that slowly transforms the foam to a brittle, black replica of itself; for the foam examined here, the resultant…
