Radiative transfer effects in natural convection above fires

This paper describes the results of examining the influence of radiative heat transfer on turbulent natural convection above fires in an atmosphere of constant potential temperature, under both the 'opaque' and 'transparent' approximations. It turns out that on the basis of the…

Fire whirlwinds in the laboratory

[Excerpted from text] Most experienced firefighters have encountered fire whirlwinds. These whirls, or "fire devils" as they are sometimes called, range in size from small twisters a foot or two in diameter up to violent whirls equal to small tornadoes in size and intensity.…

A study of field burning under varying environmental conditions

A field study on grass field burning was conducted in the Willamette Valley of Oregon during the summer of 1965. Approximately 230,000 acres of grass field are burned in the valley during August and September. Serious air pollution problems result from this burning. The purposes…
