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…

[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.…

Late in 1961 the Northern Forest Fire Laboratory initiated a fire detection research program. The primary objective of this program is the development of a system capable of detecting both man-caused and lightning-caused fires day or night through all normally encountered…
