From the text... 'An ideal forest fire detection system would detect fires the instant they start, day or night, under any condition of visibility. Additionally, it could distinguish potentially dangerous fires from those that would not concern fire suppression forces. Although…

From the summary:'Experimental study on the visibility through fire smoke was carried out. The relation among the brightness of sign, visual distance, and the extinction coefficient of smoke at the instant of obscuration threshold was obtained by using the smoke chamber. The…

From the text ' Under specific circumstances it has been shown that prescribed burning can be used: (1) to reduce fuel accumulation from logging and slashing and the hazard of accidental fire; (2) to prepare seedbeds and reduce competition for tree regeneration; (3) to improve…

Mass fires are being investigated through a series of large-scale test fires. Preliminary results indicate: (a) air flow patterns that create eddies can result in fire vortices when fires is present; (b) the lower part of the convection column consists of a series of small…

This paper reports a detailed laboratory study of two-dimensional starting plumes. From dimensional analysis, equations in a parametric form for the motion of two-dimensional starting plumes are derived. The governing equations are also obtained from an approximate inviscid flow…

The control of large fires is a problem of continuing concern to the Forest Service, other public agencies, and private owners of forest and rangeland. A few large fires each year account for all but a small share of the Nation's forest fire losses. In time of war, this problem…
