Synopsis
Excerpt from Potential Spotting Distance From Wind-Driven Surface Fires
A model is presented here for intermediate-range spotting in which a spreading surface fire, idealized as a straight line perpendicular to the direction of the wind, provides the source of buoyancy that lofts firebrand particles above the ground for transport downwind. Short — range spotting of a few tens of meters from fires of low intensity is not addressed. Also not addressed is the very long-range spotting of tens of kilometers associated with severe fire phenomena such as the establishment of fire whirls or sustained spread of fire through the crowns of timber stands. These unique phenomena require separate treatments. Not considered in this model is the probability that there exists a firebrand particle in the fuel complex that has the particular size that will permit it to be a maximum-distance spot fire source. Particles that are too small can be lofted to a greater height than that of the maximum — distance particle, but they will burn out before returning to the ground. Larger particles cannot be lofted so high, and thus will not travel as far. The probability of ignition by a firebrand particle is also not addressed in this paper. What is predicted is the distance to which a viable firebrand could be carried. If it fails to land upon a suitable fuel to ignite, or if the fire ignited fails to spread, no spot fire will occur.

Potential Spotting Distance From Wind-Driven Surface Fires (Classic Reprint)
impression à la demandeVendeur : Forgotten Books, London, Royaume-Uni
Évaluation du vendeur 4 sur 5 étoiles
Paperback. Etat : New. Print on Demand. This book examines the spread of wildland fires, using a mathematical model to predict the distance over which spotting can be expected ahead of a fire front. The model is based on the work of previous authors and extends it to include the lofting of firebrands by large, steady, isolated flames such as those from the burning of heavy fuel accumulations. The model and its extensions have been coded as algorithms for pocket calculators for easy field application, and provides a valuable aid to tactical fire suppression planning. This book provides a well-marked trail through the analytical thicket of the model to help in finding and fixing the flaws it probably includes so that future research can trace such defects to their sources within the model so they can be corrected. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. N° de réf. du vendeur 9781528326124_0
