Download or read book Sensitivity of Fire Behavior Simulations to Fuel Model Variations written by Lucy Anne Salazar and published by . This book was released on 1985 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stylized fuel models, or numerical descriptions of fuel arrays, are used as inputs to fire behavior simulation models. These fuel models are often chosen on the basis of generalized fuel descriptions, which are related to field observations. Site-specific observations of fuels or fire behavior in the field are not readily available or necessary for most fire management planning situations. Fuels are thought of in general terms and a single fuel model is often assigned to represent large areas of land. Variations in weather, which can substantially affect fire behavior, are not reflected in the available aids for selecting fuel models. The sensitivity of simulated fire behavior variables to the 13 fire behavior fuel models and two-fuel-model alternatives was analyzed. The two-fuel-model concept demonstrated the effect of combining fuel models on simulated fire behavior results.

Download or read book Fire Behavior in Nonuniform Fuels Classic Reprint written by William H. Frandsen and published by Forgotten Books. This book was released on 2018-09-11 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Fire Behavior in Nonuniform Fuels For the purposes of this study nonuniform fire behavior is predicted by modeling fire Spread through a hexagonal network of fuel cells. Fire spread is assumed to be a process of contagious growth between cells. Fuel properties are allowed to vary from cell to cell in a prescribed manner but have uniform properties within the cell. Consequently, the nonuniformity of the actual fuel array is simulated through cell to cell variations and has a resolution limited by the cell size. Because of the nature of the modeling process it is necessary to devise a scheme for collect ing data describing nonuniformity and a scheme for filling the hexagonal cell array in a manner that-simulates the actual fuel nonuniformity.

This book was released on 2018-08-12 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Fuel Burning Rates of Downward Versus Horizontally Spreading Fires The method of obtaining w experimentally has been covered by Frandsen and Rothermel (1972) in their investigation of the reaction intensity of the combustion zone of a Spreading fire. (the rate w is properly a loss; however, the negative sense is inter nally compensated.) The reaction intensity, ir, is another important dynamic parameter of the fire. It is the total energy-release rate evolved from the combustion zone, and is related to w through h, the low heat of combustion.

This book was released on 2017-11-18 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Model for Predicting Lightning Fire Ignition in Wildland Fuels This report, the second of several planned on the topic of lightning-caused fires (see Preface), describes the development and structure of a model for predicting the ignition of Wildland fuels by lightning. The model is both physical and stochastic in structure. The physical processes for ignition of fine woody fuels by lightning are the basis for the model. Stochastic processes are used to generalize site conditions for a large area and the chance occurrence of simultaneous events required for ignition.

Download or read book Wildland Fire Behaviour written by Mark A. Finney and published by CSIRO PUBLISHING. This book was released on 2021-11-01 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildland fires have an irreplaceable role in sustaining many of our forests, shrublands and grasslands. They can be used as controlled burns or occur as free-burning wildfires, and can sometimes be dangerous and destructive to fauna, human communities and natural resources. Through scientific understanding of their behaviour, we can develop the tools to reliably use and manage fires across landscapes in ways that are compatible with the constraints of modern society while benefiting the ecosystems. The science of wildland fire is incomplete, however. Even the simplest fire behaviours – how fast they spread, how long they burn and how large they get – arise from a dynamical system of physical processes interacting in unexplored ways with heterogeneous biological, ecological and meteorological factors across many scales of time and space. The physics of heat transfer, combustion and ignition, for example, operate in all fires at millimetre and millisecond scales but wildfires can become conflagrations that burn for months and exceed millions of hectares. Wildland Fire Behaviour: Dynamics, Principles and Processes examines what is known and unknown about wildfire behaviours. The authors introduce fire as a dynamical system along with traditional steady-state concepts. They then break down the system into its primary physical components, describe how they depend upon environmental factors, and explore system dynamics by constructing and exercising a nonlinear model. The limits of modelling and knowledge are discussed throughout but emphasised by review of large fire behaviours. Advancing knowledge of fire behaviours will require a multidisciplinary approach and rely on quality measurements from experimental research, as covered in the final chapters.
Download or read book Assessing Crown Fire Potential by Linking Models of Surface and Crown Fire Behavior written by Joe H. Scott and published by . This book was released on 2001 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire managers are increasingly concerned about the threat of crown fires, yet only now are quantitative methods for assessing crown fire hazard being developed. Links among existing mathematical models of fire behavior are used to develop two indices of crown fire hazard-the Torching Index and Crowning Index. These indices can be used to ordinate different forest stands by their relative susceptibility to crown fire and to compare the effectiveness of crown fire mitigation treatments. The coupled model was used to simulate the wide range of fire behavior possible in a forest stand, from a low-intensity surface fire to a high-intensity active crown fire, for the purpose of comparing potential fire behavior. The hazard indices and behavior simulations incorporate the effects of surface fuel characteristics, dead and live fuel moistures (surface and crown), slope steepness, canopy base height, canopy bulk density, and wind reduction by the canopy. Example simulations are for western Montana Pinus ponderosa and Pinus contorta stands. Although some of the models presented here have had limited testing or restricted geographic applicability, the concepts will apply to models for other regions and new models with greater geographic applicability.

Download or read book A Gallery of Combustion and Fire written by Charles E. Baukal, Jr. and published by Cambridge University Press. This book was released on 2020-09-03 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Gallery of Combustion and Fire is the first book to provide a graphical perspective of the extremely visual phenomenon of combustion in full color. It is designed primarily to be used in parallel with, and supplement existing combustion textbooks that are usually in black and white, making it a challenge to visualize such a graphic phenomenon. Each image includes a description of how it was generated, which is detailed enough for the expert but simple enough for the novice. Processes range from small scale academic flames up to full scale industrial flames under a wide range of conditions such as low and normal gravity, atmospheric to high pressures, actual and simulated flames, and controlled and uncontrolled flames. Containing over 500 color images, with over 230 contributors from over 75 organizations, this volume is a valuable asset for experts and novices alike.
