Book excerpt: Experimental testing of a mathematical model showed that radiant heat transfer accounted for no more than 40% of total heat flux required to maintain rate of spread. A reasonable prediction of spread was possible by assuming a horizontal convective heat transfer coefficient when certain fuel and flame characteristics were known. Fuel particle size had a linear relation to residence time of the flame while fuel bed porosity influenced burning rate. Burning regimes of liquid pool fires (turbulent, transitional, and laminar) appeared to also apply to moving fires in solid fuels.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Heat Transfer and Fire Spread The total heat flux related to fire spread was calculated for each set of test fires. These values are tabulated in table 2. The radiant heat fluxes reported by Thomas and Law (1965) are of the same magnitude where 0 and/or l were varied. This general agreement indicates radiant heat does contribute to rate of spread, but in the present case the energy is the combined sum of the heat transfer components. The next step was to determine how much heat was being supplied by the flame and how much by the combustion zone. Analysis of all the tests showed a nearly constant combustion zone temperature with no significant correlation to fuel moisture content.

Download or read book Fuel Particle Heat Exchange During Wildland Fire Spread written by Jack David Cohen and published by . This book was released on 2015 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: A wildland fire spreads when thermal energy heats up nearby fuel particles leading to their ignition. This heat transfer can only involve convection and radiation heat transfer. It is commonly assumed that radiation heat transfer is the dominant mechanism; that is, fire spread is primarily governed by radiation heat transfer. The purpose of this study was to quantity the contributions of convection and radiation prior to ignition and to test the assumption that radiation heat transfer is the dominant mechanism. The study used (a) mathematical modeling and (b) experimental methods. The mathematical model involved a two-dimensional, transient, finite-difference solution to the conduction heat equation using standard heat transfer equations. The mathematical model was not tuned to match the experimental data because the purpose of the model was to represent the physical processes. One set of experiments controlled fuel particle exposures to a radiant panel and another set of experiments had particles exposed to flame fronts during spreading fire. During the controlled experiments, irradiances were between 29.8 kW/m2 and 36.4 kW/m2. Fuel particles were cooled by free convection in some experiments and forced convection in others. All experimental fuel particles were fabricated from yellow poplar (Liriodendron tulipifera) and square in cross section. Particle sizes were 1, 3, 6, 9 and 12 mm for the controlled experiments and 1 and 12 mm for the fire spread experiments. The temperatures versus time plots predicted by the numerical model closely matched the shapes of the measured temperature profiles. Thus the mathematical model accurately captured the physics. Both experimental and numerical results from the controlled experiments showed that radiation heat transfer was not sufficient to ignite the 1 mm particle due to convective cooling. Experimental and numerical results from the fire spread experiments showed that convection (not radiation) was the dominant mechanism responsible for heating 1 mm particles to ignition for conditions relevant to wildland fires. These results indicate the need to consider both convective and radiative heat transfer at fuel particle scales in physical wildland fire spread models.

Book excerpt: Controlled fires are beneficial for the generation of heat and power while uncontrolled fires, like fire incidents and wildfires, are detrimental and can cause enormous material damage and human suffering. This edited book presents the state-of-the-art of modeling and numerical simulation of the important transport phenomena in fires. It describes how computational procedures can be used in analysis and design of fire protection and fire safety. Computational fluid dynamics, turbulence modeling, combustion, soot formation, thermal radiation modeling are demonstrated and applied to pool fires, flame spread, wildfires, fires in buildings and other examples.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding fire dynamics and combustion is essential in fire safety engineering and in fire science curricula. Engineers and students involved in fire protection, safety and investigation need to know and predict how fire behaves to be able to implement adequate safety measures and hazard analyses. Fire phenomena encompass everything about the scientific principles behind fire behavior. Combining the principles of chemistry, physics, heat and mass transfer, and fluid dynamics necessary to understand the fundamentals of fire phenomena, this book integrates the subject into a clear discipline: Covers thermochemistry including mixtures and chemical reactions; Introduces combustion to the fire protection student; Discusses premixed flames and spontaneous ignition; Presents conservation laws for control volumes, including the effects of fire; Describes the theoretical bases for empirical aspects of the subject of fire; Analyses ignition of liquids and the importance of evaporation including heat and mass transfer; Features the stages of fire in compartments, and the role of scale modeling in fire. Fundamentals of Fire Phenomena is an invaluable reference tool for practising engineers in any aspect of safety or forensic analysis. Fire safety officers, safety practitioners and safety consultants will also find it an excellent resource. In addition, this is a must-have book for senior engineering students and postgraduates studying fire protection and fire aspects of combustion.
