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.

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.
