Module III – Fire Analysis Fire Fundamentals: Definitions
Module III – Fire Analysis Fire Fundamentals: Definitions Joint EPRI/NRC-RES Fire PRA Workshop August 21-25, 2017 A Collaboration of the Electric Power Research Institute (EPRI) & U.S. NRC Office of Nuclear Regulatory Research (RES) What is a Fire? .Fire: – destructive burning as manifested by any or all of the following: light, flame, heat, smoke (ASTM E176) – the rapid oxidation of a material in the chemical process of combustion, releasing heat, light, and various reaction products. (National Wildfire Coordinating Group) – the phenomenon of combustion manifested in light, flame, and heat (Merriam-Webster) – Combustion is an exothermic, self-sustaining reaction involving a solid, liquid, and/or gas-phase fuel (NFPA FP Handbook) 2 What is a Fire? . Fire Triangle – hasn’t change much… . Fire requires presence of: – Material that can burn (fuel) – Oxygen (generally from air) – Energy (initial ignition source and sustaining thermal feedback) . Ignition source can be a spark, short in an electrical device, welder’s torch, cutting slag, hot pipe, hot manifold, cigarette, … 3 Materials that May Burn .Materials that can burn are generally categorized by: – Ease of ignition (ignition temperature or flash point) . Flammable materials are relatively easy to ignite, lower flash point (e.g., gasoline) . Combustible materials burn but are more difficult to ignite, higher flash point, more energy needed(e.g., wood, diesel fuel) . Non-Combustible materials will not burn under normal conditions (e.g., granite, silica…) – State of the fuel . Solid (wood, electrical cable insulation) . Liquid (diesel fuel) . Gaseous (hydrogen) 4 Combustion Process .Combustion process involves . – An ignition source comes into contact and heats up the material – Material vaporizes and mixes up with the oxygen in the air and ignites – Exothermic reaction generates additional energy that heats the material, that vaporizes more, that reacts with the air, etc. -
Fire-Modified Meteorology in a Coupled Fire–Atmosphere Model
704 JOURNAL OF APPLIED METEOROLOGY AND CLIMATOLOGY VOLUME 54 Fire-Modified Meteorology in a Coupled Fire–Atmosphere Model MIKA PEACE Bushfire Cooperative Research Centre, Melbourne, Victoria, and Applied Mathematics, Adelaide University, and Bureau of Meteorology, Adelaide, South Australia, Australia TRENT MATTNER AND GRAHAM MILLS Applied Mathematics, Adelaide University, South Australia, Australia JEFFREY KEPERT Bureau of Meteorology, Adelaide, South Australia, and Bushfire Cooperative Research Centre, Melbourne, Victoria, Australia LACHLAN MCCAW Department of Parks and Wildlife, Manjimup, Western Australia, Australia (Manuscript received 19 March 2014, in final form 27 November 2014) ABSTRACT The coupled fire–atmosphere model consisting of the Weather and Forecasting (WRF) Model coupled with the fire-spread model (SFIRE) module has been used to simulate a bushfire at D’Estrees Bay on Kangaroo Island, South Australia, in December 2007. Initial conditions for the simulations were provided by two global analyses: the GFS operational analysis and ERA-Interim. For each NWP initialization, the simulations were run with and without feedback from the fire to the atmospheric model. The focus of this study was examining how the energy fluxes from the simulated fire modified the local meteorological environment. With feedback enabled, the propagation speed of the sea-breeze frontal line was faster and vertical motion in the frontal zone was enhanced. For one of the initial conditions with feedback on, a vortex developed adjacent to the head fire and remained present for over 5 h of simulation time. The vortex was not present without fire–atmosphere feedback. The results show that the energy fluxes released by a fire can effect significant changes on the surrounding mesoscale atmosphere. -

ABSTRACT This Paper Outlines the Subject Matter of Research
Invited Lecture An Overview of Research on Wildland Fire FRANK A. ALBINI Department of Mechanical and Industrial Engineering Montana State Univers~ty P.O. Box 173800 Bozeman MT 5971 7-3800 USA ABSTRACT This paper outlines the subject matter of research on the physics and phenomenology of' wildland fire, focusing on topics that bear upon issues of fire control and fire safety. Motivations for research on fire phenomenology are identified as arising from the activities necessary to achieve fire-related objectives, including acceptable levels of fire safety. Differences in the activities, techniques, and tactical objectives for control and prevention of' fires in natural fuels and in manmade structures are noted. Sources of wildland fire research information and operational planning aids are identified, and some cautions are ventured concerning their use by nonspecialists. KEYWORDS: Wildfire, wildland fire, natural fuels INTRODUCTION In preparing an overview of research on wildland fire, it is tempting simply to survey the literature of the field, outlining areas of investigation, pointing out significant findings and tracing the development of knowledge from early investigators to the present state of the art. But to bring such a survey to this audience of distinguished scientists with research interests in fire safety poses a unique challenge. This is because, while this group's efforts are focused mainly upon fire in manmade structures, many of its studies are relevant to, and are applied in, modeling of wildland fire phenomenology. But the converse does not seem to be the case. Results of wildland fire research are seldom cited in the literature of fire safety research as it is done by this audience. -
2018 Natural Hazard Report 2018 Natural Hazard Report G January 2019
2018 Natural Hazard Report 2018 Natural Hazard Report g January 2019 Executive Summary 2018 was an eventful year worldwide. Wildfires scorched the West Coast of the United States; Hurricanes Michael and Florence battered the Gulf and East Coast. Typhoons and cyclones alike devastated the Philippines, Hong Kong, Japan and Oman. Earthquakes caused mass casualties in Indonesia, business interruption in Japan and structure damage in Alaska. Volcanoes made the news in Hawaii, expanding the island’s terrain. 1,000-year flood events (or floods that are said statistically to have a 1 in 1,000 chance of occurring) took place in Maryland, North Carolina, South Carolina, Texas and Wisconsin once again. Severe convective storms pelted Dallas, Texas, and Colorado Springs, Colorado, with large hail while a rash of tornado outbreaks, spawning 82 tornadoes in total, occurred from Western Louisiana and Arkansas all the way down to Southern Florida and up to Western Virginia. According to the National Oceanic and Atmospheric Administration (NOAA)1, there were 11 weather and climate disaster events with losses exceeding $1 billion in the U.S. Although last year’s count of billion- dollar events is a decrease from the previous year, both 2017 and 2018 have tracked far above the 1980- 2017 annual average of $6 billion events. In this report, CoreLogic® takes stock of the 2018 events to protect homeowners and businesses from the financial devastation that often follows catastrophe. No one can stop a hurricane in its tracks or steady the ground from an earthquake, but with more information and an understanding of the risk, recovery can be accelerated and resiliency can be attained. -
Naian Liu 2020 Candidate Profile: the Combustion Institute Board of Directors
The Combustion Institute 5001 Baum Boulevard, Suite 644 Pittsburgh, Pennsylvania 15213-1851 USA Ph: (412) 687-1366 Fax: (412) 687-0340 [email protected] CombustionInstitute.org Naian Liu 2020 Candidate Profile: The Combustion Institute Board of Directors Reasons for Nomination Although fire has been a topic of interest to the Combustion Institute since its very foundation in 1958, our understanding of fire remains limited. As Hoyt C. Hottel (1903–1998) described, "A case can be made for fire being, next to life processes, the most complex of phenomena to understand". The complexity of fires comes from that there is a huge number of different fires that involve complex interactions among chemical reactions, heat transfer, and fluid mechanics, with diverse scenarios and controlling mechanisms. The discipline of fire science is less mature than other combustion topics, and more decades of fruitful research are required to gain a full understanding of this natural combustion phenomenon. My major motivation for serving the Board of Directors is to promote combustion research in the field of fire science. During the past 20 years, I have been dedicated to the theoretical and experimental studies on the combustion of extreme fire behaviors in large-scale fires. If elected to the Board of Directors, I will endeavor to promote cross-disciplinary research aiming at closer collaboration between combustion science and fire science. I commit to serve the international combustion community with the same rigor and enthusiasm that have enabled me to serve the fire community.

Fire Ecology of Ponderosa Pine and the Rebuilding of Fire-Resilient Ponderosa Pine Ecosystems 1
Fire Ecology of Ponderosa Pine and the Rebuilding of Fire-Resilient Ponderosa Pine Ecosystems 1 Stephen A. Fitzgerald2 Abstract The ponderosa pine ecosystems of the West have change dramatically since Euro-American settlement 140 years ago due to past land uses and the curtailment of natural fire. Today, ponderosa pine forests contain over abundance of fuel, and stand densities have increased from a range of 49-124 trees ha-1 (20-50 trees acre-1) to a range of 1235-2470 trees ha-1 (500 to 1000 stems acre-1). As a result, long-term tree, stand, and landscape health has been compromised and stand and landscape conditions now promote large, uncharacteristic wildfires. Reversing this trend is paramount. Improving the fire-resiliency of ponderosa pine forests requires understanding the connection between fire behavior and severity and forest structure and fuels. Restoration treatments (thinning, prescribed fire, mowing and other mechanical treatments) that reduce surface, ladder, and crown fuels can reduce fire severity and the potential for high-intensity crown fires. Understanding the historical role of fire in shaping ponderosa pine ecosystems is important for designing restoration treatments. Without intelligent, ecosystem-based restoration treatments in the near term, forest health and wildfire conditions will continue to deteriorate in the long term and the situation is not likely to rectify itself. Introduction Historically, ponderosa pine ecosystems have had an intimate and inseparable relationship with fire. No other disturbance has had such a re-occurring influence on the development and maintenance of ponderosa pine ecosystems. Historically this relationship with fire varied somewhat across the range of ponderosa pine, and it varied temporally in concert with changes in climate. -
