PREFACE This report describes the research projects performed in the Center for Fire Research (CFR) and under its grants program during FY-1988. The Center is nationally recognized as the focal point for fire research and is the largest and most comprehensive fire research laboratory in the world, with an extremely competent multi-disciplinary technical staff that is supported by an excellent fire library and extensive laboratory facilities. The Center was created by the Federal Fire Prevention and Control Act of 1974 which authorized the Secretary of Commerce, through the Center, to conduct a fire research program directly or through contracts or grants. Therefore, in addition to its in-house program, the Center maintains a fire research grants program that supplements most of the in-house programs and supports most of the academic fire research in the country. The Center, as a component of the National Institute of Standards and Technology (formerly the National Bureau of Standards) responds to the needs of other Federal agencies and private , sector organizations. This report covers work performed with funds appropriated to the Center and work performed under contract to other agencies The goal of the Center's program is to provide the technical basis for the reduction of losses and costs of fire. The program is designed to upgrade the knowledge of fire and the production of usable products to meet the fire safety needs of the public, the fire services, and the manufacturing industry. It is comprised of three elements: • Basic research leading to the development of tools for "engineered" fire safety; i.e., fire protection technologies and fire prediction methods as demonstrated in such CFR fire models as: FIREFOAM, HAZARD, and CCFM. • Timely response to current fire problems; for example, smoke toxicity, hazards of upholstered furniture, investigations support and fire reconstructions. • Serves as a focal point for fire research in the nation by incorporating in its program academic and foreign Guest Researchers, collaborating and cooperating with international work in fire research, conducting fire simulation lab workshops; as well as technology transfer and support activities such as standards and codes participation, FRIS, the Computer Bulletin Board, NFRSC, meetings, etc. (Note: For FY-89, the Center's program has been expanded in the areas of smoke toxicity and upholstered furniture flammability. Progress on these projects will be reported in next year's report.) The majority of our in-house priority projects and grants work fits into the first category, basic research and tools for engineered fire safety, and is 1 . : presented in Part I of this report. Our work for other agencies fits in the second, timely response to current fire problems, and is presented in Part II. Activities under the third element are diverse and are not included in this report Part I is organized to reflect the way in which the grants augment and support the in-house program. Therefore, each grant report is presented immediately following its related in-house priority project. The projects are arranged in five groups: Fire/Materials Interaction Fire Dynamic Processes Compartment Fire Modeling Hazard Modeling Fire Protection Technology Technology Transfer The projects for other agencies, presented in Part II, although usually related to internally funded projects, are primarily designed to meet the

  • 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.

    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.

    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 Evatt Hawkes 2020 Candidate Profile: The Combustion Institute Board of Directors Reasons for Nomination I feel privileged to have a career in combustion research. It is such a wonderful topic that is both incredibly important to society and incredibly rich from an academic perspective. I strongly believe that combustion will retain this importance and interest. Nonetheless, the Combustion Institute (CI) faces some challenges going forwards. Foremost is the growing perception that combustion-based energy is in decline, as renewables now offer a credible alternative in some applications. The second is a long- standing need to improve the connections to industry. Finally, while the CI has progressed in encouraging diversity and supporting the career development of early- and mid-career combustion researchers, more can be done. As a member of the Board I would initiate and support efforts to address these challenges, by a combination of improved outreach, engagement, and mechanisms to provide recognition. For instance, in my role on the Board of the Australia and New Zealand section, I led submissions from the section advising the Australian government, enhanced membership by reaching out to fire and hypersonic combustion communities, served on the section’s committee to identify and nominate CI Fellows, initiated in collaboration with the chair the establishment of an early- career prize for members of our section.

PATEL Fire Safety Engineering Group University of Greenwich London SE 18 6PF, UK ABSTRACT In this paper we present some early work concerned with the development of a simple solid fuel combustion model incorporated within a Computational Fluid Dynamics (CFD) framework The model is intended for use in engineering applications of fire field modelling and represents an extension of this technique to situations involving the combustion of solid cellulosic hels A simple solid &el combustion model consisting of a thermal pyrolysis model, a six flux radiation model and an eddy- dissipation model for gaseous combustion have been developed and implemented within the CFD code CFDS-FLOW3D The model is briefly described and demonstrated through two applications involving fire spread in a compartment with a plywood lined ceiling. The two scenarios considered involve a fire in an open and closed compartment The model is shown to be able to qualitatively predict behaviours similar to flashover - in the case of the open room - and backdrafl - in the case of the initially closed room. KEYWORDS: CFD, field model, pyrolysis, solid fuel combustion, flashover, backdraft INTRODUCTION Over the past 10 years considerable effort has been expended in developing fire field models capable of predicting the development of hazardous conditions within fire enclosures[l-41. At the heart of these fire field models is the Computational Fluid Dynamics (CFD) code and a large proportion of these models are based on commercial CFD software such as PHOENICS[S] and FLOW3D[6].

  • The Science of Wood Combustion
    Proc. Indian Acad. ScL (Engg. Sci.), Vol. 5, Pt. 4, December 1982, pp. 259-268. ~) Printed in India The science of wood combustion HOWARD W EMMONS and ARVIND ATREYA Division of Applied Sciences, Harvard University, Cambridge, Massachusetts 02138. USA Abstract. The purpose of this paper is to provide an introduction to the physical processes involved in the combustion of wood and other cellulosic fuels. This introduction is aimed towards the utilization of the cellulosic fuels as an energy source. A discussion of a design of the stove is also provided to aid the develop- ment of such a device. Keywords. Pyrolysis;flames; charburning; heat; stove. 1. Introduction Fire from natural causes has been known to man and animals from the beginnings of life on earth. A momentous event occurred when man discovered that fire could be controlled and used in many ways. The easy availability of wood and other cellulosic materials has provided an abundance of natural, renewable energy resource. Even before fire was tamed, man no doubt knew that wood subject to fire first produced white smoke, then flamed, then glowed as a pile of embers and then cooled offas a small pile of grey ashes. Today with our extensive knowledge of the physical laws which govern the universe, our scientific knowledge of many of the details of the wood burning process has begun to be clarified but is far from complete. In this paper, we will briefly review some of what is now known about the burning properties of wood and the resultant fire. The next major step in understanding combustion of any material is summarized in the fire triangle (figure 1).
