On Correlating Mixed Forest Fuel Bed Fire Spread Data

September 13, 2019
Author(s)
Jiann C. Yang
Mixing rules are proposed and used to correlate well-mixed forest fuel bed fire spread data from the literature using the dimensionless correlations previously developed for single-species forest fuel bed fire spread with the help of dimensional analysis

August 29, 2019
Author(s)
Samuel L. Manzello, Sara McAllister, Sayaka Suzuki, Raphaele Blanchi, Elsa Pastor, Ronchi Enrico
A workshop of the permanent working group, sponsored by the International Association for Fire Safety Science (IAFSS), entitled Large Outdoor Fires and the Built Environment(LOF&BE) was held from 2:00 pm to 4:00 pm on Sunday June 30, 2019. The workshop was

A Modelling Framework for Householder Decision-Making for Wildfire Emergencies

August 14, 2019
Author(s)
Ruggiero Lovreglio, Erica D. Kuligowski, Steve Gwynne, Ken Strahan
The occurrence of wildfire threats has dramatically increased in the last few decades creating serious challenges for hundreds of thousands of communities around the world. Understanding the physical and social dynamics characterizing wildfires is

Pre-Fire and Post-Fire Data Studies in the WUI

June 19, 2019
Author(s)
Eric D. Link
Pre-Fire and Post-Fire Data Studies in the WUI are a systematic effort to document and understand the fire and ember exposure, and consequential damage, from a wildland fire which burned into a developed area. The purpose of such studies is to provide a

On the Importance of Firebrand Processes in Large Outdoor Fires

May 15, 2019
Author(s)
Samuel L. Manzello
Firebrands are produced from combustion of both vegetative and structural fuels in large outdoor fires. It is well known that firebrand generation, transport, and ignition mechanisms result in rapid and potentially devastating fire spread processes in

Modelling and Mapping Dynamic Vulnerability to Better Assess WUI Evacuation Performance

May 2, 2019
Author(s)
Steve Gwynne, Ronchi Enrico, Noureddine Benichou, Max Kinateder, Erica D. Kuligowski, Islam Gomaa, Masoud Adelzadeh
Wildland-Urban Interface (WUI) incidents are likely to become more severe and will affect more and more people. Given their scale and complexity, WUI incidents require a multi-domain approach to assess their impact and the effectiveness of any mitigation

Measurement of the Flow Resistance of Vegetation

April 1, 2019
Author(s)
Ryan L. Falkenstein-Smith, Kevin B. McGrattan, Blaza Toman, Marco G. Fernandez
This report documents the measurement of the wind resistance of different types of vegetation. The measurements are made in a wind tunnel with a 2.0 m test section and 0.5 m by 0.5 m cross- section. Samples of vegetation have been cut into cubical volumes

Large Outdoor Fires and the Built Environment: Summary of Kick-Off Workshop

February 4, 2019
Author(s)
Samuel L. Manzello, Sara McAllister, Sayaka Suzuki, Raphaele Blanchi, Elsa Pastor, Ronchi Enrico
The kickoff workshop of the new permanent working group, sponsored by the International Association for Fire Safety Science (IAFSS), entitled Large Outdoor Fires and the Built Environment was held from 3:00 pm to 4:30 pm on Sunday October 21, 2018. The

Summary of Workshop on Global Overview of Large Outdoor Fire Standards

February 4, 2019
Author(s)
Samuel L. Manzello
Large outdoor fires have the potential to negatively impact the built environment. Wildland fires that spread into communities, known as wildland-urban interface (WUI) fires have become a global problem. Large urban fires, including those that have

On the use of time-resolved 3D diagnostics to characterize firebrand showers in the WUI

January 1, 2019
Author(s)
Nicolas Bouvet, Eric D. Link, Stephen A. Fink, Erica D. Kuligowski
NIST is currently developing a time-resolved, three-dimensional particle tracking and sizing diagnostic (a.k.a an “emberometer”) that will be applied to airborne firebrands during wildland- urban interface fires. The present paper provides an overview of

Ignition of Japanese style tile roofing assemblies exposed to firebrands

November 14, 2018
Author(s)
Samuel L. Manzello, Sayaka Suzuki
In a recent urban fire in Itoigawa-city, Niigata, Japan, structures were exposed to firebrands and it was reported roofing assemblies were ignited, which led to loss of entire structures. Roof tiles are fabricated using non-combustible materials yet the
