Velocity and Temperature Structure of Medium-Scale Pool Fires

June 22, 2021
Kunhyuk Sung, Ryan Falkenstein-Smith, Anthony Hamins
A series of measurements was conducted using a bidirectional probe to characterize the upward speed in the plumes of medium-scale pool fires burning a variety of gaseous and liquid fuels. Time-averaged local measurements of the upward velocity were

Investigating Firebrand Deposition Processes in Large Outdoor Fires

May 27, 2021
sayaka suzuki, Samuel Manzello
Devastating large outdoor fires have been responsible for destruction of vast amounts of infrastructure and loss of human life. Wildland fires that spread into urban areas, known as wildland-urban interface (WUI) fires, are capable of enormous destruction

The Combustion of Noble-Fir Trees in the Presence of an Applied Wind Field

May 27, 2021
Samuel Manzello, sayaka suzuki
Wildland fires that spread into urban areas, termed wildland-urban interface (WUI) fires, are becoming more and more common across multiple locations of the world. An important component in rapid spread of large outdoor fires is the production or

Structure Separation Experiments Phase 1 Preliminary Test Plan

May 26, 2021
Alexander Maranghides, Shonali Nazare, Eric Link, Kuldeep Prasad, Matthew Hoehler, Matthew Bundy, Steven Hawks, Frank Bigelow, William (Ruddy) Mell, Anthony Bova, Derek McNamara, Tom Milac, Daniel Gorham, Faraz Hedayati, Bob Raymer, Frank Frievalt, William Walton
The primary objective of this project is to assess structure-to-structure fire spread for structures located in the Wildland Urban Interface (WUI). Full-scale fire experiments will be conducted in which various types of structures (sources of fire) will be

National Institute of Standards and Technology Environmental Scan 2020

February 9, 2021
Heather M. Evans, Kristen Greene, William M. Healy, Elizabeth A. Hoffman, Catherine A. Rimmer, Anna V. Sberegaeva, Neil M. Zimmerman
The 2020 National Institute of Standards and Technology Environmental Scan provides an analysis of key external factors that could impact NIST and the fulfillment of its mission in coming years. The analyses were conducted through four separate lenses

A Case Study of the Camp Fire - Fire Progression Timeline

February 8, 2021
Alexander Maranghides, Eric D. Link, Christopher U. Brown, William Mell, Steven Hawks, Mike Wilson, Will Brewer, Robert Vihnanek, William D. Walton
The Camp Fire ignited on November 8, 2018 in the foothills of the Sierra Nevada in Butte County, California. The first 24 hours were characterized by a fast-moving fire with initial spread driven by high winds up to 22 m/s (50 mi/h) and long-range spotting

The Character of Residential Cooktop Fires

January 8, 2021
Yue Hu, Jian Chen, Zhigang Wang, Ki Yong Lee, Matthew F. Bundy, Anthony Hamins, Marco G. Fernandez
A series of experiments was conducted to investigate the pre-combustion and combustion properties of corn oil heated in pans from 10 cm to 26 cm diameter by a residential electric- coil element cooktop. For comparison, torch-ignited gasoline, heptane and

Large Outdoor Fires and the Built Environment (LOF&BE): Summary of Virtual Workshop

November 4, 2020
Samuel L. Manzello, Sayaka Suzuki, Sara McAllister, Brian Lattimer, Daniel Gorham, Alexander Filkov, Maria Theodori, Xinyan Huang
Two virtual workshops 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), were held this past August (2020). The first session was held

The Characteristics of a 1 m Methanol Pool Fire

May 4, 2020
Kunhyuk Sung, Jian Chen, Matthew F. Bundy, Anthony P. Hamins
A series of measurements was made to characterize the structure of a 1 m diameter methyl 12 alcohol (methanol; CH3OH) pool fire steadily burning with a constant lip height in a quiescent 13 environment. Time-averaged local measurements of gas-phase

Analysis of a Slug Calorimeter with a Curie Point

April 3, 2020
Jiann C. Yang, Thomas J. Ohlemiller
A lump-capacitance heat transfer model was developed to model the operation of a slug calorimeter constructed of metal with a Curie point. The resulting formula has been successfully used to infer total heat flux to a metal structural member in a fire by

Intumescent Polydopamine Coatings for Fire Protection

March 9, 2020
Douglas M. Fox, Whirang Cho, Laura J. Dubrulle, Phillip Grutzmacher, Mauro Zammarano, Douglas M. Fox
Polydopamine coatings containing additional bioderived flame retardants were used as coatings for polyurethane foam and cardboard. The ability to form intumescing coatings was crucial for achieving good flame protection. Dopamine can effectively

SUPPLEMENTARY COMPARISON CCT Supplementary comparison S2 on thermal conductivity measurements of insulating materials by guarded hot plate

January 1, 2020
Bruno Hay, Robert R. Zarr, Clark Stacey, Nikolay Sokolov, Leonel Lira Cortes, Ulf Hammerschmidt, Jintao Zhang, Jean Remy Filtz, Fleurence N.
Seven National Metrology Institutes (NMIs) from France, United States, United Kingdom, Russia, Mexico, China and Germany participated in an inter-laboratory comparison on thermal conductivity measurements by the Guarded Hot Plate method. This action was
