The Character of Residential Cooktop Fires

January 8, 2021
Author(s)
Yue Hu, Jian Chen, Zhigang Wang, Ki Yong Lee, Matthew 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
Author(s)
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

Numerical and Experimental Studies of Extinguishment of Cup-Burner Flames by C6F12O

August 1, 2020
Author(s)
Fumiaki Takahashi, Viswanath R. Katta, Valeri I. Babushok, Gregory T. Linteris
The extinguishment processes of cup-burner flames by adding a halon-replacement fire-extinguishing agent C6F12O (Novec 1230) to coflowing air in normal gravity have been studied computationally and experimentally. The time-dependent, axisymmetric numerical

The Characteristics of a 1 m Methanol Pool Fire

May 4, 2020
Author(s)
Kunhyuk Sung, Jian Chen, Matthew Bundy, Anthony 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
Author(s)
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
Author(s)
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
Author(s)
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

Influence of Board Spacing on Mitigating Wood Decking Assembly Ignition

November 17, 2019
Author(s)
Samuel L. Manzello, Sayaka Suzuki
As part of recent building code change discussions, it has been suggested that by increasing the spacing of boards, it may be possible to mitigate ignition of wood decking assemblies from wind-driven firebrand showers. An experimental series was undertaken

Design of the ASTM E119 fire environment in a large compartment

November 1, 2019
Author(s)
Chao Zhang, William L. Grosshandler, Ana Sauca, Lisa Y. Choe
This paper presents a basis for designing the ASTM E119 fire environment in a large compartment of about 10 m wide, 7 m deep and 3.8 m high constructed in the National Fire Research Laboratory of the National Institute of Standards and Technology. Using

Development of a Standard Fire Condition for a Large Compartment Floor Assembly

October 22, 2019
Author(s)
Ana Sauca, Chao Zhang, William L. Grosshandler, Matthew Bundy, Lisa Choe
This report presents the experimental investigation of a test fire in a large compartment of about 10 m wide, 7 m deep and 3.8 m high constructed in the National Fire Research Laboratory of the National Institute of Standards and Technology. The test fire

Role of Firebrand Combustion in Large Outdoor Fire Spread

October 4, 2019
Author(s)
Samuel L. Manzello, Sayaka Suzuki, Michael Gollner, A C. Fernandez-Pello
Large outdoor fires are an increasing danger to the built environment. Wildfires that spread into com- munities, labeled as Wildland-Urban Interface (WUI) fires, are an example of large outdoor fires. Other examples of large outdoor fires are urban fires
