February 5, 2025
Author(s)
Erik Johnsson, Giovanni Di Cristina Torres, Eric Mueller, Matthew Bundy, Anthony Chakalis, Marco Fernandez, Anthony Hamins
A series of experiments are reported on the burning behavior of dry, 3 m to 6 m tall, Douglas fir trees. The measurements were conducted in the open under quasi-quiescent conditions. The global measurements reported include the transient, peak, and total

The Global and Local Structure of Medium-Scale Pool Fires

October 24, 2024
Author(s)
Kunhyuk Sung, Ryan Falkenstein-Smith, Matthew Bundy, Marco Fernandez, Anthony Hamins
A series of experiments are reported that characterize key features of the structure of eight medium-scale pool fires (0.3 m to 0. 4 m) burning a variety of liquid and gaseous fuel types, including 30 cm diameter liquid pool fires burning methanol, ethanol

Compartment fires: challenges for fire modeling as a tool for safe design

February 1, 2024
Author(s)
Tarek Beji, Talal Fateh, Jason Floyd, hugues Pretrel, Anthony Hamins
The use of fire models to support fire protection engineering decisions requires an understanding of model shortcomings and assurance in their predictive robustness. This note is a summary of the online 'compartment fire' workshop that was organized prior

Heats of Combustion and Related Properties of Pure Substances

December 5, 2023
Author(s)
Donald R. Burgess Jr., Anthony Hamins
In this work, we compiled and evaluated various properties pertaining to the heats of combustion of about 420 compounds of physical, chemical, and engineering interest. This includes boiling points, melting points, latent heats (enthalpies) of vaporization

Measuring Firebrand Heat Flux with a Thin-Skin Calorimeter

July 11, 2023
Author(s)
Amy Mensch, Savannah Wessies, Anthony Hamins, Jiann C. Yang
While the impact of wildland-urban interface fires is growing, firebrand exposure is a significant but not well understood contributor to fire spread. The ignition threat of firebrand exposures can be characterized by measuring the heat transfer of glowing

Experimental Studies on the Heat Flux of Individual Firebrands

March 22, 2023
Author(s)
Amy Mensch, Savannah Wessies, Anthony Hamins, Jiann C. Yang
Every year, thousands of wildfires burn all over the world threatening lives and property in the wildland-urban interface. These wildland-urban interface fires spread by radiation, direct flame contact, or firebrand transport. Firebrand exposures are a

The Structure of Medium-Scale Pool Fires

January 5, 2022
Author(s)
Ryan Falkenstein-Smith, Kunhyuk Sung, Jian Chen, Kimberly Harris, Anthony Hamins
This report documents a series of time-averaged gas species measurements made along the centerline of methanol, ethanol, acetone, methane, and propane pool fires steadily burning in a quiescent environment. All gas species measurements are obtained using a

The structure of medium-scale propane pool fires

September 23, 2021
Author(s)
Ryan Falkenstein-Smith, Kunhyuk Sung, Anthony Hamins
A series of time-averaged temperature, velocity, and gas species measurements are made along the centerline of propane fires established on a 37 cm diameter gas burner situated in a quiescent environment. Fires with heat release rates of 20 kW and 34 kW

Demonstration of an all-in-one solution for fire safe upholstery furniture: A benign backcoating for smoldering and flame-resistant cover fabrics

August 15, 2021
Author(s)
Ickchan Kim, Andre Thompson, Sung Chan Kim, Anthony Hamins, Matthew Bundy, Shonali Nazare, Rick D. Davis, Mauro Zammarano
The development of fire prevention and mitigation technologies with a benign toxicological and environmental profile has become of particular interest in the USA due to the recent adoption of state regulations that severely restrict the use of flame

Sensors and Machine Learning Models to Prevent Cooktop Ignition and Ignore Normal Cooking

July 28, 2021
Author(s)
Amy Mensch, Anthony Hamins, Wai Cheong Tam, John Lu, Kathryn Markell, Christina You, Matthew Kupferschmid
According to a recent NFPA report, 49 % of reported home fires involve cooking equipment, with cooktops accounting for 87 % of cooking-fire deaths and 80 % of the civilian injuries [1, 2]. Between 2014–2018, U.S. fire departments responded to an estimated
