Deformation of PMMA samples in cone calorimeter and anaerobic gasification experiments

October 20, 2024
Author(s)
Karen De Lannoye, Isaac Leventon, Lucie Hasalova, Alexander Belt, Ernst-Arndt Reinecke, Lukas Arnold
16 Cone calorimetry and anaerobic gasification experiments are often used to assess material 17 flammability of bench-scale (coupon sized) samples in response to well-characterized external radiant 18 heating. In this project, it has been observed that the

Detailed radiation modeling of two flames relevant to fire simulation using Photon Monte Carlo - Line by Line radiation model

September 5, 2024
Author(s)
Chandan Paul, Somesh Roy, Johannes Sailer, Fabian Braennstroem, Mohamed Ahmed, Arnaud Trouve, Hadi Bordbar, Simo Hostikka, Randall J. McDermott
This work reports benchmark data sets for radiative heat transfer in two distinct fire configurations obtained from the Measurement and Computation of Fire Phenomena (MaCFP) working group database. The cases include a 19.2 kW non-sooting turbulent methanol

Detecting Firefighter's Tenability Utilizing Machine Learning

August 30, 2024
Author(s)
Qi Tong, Hongqiang FANG, Eugene Yujun Fu, Wai Cheong Tam, Thomas Gernay
The proposed research aims to leverage machine learning to detect thermal operating classes and improve the tenability of firefighters in a commercial building. A total of 3000 simulations are run with FDS to collect temperature from heat detectors. The

Report on High Energy Arcing Fault Experiments - International Experimental Results from Bus Duct and Switchgear Enclosures

July 1, 2024
Author(s)
Gabriel Taylor, Anthony D. Putorti Jr., Scott Bareham, Christopher U. Brown, Wai Cheong Tam, Michael Heck, Lucy Fox, Stephen Fink, Michael Selepak, Edward Hnetkovsky, Nicholas Melly, Kenneth Hamburger, Kenneth Miller
This report documents an experimental program designed to collect data and information to evaluate the performance of models developed to estimate the electrical high energy arcing fault (HEAF) hazard. This report covers full-scale laboratory experiments

Comparison of Flow Measurement Devices for Large Fire Experiments

April 12, 2024
Author(s)
Giovanni Di Cristina Torres, Rodney Bryant
Bi-directional probes are utilized throughout fire research and testing to measure fire induced flows due to their ability to measure flow which changes direction, and to withstand hostile environments. However, they are not available commercially and

Estimations of Photopheresis and Thermophoresis Impacts on Soot Particle Velocity

March 12, 2024
Author(s)
Emma Veley, Amy Mensch, Ryan Falkenstein-Smith, Thomas Cleary
The dissemination of soot particles onto surfaces in a compartment fire is affected by local radiation and temperature gradients. Subsequently, any deposition model must account for the influence of photopheresis and thermophoresis on the deposition

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

Building Fire Hazard Predictions Using Machine Learning

January 26, 2024
Author(s)
Eugene Yujun Fu, Wai Cheong Tam, Tianhang Zhang, Xinyan Huang
The lack of information on the fire ground has always been the leading factor in making wrong decisions . Wrong decisions can be made by individual firefighters, their local chiefs, and/or the incident commander. Any wrong decision at any level (scale)

New Fire Protection Materials

January 26, 2024
Author(s)
Andre Thompson
Residential upholstered furniture (RUF) is the leading combustible in fatal fires in the United States. In the last few decades, fire-retardant (FRs) chemicals have been largely used in attempt to reduce RUF flammability; however, concerns about possible

The persistence of smoke VOCs indoors: partitioning, surface cleaning, and air cleaning in a smoke-contaminated house

October 13, 2023
Author(s)
Jienan Li, Michael F. Link, Shubhrangshu Pandit, Marc Webb, Cholaphan Deeleepojananan, Kathryn Mayer, Lauren Garofalo, Katelyn Rediger, Dustin Poppendieck, Stephen Zimmerman, Marina Vance, Vicki Grassian, Glenn Morrison, Barbara Turpin, Delphine Farmer
Wildfires are increasing in frequency, raising concerns that smoke can permeate indoor environments and expose people to chemical air contaminants. To study smoke transformations in indoor environments and evaluate mitigation strategies, we added smoke to

Report on High Energy Arcing Fault Experiments: Experimental Results from Medium-Voltage Bus Duct and Switchgear Enclosures

September 15, 2023
Author(s)
Gabriel Taylor, Anthony D. Putorti Jr., Scott Bareham, Christopher U. Brown, Wai Cheong Tam, Ryan Falkenstein-Smith, Stephen Fink, Michael Heck, Edward Hnetkovsky, Nicholas Melly, Kenneth Hamburger, Kenneth Miller
This report documents an experimental program designed to investigate high energy arcing fault (HEAF) phenomena for medium-voltage, metal-enclosed bus ducts and switchgear. This report covers full-scale laboratory experiments using representative nuclear

National Institute of Standards and Technology Environmental Scan 2023: Societal and Technology Landscape to Inform Science and Technology Research

August 23, 2023
Author(s)
Ashley Boggs-Russell, Kerrianne Buchanan, David W. Griffith, Heather Evans, Dimitrios Meritis, Lisa Ng, Anna Sberegaeva, Michelle Stephens
The 2023 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 three separate lenses

An analysis of the sensitivity of the rate of buoyancy-driven flame spread on a solid material to uncertainties in the pyrolysis and combustion properties. Is accurate prediction possible?

August 1, 2023
Author(s)
Yan Ding, Isaac Leventon, Stanislav Stoliarov
An upward, buoyancy-driven flame spread on combustible solids is frequently the dominant contributor to the growth of fire in built environment. Thus, an ability to accurately predict the development of a fire is strongly linked to the accuracy of flame
