Characterization of backdrafts generated from methane fires

March 10, 2022
Author(s)
Ryan Falkenstein-Smith, Christopher U. Brown, Thomas Cleary
An analysis of oxygen concentration measurements is conducted to investigate compartment ventilation before a potential backdraft phenomenon. Experiments are performed in a 2/5th scale compartment of varying configurations such as fuel flow time, spark

WUI Structure/Parcel/Community Fire Hazard Mitigation Methodology

March 1, 2022
Author(s)
Alexander Maranghides, Eric Link, Shonali Nazare, Steven Hawks, Jim McDougald, Stephen Quarles, Daniel Gorham
In the last twenty years, wildland-urban interface (WUI) fires have been growing in severity and size. The structures destroyed by WUI fires have devastated entire communities and have cost billions of dollars while significantly impacting the social

The Design and Performance of a Second-Generation Phi Meter

January 5, 2022
Author(s)
Ryan Falkenstein-Smith, Thomas Cleary
This report documents the design and performance of a second-generation phi meter used in multi-scale experimental applications. A constructed second-generation phi meter is implemented in bench and 2/5th scale experiments to demonstrate the instrument's

A Generic Flashover Prediction Model for Residential Buildings Using Graph Neural Network

November 11, 2021
Author(s)
Wai Cheong Tam, Eugene Yujun Fu, Paul A. Reneke, Richard D. Peacock, Thomas Cleary
A generic graph neural network-based model is developed to predict the potential occurrence of flashover for different building structures. The proposed model transforms multivariate temperature data into graph-structure data. Utilizing graph convolution

Characteristics of Nuclear Power Plant Fires Involving Electrical Enclosures

November 10, 2021
Author(s)
Isaac Leventon, Kenneth Hamburger, Kevin B. McGrattan, Rick D. Davis
PRIMARY AUDIENCE Fire protection and fire probabilistic risk assessment engineers conducting or reviewing fire modeling that supports fire probabilistic risk assessments related to characteristics (e.g., ignition, fire growth, and peak heat release rate)

Human Behavior in Home Fires

November 9, 2021
Author(s)
Stanley W. Gilbert
Casualties in fires--and in particular, deaths--are tail events. The average fire does not cause deaths or injuries. There is increasing evidence that the people susceptible to dying in fires are a specific subset of the people in homes. It seems likely

Response Time Impact of Smoke Alarms

September 9, 2021
Author(s)
Stanley W. Gilbert, Thomas Cleary, Paul A. Reneke, Richard Peacock, David Butry
It can be assumed that smoke alarms reduce reported fires and casualties by reducing on average the amount of time it takes to detect a fire. This paper sets out to determine by how much that detection time is reduced. It does so by comparing the effect of
