Exploratory Study of Airflow from SCBA Exposed to Elevated Temperatures

September 18, 2013
Author(s)
Michelle K. Donnelly, Daniel M. Madrzykowski, Anthony D. Putorti Jr.
This exploratory set of experiments investigated the impact of external exposure temperatures on Self Contained Breathing Apparatus (SCBA) supply air, and the potential for the supply air to be heated when it is subjected to an elevated temperature

Lateral torsional buckling of steel W-beams subjected to localized fires

September 1, 2013
Author(s)
Chao Zhang, John L. Gross, Therese P. McAllister
Current design approaches to assess the lateral torsional buckling capacity of steel beams in fire are based on the assumption of uniform steel temperature. This paper investigates the effect of temperature gradients on the lateral torsional buckling

POST-COLLISION VEHICLE FIRE SUPPRESSION RESEARCH NEEDS

September 1, 2013
Author(s)
Anthony P. Hamins
This article identifies research needs in automotive fire protection. The work focuses on the problem of post-collision vehicle fires. Recent fire suppression research is cited with special attention given to results cited in the literature as well as

Uncertainties in Steel Temperatures during Fire

August 4, 2013
Author(s)
Dilip K. Banerjee
In order to determine the fire resistance of steel members, steel temperatures must be estimated with a high confidence. There can be considerable uncertainty in temperatures of both protected and unprotected steels during fire exposure. This is due to

The Effects of Wildfire Prevention Activities

August 1, 2013
Author(s)
Douglas S. Thomas, David T. Butry, Jeffrey P. Prestemon
Eighty percent of wildfires are human caused, so it is important for decision makers and land managers to consider the role of prevention activities that minimize the costs and losses of human-caused wildfires. There have been significant efforts aimed at

Measurements of effective diffusion coefficients of helium and hydrogen through gypsum

July 3, 2013
Author(s)
Jiann C. Yang, William M. Pitts, Marco G. Fernandez, Kuldeep R. Prasad
An experimental apparatus, which was based on the ¿-scale garage previously used for studying helium release and dispersion in our laboratory, was used to obtain effective diffusion coefficients of helium and hydrogen (released as forming gas for safety

Experimental study of radiative heat transfer in a translucent fuel sample exposed to different spectral sources

June 28, 2013
Author(s)
Gregory T. Linteris, Nicolas Ball, J. Raynard, Guillermo Rein, Jose L. Torero, M. Forsth, P. Boulet, G. Parent, Z. Acem
Radiative heat transfer to a solid is a key mechanism in fire dynamics, and in-depth absorption is especially of importance for translucent fuels. The sample-heater interaction for radiative heat transfer is experimentally investigated in this study with
