Prediction of the Burning Rate of Non-Charring Polymers

January 1, 2009
Author(s)
Stanislav Stoliarov, Sean Crowley, R Lyon, Gregory T. Linteris
This study demonstrates that a numerical pyrolysis model called ThermaKin, which was developed by SRA International, Inc. and the Federal Aviation Administration, can be used to predict and extrapolate the results of gasification and cone calorimetry

Flame Size, Heat Release, and Smoke Points in Materials Flammability

August 1, 2008
Author(s)
Gregory T. Linteris, I P. Rafferty
The concept of using the flame size as a surrogate for heat release rate has been explored. A technique for simultaneously obtaining the heat release rate, flame size (height and area), and the smoke point of the flame solely from visual images has been

Catalytic Inhibition of Laminar Flames by Transition Metal Compounds

June 1, 2008
Author(s)
Gregory T. Linteris, M D. Rumminger, Valeri I. Babushok
Some of the most effective flame inhibitors ever found are metallic compounds. Their effectiveness, however, drops off rapidly with an increase of agent concentration, and varies widely with flame type. Iron pentacarbonyl, for example, can be up to two

Further Studies of Cup-Burner Flame Extinguishment.

May 16, 2006
Author(s)
F Takahashi, Gregory T. Linteris, Vishwanath R. Katta
The structure and extinguishment of heptane-air co-flow diffusion flames formed on a cup burner in normal earth gravity have been studied experimentally and computationally. A gaseous fire-extinguishing agent (CO2) was introduced gradually into a coflowing

NGP RESEARCH ON FIRE SUPPRESSION CHEMISTRY

January 1, 2006
Author(s)
Gregory T. Linteris
Several NGP projects studied the mechanisms of chemical suppressants, including those containing halogens, phosphorus, and metals. From the work, several general principles of chemical flame inhibition are outlined. The present paper describes the

Modeling Solid Sample Burning With FDS

June 1, 2005
Author(s)
Gregory T. Linteris, L W. Gewuerz, Kevin B. McGrattan, Glenn P. Forney
Black PMMA was burned in the cone calorimeter in two orientations (horizontal and vertical), at imposed radiant heat fluxes of (0, 5, 10, 25, 50, and 75) kW/m2, and the visual appearance, flame size, heat release rate, and mass loss rate were recorded

Flame Extinguishment in a Cup-Burner Apparatus

March 1, 2005
Author(s)
F Takahashi, Gregory T. Linteris, V Katta
Unsteady extinguishment phenomena of laminar methane-air co-flow diffusion flames formed in a cup-burner apparatus at normal earth gravity have been studied experimentally and computationally. A gaseous fire-extinguishing agent (CO 2, N 2, He, Ar, or CF 3H

Extinguishment of Cup-Burner Flames in Low Gravity

January 1, 2005
Author(s)
F Takahashi, Gregory T. Linteris, V Katta
The effects of oxidizer stream velocity and oxygen concentration, as well as gravity and pressure, on the extinguishment limits of laminar co-flow diffusion flames of methane, formed in a cup-burner apparatus, have been studied experimentally and

Limits to the Effectiveness of Metal-Containing Fire Suppressants

December 1, 2004
Author(s)
Gregory T. Linteris
This report reviews the literature on metal inhibition of flames and identifies metal species with potential as fire suppressant additives. To provide a basis for discussion, the detailed mechanism of inhibition of iron is reviewed, and the reasons for its

Suppression of Cup-Burner Flames Using Carbon Dioxide in Microgravity

April 1, 2004
Author(s)
V Katta, F Takahashi, Gregory T. Linteris
Carbon dioxide extinguishes flames through dilution process. The extinction characteristics of CO2 were previously studied using a cup-burner flame under normal-gravity conditions. As the diffusion flames behave differently in microgravity compared to
