Structure and Soot Properties of Nonbuoyant Ethylene/Air Laminar Jet Diffusion Flames

August 1, 1998
Author(s)
D L. Urban, Zeng-guang Yuan, Peter B. Sunderland, Gregory T. Linteris, J. E. Voss, Kenneth Lin, Z Dai, Kairan Sun
The structure and soot properties of round, soot-emitting, nonbuoyant, laminar jet diffusion flames are described, based on long-duration (175-230-s) experiments at microgravity carried out on orbit in the Space Shuttle Columbia. Experimental conditions

Chemical Effects of CF3H in Extinguishing Counterflow CO/Air/H2 Diffusion Flames

July 28, 1996
Author(s)
G. S. Fallon, H K. Chelliah, Gregory T. Linteris
The relative importance of introducing CF3H as a fire suppressant with the oxidizer or the fuel stream, and its chemical and thermal effects on the extinction condition of counterflow CO/air/H2 diffusion flames, are investigated both experimentally and

Chemical Effects of CF3H in Extinguishing Counterflow CO/Air/H2 Diffusion Flames.

Gregory T. Linteris, G S. Fallon, H K. Chelliah
The relative importance of introducing CF3H as a fire suppressant with the oxidizer or the fuel stream, and its chemical and thermal effects on the extinction condition of counterflow CO/air/H2 diffusion flames, are investigated both experimentally and

Inhibition of Premixed Methane-Air Flames by Fluoromethanes

April 1, 1996
Author(s)
Gregory T. Linteris, L Truett
This paper presents the first calculations and measurements of the burning velocity of premixed hydrocarbon flames inhibited by the three one-carbon fluorinated species CH2F2, CF3H, and CF4. The chemistry of these agents is expected to be similar to that

Inhibition of Flames by Condensed-Phase Agents

March 26, 1996
Author(s)
Gregory T. Linteris, D Reinelt
The ban on the production of the fire suppressant CF3Br has created a need for replacement agents. Obvious alternatives are other halogenated hydrocarbons, and much research has recently been devoted to understanding their relative performance and

Prediction of HF Formation During Suppression (NIST SP 890)

November 1, 1995
Author(s)
Gregory T. Linteris, G. Gmurczyk
The acid gases hydrogen fluoride, hydrogen chloride, and hydrogen bromide (HX, where X denotes a halogen), are thought to be the most damaging and dangerous of the potential decomposition products, and much study has been devoted to determining the amounts

Effect of CF3H and CF3Br on Laminar Diffusion Flames in Normal and Microgravity

October 16, 1995
Author(s)
B. A. VanDerWege, M T. Bush, S Hochgreb, Gregory T. Linteris
Due to the ban on production of bromotrifluoromethane (CF3Br) because of its high ozone destruction potential, there has been recent interest in finding a replacement for it for fire extinguishing applications. While a variety of potential replacements are

Inhibition of Premixed Methane-Air Flames by Halon Alternatives

September 10, 1995
Author(s)
Gregory T. Linteris, L Truett
Halogenated hydrocarbons are effective and widely used as fire suppressants. Because of their suspected destruction of stratospheric ozone, however, the production of these agents, the most popular being halon 1301 (CF3Br), has been discontinued. There

Inhibition of Premixed Methane-Air Flames by Iron Pentacarbonyl

July 31, 1995
Author(s)
Gregory T. Linteris, G. Gmurczyk
Brominated fire suppressants are effective and widely used. Due to their destruction of stratospheric ozone, however, the production of these chemical was halted in January 1994. Although testing and development of possible substitutes is occurring, a

Parametric Study of Hydrogen Fluoride Formation in Suppressed Fires

May 9, 1995
Author(s)
Gregory T. Linteris, G. Gmurczyk
Some of the proposed replacements for CF3Br, the fluorinated hydrocarbons, are required in higher concentrations to extinguish fires and contain more halogen atoms per molecule. Since they decompose in the flame, they produce correspondingly more hydrogen
