Final Report: Effective Non-Toxic Metallic Fire Suppressants

May 1, 2002
Author(s)
Gregory T. Linteris, M D. Rumminger, Valeri I. Babushok, Harsha K. Chelliah, A K. Lazzarini, P N. Wanigarathne
The purpose of the project was to: a.) identify which metal species would be effective flame inhibitors, and then b.) attempt to find non-toxic forms of the metal which could be used. Very early in the project, however, we determined that metal species-in

Inhibition of Premixed Methane Flames by Manganese and Tin Compounds

May 1, 2002
Author(s)
Gregory T. Linteris, Vadim D. Knyazev, Valeri I. Babushok
The first experimental measurements of influence of manganese- and tin-containing compounds (MMT, TMT) on burning velocity of methane/air flames are presented. Comparisons with Fe(CO) 5 and CF 3Br demonstrate that manganese and tin-containing compounds are

Particle Formation in Laminar Flames Inhibited by Metals

March 1, 2002
Author(s)
Gregory T. Linteris, M D. Rumminger
Some organometallic compounds of iron are two orders of magnitude more effective at volume fraction than CF 3Br in premixed flames, an order of magnitude more effective in counterflow diffusion flames. The condensation of active gas-phase iron-containing

Inhibition of Premixed and Non-Premixed Flames with Fine Droplets of Water and Solutions

January 1, 2002
Author(s)
Harsha K. Chelliah, A K. Lazzarini, P N. Wanigarathne, Gregory T. Linteris
Inhibition/extinction of premixed and non-premixed methane-air flames with fine-droplets of water and solutions containing several chemical agents are investigated experimentally. While solutions allow delivery of much higher concentrations of chemical

Temperature Regions of Optimal Chemical Inhibition of Premixed Flames

January 1, 2002
Author(s)
M D. Rumminger, Valeri I. Babushok, Gregory T. Linteris
Chemically-active fire suppressants may, due to their properties or the means by which they are added to flames, have strong inhibition effects in particular locations in a flame. To study the spatial effects of chemically-active inhibitors, numerical

Physical and Chemical Aspects of Fire Suppression in Extraterrestrial Environments

May 22, 2001
Author(s)
Fumiaki Takahashi, Gregory T. Linteris, Vishwanath R. Katta
A fire, whether in a spacecraft or in occupied spaces on extraterrestrial bases, can lead to mission termination or loss of life. While the fire-safety record of US space missions has been excellent, the advent of longer duration missions to Mars, the moon

Trioxane-Air Counterflow Diffusion Flames in Normal and Microgravity

May 22, 2001
Author(s)
Gregory T. Linteris, M D. Rumminger, D L. Urban
Trioxane, a weakly bound polymer of formaldehyde (C3H6O3, melting point 61 deg C, boiling point 115 deg C), is a uniquely suited compound for studying material flammability. Like many of the more commonly used materials for such tests (e.g. delrin

Premixed Flame Inhibition by Manganese and Tin Compounds

April 24, 2001
Author(s)
Gregory T. Linteris, Vadim D. Knyazev, Valeri I. Babushok
Flame inhibition data exist for a few metallic compounds (Fe(CO)5, Pb(C2H5)4, CrO2Cl2) which show them to be one or two orders of magnitude more effective than halon 1301 at reducing the burning velocity of premixed methane-air flames. Little burning
