Cosolvent-assisted Spray Pyrolysis for the Generation of Metal Particles

July 1, 2003
Author(s)
Valeri I. Babushok, S H. Ehrman, Thomas Germer, Jae H. Kim, George W. Mulholland
A co-solvent assisted spray pyrolysis process was developed for the formation of pure metal particles from metal salt precursors without the direct addition of hydrogen or other reducing gas. Generation of pure copper and nickelparticles from aqueous

Effective Non-Toxic Metallic Fire Suppressants. Final Report (NISTIR 6875)

May 1, 2002
Author(s)
Gregory T. Linteris, M D. Rumminger, Valeri I. Babushok, H K. Chelliah, T 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

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

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

Premixed Flame Inhibition by Manganese and Tin Compounds

April 1, 2001
Author(s)
Gregory T. Linteris, Vadim D. Knyazev, Valeri I. Babushok
In this work we presented the first experimental measurements of influence of manganese- and tin-containing compounds (MMT, TMT0 on burning velocity of methane/air flames. We have also developed kinetic models describing the inhibition mechanisms

Chlorination in Combustion Systems

December 1, 2000
Author(s)
Wing Tsang, Valeri I. Babushok
This paper is concerned with the formation of polychorinated organics in the gas phase in combustion systems. The results are derived from simulation studies with inputs from the fundamental kinetics of single step thermal gas phase reactions. Attention is

Inhibitor Rankings for Alkane Combustion

December 1, 2000
Author(s)
Valeri I. Babushok, Wing Tsang
The effect of hydrocarbon fuel type on the ranking of inhibitor effectiveness has been investigated through computer simulations. The approach involves carrying out sensitivity analysis on the detailed kinetics of the combustion of C 1-C 4 hydrocarbons. It

Marginally Flammable Materials: Burning Velocity of Trans-Dichloroethylene

September 10, 2000
Author(s)
Gregory T. Linteris, Valeri I. Babushok
The overpressure dynamics and explosion hazard of commodity materials under full-scale conditions are often assessed through laboratory measurements of their laminar burning velocity. We present the first measurements of the flame speed of trans-1,2

Chemical Limits to Flame Inhibition

December 1, 1998
Author(s)
Valeri I. Babushok, Wing Tsang, Gregory T. Linteris, D Reinelt
This paper deals with the ultimate limits of chemical contributions to flame inhibition. Particular attention is focussed on the inhibition cycles which regenerate the inhibitor. This leads to the definition of an idealized "perfect" inhibition cycle. It

Condensed Phase Phenomena in Commodity Polymers Undergoing Degradation/Gasification.

November 2, 1998
Author(s)
Valeri I. Babushok, Thomas J. Ohlemiller, Takashi Kashiwagi
A series of degradation/gasification experiments has been conducted to better understand the condensed phase processes during burning of commodity polymers such as polypropylene (PP), polyethylene (PE), and polystyrene (PS). Understanding the molten
