Pressure Dependence and Branching Ratios in the Decomposition of 1-Pentyl Radicals: Shock Tube Experiments and Master Equation Modeling

February 22, 2012

Author(s)

Iftikhar A. Awan, Donald R. Burgess Jr., Jeffrey A. Manion

The decomposition and intramolecular H-transfer isomerization reactions of the 1 pentyl radical have been studied at temperatures of 900 K to 1050 K and pressures of 0.8 bar to 6 bar using the single pulse shock tube technique and additionally investigated

Annual Report to Sponsor: Understanding Unwanted Combustion Enhancement by Potential Halon Replacements

November 23, 2011

Author(s)

Donald R. Burgess Jr., Jeffrey A. Manion

The computations reported in this paper were done in conjunction with an experimental study involving single pulse shock tube measurements of the thermal decomposition of three chloroalkanes, and that work is reported in an accompanying preceding paper

Standard Reactions for Comparative Rate Studies: Experiments on the Dehydrochlorination Reactions of 2 Chloropropane, Chlorocyclopentane and Chlorocyclohexane

November 23, 2011

Author(s)

Iftikhar A. Awan, Donald R. Burgess Jr., Wing Tsang, Jeffrey A. Manion

Single pulse shock tube studies of the thermal dehydrochlorination reactions (chlorocyclopentane → cyclopentene + HCl) and (chlorocyclohexane → cyclohexene + HCl) at temperatures of 843 to 1021 K and pressures of 1.4 to 2.4 bar have been carried out using

Stirred-Reactor Simulations of Enhanced Reaction in the Presence of Fire Suppressants

Author(s)

Gregory T. Linteris, Donald R. Burgess Jr., Fumiaki Takahashi, Viswanath R. Katta, Oliver Meier

Several agents are under consideration to replace CF3Br in suppressing aircraft cargo bays fires. In a Federal Aviation Administration performance test simulating the explosion of an aerosol can, however, the replacements, when added at sub-inerting

Kinetic Barriers of H-Atom Transfer Reactions in Alkyl, Allylic, and Oxoallylic Radicals, as Calculated by Composite Ab Initio Methods

February 18, 2009

Author(s)

Carrigan J. Hayes, Donald R. Burgess Jr.

Composite ab initio and density functional theory (DFT) methods were used to explore internal hydrogen-atom transfers in a variety of primary, secondary, and tertiary alkyl and functionalized radicals with implications for combustion environments. The

Exploring the Oxidative Decompositions of Methyl Esters: Methyl Butanoate and Methyl Pentanoate as Model Compounds for Biodiesel

October 7, 2008

Author(s)

Carrigan J. Hayes, Donald R. Burgess Jr.

Methyl esters are commonly used as surrogates for complex biofuel chemistry; this utility necessitates development of combustion mechanisms for these species. A pathway accounting for early CO2 production in the combustion of methyl esters, using methyl
