Soot Precursors from Real Fuels: The Unimolecular Reactions of Fuel Radicals

October 16, 2008
Author(s)
Wing Tsang, Iftikhar A. Awan, William Sean McGivern, Jeffrey A. Manion
This paper describes studies aimed at defining in a quantitative fashion the cracking pattern of fuel radicals under combustion conditions. The experimental procedure involves studies using a single pulse shock tube and combining the observations with

Multichannel Decomposition and Isomerization of Octyl Radicals

October 9, 2008
Author(s)
Wing Tsang, William S. McGivern, Jeffrey A. Manion
The thermal cracking patterns from the decomposition and isomerization of octyl-1 radicals have been determined from the pyrolysis of n-octyl iodide in single pulse shock tube experiments at temperatures in the 850-1000 K range and pressures near 2 bar

Ring Expansion Reactions in the Thermal Decomposition of t-Butyl-1,3-Cyclopentadiene

November 30, 2006
Author(s)
William S. McGivern, Jeffrey A. Manion, Wing Tsang
The thermal decomposition of t-butyl-1,3-cyclopentadiene has been investigated in single pulse shock tube studies at shock pressures of 182 260 kPa and temperatures of 996 1127 K. Isobutene (2-methylpropene), 1,3-cyclopentadiene, and toluene are observed

Binary Diffusion Coefficients for Combustion Modeling

November 30, 2002
Author(s)
William S. McGivern, Jeffrey A. Manion
Recent studies have demonstrated that combustion models can be as sensitive to the binary diffusion coefficients of the fuel species as to the kinetics of major chemical reactions. We have constructed a reversed-flow chromatographic apparatus for the
