The impact of the third O2 addition reaction network on ignition delay times of neo-pentane
(Elsevier, 2020-08-27)
We studied the oxidation of neo-pentane by combining experiments, theoretical calculations, and mechanistic developments to elucidate the impact of the 3rd O2 addition reaction network on ignition delay time predictions. ...
An experimental and detailed kinetic modeling study of the pyrolysis and oxidation of allene and propyne over a wide range of conditions
(Elsevier, 2021-07-27)
Allene and propyne are important intermediates in the pyrolysis and oxidation of higher hydrocarbon fuels, and they are also a major source of propargyl radical formation, which can recombine into different C 6 H 6 isomers ...
An experimental and kinetic modeling study of the ignition delay characteristics of binary blends of ethane/propane and ethylene/propane in multiple shock tubes and rapid compression machines over a wide range of temperature, pressure, equivalence ratio, and dilution
(Elsevier, 2021-03-02)
In this work, the ignition delay time characteristics of C2 – C3 binary blends of gaseous hydrocarbons including ethylene/propane and ethane/propane are studied over a wide range of temperatures (750 – 2000 K), pressures ...
Understanding the antagonistic effect of methanol as a component in surrogate fuel models: A case study of methanol/n-heptane mixtures
(Elsevier, 2021-01-19)
Methanol is a widely used engine fuel, blend component, and additive. However, no systematic auto-ignition data or laminar flame speed measurements are available for kinetic studies of the effect of methanol as a blending ...
A comprehensive experimental and kinetic modeling study of 1-hexene
(Elsevier, 2021-06-13)
It is important to understand the low-temperature chemistry of 1-hexene as it is used as a representative alkene component in gasoline surrogate fuels. Ignition delay times (IDTs) of 1-hexene measured in rapid compression ...
A fundamental study on the pyrolysis of hydrocarbons
(Elsevier, 2021-07-10)
A newly developed detailed chemical kinetic mechanism, NUIGMech1.1, is used to study the pyrolysis of C1 ¿ C7 hydrocarbons at a constant initial fuel concentration in the temperature range 900 ¿ 2000 K. We observe that, ...
A comprehensive experimental and improved kinetic modeling study on the pyrolysis and oxidation of propyne
(Elsevier, 2020-09-15)
To improve our understanding of the combustion characteristics of propyne, new experimental data for ignition delay times (IDTs), pyrolysis speciation profiles and flame speed measurements are presented in this study. IDTs ...
An experimental and kinetic modeling study of the auto-ignition of natural gas blends containing C1–C7 alkanes
(Elsevier, 2020-07-16)
Ignition delay time measurements for multi-component natural gas mixtures were carried out using a rapid compression machine at conditions relevant to gas turbine operation, at equivalence ratios of 0.5–2.0 in ‘air’ in the ...
Hindered rotor benchmarks for the transition states of free radical additions to unsaturated hydrocarbons
(Royal Society of Chemistry, 2020-11-03)
The hindered internal rotors of 32 transition states (TSs) formed through four free radicals, namely methyl, vinyl, ethyl, methoxy (CH3, C2H3, C2H5, CH3) additions to acetylene, ethylene, allene, propyne, and propene ...
