A detailed chemical kinetic modeling and experimental investigation of the low- and high-temperature chemistry of n-butylcyclohexane
Pitz, William J.; Liang, Jinhu; Kukkadapu, Goutham; Zhang, Kuiwen; Conroy, Christine; Bugler, John; Curran, Henry J. (Wiley, 2020-11-26)Chemical kinetic models of gasoline, jet, and diesel fuels and their mixtures with bioderived fuels are needed to assess fuel property effects on efficiency, emissions, and other performance metrics in internal combustion ... -
Experimental and kinetic modeling study of 2-methyl-2-butene: allylic hydrocarbon kinetics
Westbrook, Charles K.; Pitz, William J.; Mehl, Marco; Glaude, Pierre-Alexandre; Herbinet, Olivier; Bax, Sarah; Battin-Leclerc, Frederique; Mathieu, Olivier; Petersen, Eric L.; Bugler, John; Curran, Henry J. (American Chemical Society, 2015-03-20)Two experimental studies have been carried out on the oxidation of 2-methyl-2-butene, one measuring ignition delay times behind reflected shock waves in a stainless steel shock tube, and the other measuring fuel, intermediate, ... -
An experimental and kinetic modeling study of n-hexane oxidation
Zhang, Kuiwen; Banyon, Colin; Togbé, Casimir; Dagaut, Philippe; Bugler, John; Curran, Henry J. (Elsevier, 2015-09-11)Ignition delay times for n-hexane oxidation have been measured in a rapid compression machine (RCM) at stoichiometric conditions and at 15 bar. Due to the high reactivity of n-hexane and non-ideal experimental effects ... -

Bugler, John; Rodriguez, Anne; Herbinet, Olivier; Battin-Leclerc, Frédérique; Togbé, Casimir; Dayma, Guillaume; Dagaut, Philippe; Curran, Henry J. (Elsevier, 2016-06-16)Two jet-stirred reactors (JSRs) coupled to gas chromatographic and spectroscopic techniques have been utilised to detect chemical species evolved during n -pentane oxidation at 1 and 10 atm, in the temperature range 500-1100 ... -
An ignition delay time and chemical kinetic modeling study of the pentane isomers
Bugler, John; Heufer, Karl A.; Curran, Henry J. (Elsevier, 2016-10-26)Ignition delay times of n-pentane, iso-pentane, and neo-pentane mixtures were measured in two shock tubes and in a rapid compression machine. The experimental data were used as validation targets for the model described ... -
