Autoignition of ethanol in a rapid compression machine
(Elsevier, 2013-12-09)Ethanol is a renewable source of energy and significant attention has been directed to the development of a validated chemical kinetic mechanism for this fuel. The experimental data for the autoignition of ethanol in the ... -
An autoignition study of hydrogen and natural gas mixtures under gas turbine relevant conditions in a rapid compression machine
(2013-11-14)This study presents an experimental and modelling investigation of the ignition of hydrogen and natural gas mixtures. These mixtures were chosen due to their relevancy to the gas turbine industry. A detailed chemical ... -
Critical evaluation of thermochemical properties of C-1-C-4 species: updated group-contributions to estimate thermochemical properties
(AIP Publishing, 2015-01-05)A review of literature on enthalpies of formation and molar entropies for alkanes, alkenes, alcohols, hydroperoxides, and their associated radicals has been compiled and critically evaluated. By comparing literature values, ... -
Decomposition studies of isopropanol in a variable pressure flow reactor
(Oldenbourg Verlag, 2015-04-01)Alternatives to traditional petroleum derived transportation fuels, particularly alcohols, have been investigated increasingly over the last 5 years. Isopropanol has received little attention despite bridging the gap between ... -
A detailed chemical kinetic modeling, ignition delay time and jet-stirred reactor study of methanol oxidation
(Elsevier, 2016-01-29)A shock tube (ST) and a rapid compression machine (RCM) have been used to measure new ignition delay times for methanol oxidation over a wide range of pressures (2-50 atm) and equivalence ratios (0.5, 1.0, and 2.0). These ... -
Development of a Chemical Kinetic Mechanism for Small Hydrocarbons
(2014-01-07)A detailed chemical kinetic mechanism has been developed to describe the oxidation of small hydrocarbon and oxygenated hydrocarbon species. In order to understand the oxidation of large hydrocarbon and oxygenated hydrocarbon ... -
Experimental and kinetic modeling study of 2-methyl-2-butene: allylic hydrocarbon kinetics
(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
(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 ... -
Experimental and kinetic modeling study of the shock tube ignition of a large oxygenated fuel: tri-propylene glycol mono-methyl ether
(Elsevier, 2015-05-13)Tri-propylene glycol monomethyl ether (TPGME) is an important oxygenated fuel additive that can be used to reduce soot in diesel engines. However, a validated chemical kinetic model that incorporates the low- to high-temperature ... -
An experimental and modeling study of shock tube and rapid compression machine ignition of n-butylbenzene/air mixtures
