Modeling ignition of a heptane isomer: improved thermodynamics, reaction pathways, kinetics, and rate rule optimizations for 2-methylhexane
(American Chemical Society, 2016-03-21)
Accurate chemical kinetic combustion models of lightly branched alkanes (e.g., 2-methylalkanes) are important to investigate the combustion behavior of real fuels. Improving the fidelity of existing kinetic models is a ...
A high-pressure rapid compression machine study of n-propylbenzene ignition
(Elsevier ScienceDirect, 2013-08-28)
This study presents new ignition delay data measured in a rapid compression machine over a wide range temperature, pressure and fuel/air ratio. This data is an extension of that measured previously (D. Darcy, C.J. Tobin, ...
Optimized reaction mechanism rate rules for ignition of normal alkanes
(Elsevier, 2016-08-10)
The increasing demand for cleaner combustion and reduced greenhouse gas emissions motivates research on the combustion of hydrocarbon fuels and their surrogates. Accurate detailed chemical kinetic models are an important ...
An experimental and modeling study of shock tube and rapid compression machine ignition of n-butylbenzene/air mixtures
(Elsevier, 2013-08-28)
In our previous work (D. Darcy, C.J. Tobin, K. Yasunaga, J.M. Simmie, J. Wurmel, W.K. Metcalfe, T. Niass, S.S. Ahmed, C.K. Westbrook, H.J. Curran, Combust. Flame 159 (2012) 2219-2232), ignition delay times of n-butylbenzene ...
Towards a kinetic understanding of the NOx promoting-effect on ignition of coalbed methane: A case study of methane/nitrogen dioxide mixtures
(Elsevier, 2016-05-03)
Nitrogen dioxide (NO2) is an important impurity in coal-bed methane (CBM) and a dominant component of NOx pollution in practical engines. Its promoting effect on methane ignition has been studied in the current experimental ...
Ignition delay times, laminar flame speeds, and mechanism validation for natural gas/hydrogen blends at elevated pressures
(Elsevier, 2013-12-30)
New experimental ignition delay time data measured in both a shock tube and in a rapid compression machine were taken to determine the increase in reactivity due to the addition of hydrogen to mixtures of methane and natural ...
An experimental and modeling study of nitromethane + O2 + N2 ignition in a shock tube
(Elsevier, 2016-09-09)
The ignition of nitromethane/O-2/N-2 mixtures was investigated via shock tube experiments in the temperature range 947-1333 K at reflected shock pressures near 8, 16 and 32 atm. The ignition was recorded as the intensity ...
Theoretical and kinetic study of the hydrogen atom abstraction reactions of esters with HO2 radicals
(American Chemical Society, 2013-10-31)
This work details an ab initio and chemical kinetic study of the hydrogen atom abstraction reactions by the hydroperoxyl radical (HO2) on the following esters: methyl ethanoate, methyl propanoate, methyl butanoate, methyl ...
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 ...
The pyrolysis of 2-methylfuran: a quantum chemical, statistical rate theory and kinetic modelling study
(Royal Society of Chemistry, 2014-01-27)
Due to the rapidly growing interest in the use of biomass derived furanic compounds as potential platform chemicals and fossil fuel replacements, there is a simultaneous need to understand the pyrolysis and combustion ...
