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 ...
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 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 ...
An ignition delay time and chemical kinetic modeling study of the pentane isomers
(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 ...
Revisiting the kinetics and thermodynamics of the low-temperature oxidation pathways of alkanes: a case study of the three pentane isomers
(American Chemical Society, 2015-03-23)
This paper describes our developing understanding of low-temperature oxidation kinetics. We have investigated the ignition of the three pentane isomers in a rapid compression machine over a wide range of temperatures and ...
Using rapid compression machines for chemical kinetics studies
(Elsevier, 2014-04-26)
Rapid compression machines (RCMs) are used to simulate a single compression stroke of an internal combustion engine without some of the complicated swirl bowl geometry, cycle-to-cycle variation, residual gas, and other ...
An RCM experimental and modeling study on CH4 and CH4/C2H6 oxidation at pressures up to 160 bar
(Elsevier, 2017-06-13)
The oxidation of CH4 and CH4/C2H6 mixtures were studied at pressures relevant to knocking in large bore natural gas engines. The experiments were carried out in a rapid compression machine (RCM) at end of compression (EOC) ...
Simplified approach to the prediction and analysis of temperature inhomogeneity in rapid compression machines
(American Chemical Society, 2015-11-03)
Substantial progress has been made in understanding and reducing temperature inhomogeneity in rapid compression machines (RCMs) with the help of computational modeling. To date, however, it has not been possible to investigate ...
Chemical kinetics of hydrogen atom abstraction from allylic sites by 3O2; Implications for combustion modelling and simulation
(American Chemical Society, 2017-02-14)
ABSTRACT: Hydrogen atom abstraction from allylic C−H bonds by molecular
oxygen plays a very important role in determining the reactivity of fuel molecules
having allylic hydrogen atoms. Rate constants for hydrogen atom ...
Modeling nitrogen species as pollutants: thermochemical influences
(American Chemical Society, 2016-08-22)
To simulate emissions of nitrogen-containing compounds in practical combustion environments, it is necessary to have accurate values for their thermochemical parameters, as well as accurate kinetic values to describe the ...
