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) ...
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 ...
Cyclopentane combustion. Part II. Ignition delay measurements and mechanism validation
(Elsevier, 2017-06-12)
This study reports cyclopentane ignition delay measurements over a wide range of conditions. The measurements were obtained using two shock tubes and a rapid compression machine, and were used to test a detailed low- and ...
An extensive experimental and modeling study of 1-butene oxidation
(Elsevier, 2017-04-13)
In this study, a series of ignition delay time (IDT) experiments of 1-butene were performed in a high-pressure shock tube (HPST) and in a rapid compression machine (RCM) under conditions of relevance to practical combustors. ...
A comprehensive iso-octane combustion model with improved thermochemistry and chemical kinetics
(Elsevier, 2017-02-05)
Iso-Octane (2,2,4-trimethylpentane) is a primary reference fuel and an important component of gasoline fuels. Moreover, it is a key component used in surrogates to study the ignition and burning characteristics of gasoline ...
Assessing the predictions of a NOx kinetic mechanism on recent hydrogen and syngas experimental data
(Elsevier, 2017-05-02)
A detailed chemical kinetic mechanism has been developed to describe the pyrolysis and oxidation of the hydrogen/NOx and syngas/NOx systems. The thermodynamic data of nitrogenous compounds have been updated based on the ...
Uncertainty quantification of a newly optimized methanol and formaldehyde combustion mechanism
(Elsevier, 2017-09-27)
A detailed reaction mechanism for methanol combustion that is capable of describing ignition, flame propagation and species concentration profiles with high accuracy has been developed. Starting from a modified version of ...
Theoretical kinetics analysis for Ḣ atom addition to 1,3-Butadiene and related reactions on the Ċ4H7 potential energy surface
(American Chemical Society, 2017-09-08)
The oxidation chemistry of the simplest conjugated hydrocarbon, 1,3-butadiene, can provide a first step in understanding the role of polyunsaturated hydrocarbons in combustion and, in particular, an understanding of their ...
Autoignition characteristics of oxygenated gasolines
(Elsevier, 2017-08-14)
Gasoline anti-knock quality, defined by the research and motor octane numbers (RON and MON), is important for increasing spark ignition (SI) engine efficiency. Gasoline knock resistance can be increased using a number of ...
CO and H2O time-histories in shock-heated blends of methane and ethane for assessment of a chemical kinetics model
(ASME The American Society of Mechanical Engineers, 2017-09-13)
Methane and ethane are the two main components of natural gas and typically constitute more than 95% of it. In this study, a mixture of 90% CH4/10% C2H6 diluted in 99% Ar was studied at fuel lean (equiv. ratio = 0.5) ...
