Analysis of hydrocarbon bearing fluid inclusions HCFI) using time-resolved fluorescence spectroscopy
(Society of Photo-optical Instrumentation Engineers, 2005)Hydrocarbon-bearing fluid inclusions (HCFI) are microscopic cavities within rocks that are filled with petroleum oil, the composition of which may not have changed since the trapping event. Thus, the composition of that ... -
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 ... -
A fundamental study on the pyrolysis of hydrocarbons
(Elsevier, 2021-07-10)A newly developed detailed chemical kinetic mechanism, NUIGMech1.1, is used to study the pyrolysis of C1 ¿ C7 hydrocarbons at a constant initial fuel concentration in the temperature range 900 ¿ 2000 K. We observe that, ... -
Hydrocarbon fluid inclusion fluorescence: A review
(Springer, 2007)Geological fluid inclusions are small voids that can contain a variety of liquids which are often found in natural minerals and rocks. Typically they are less than 10 micrometres in size that host fossil fluids which existed ... -
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 ... -
The oxidation of 2-butene: A high pressure ignition delay, kinetic modeling study and reactivity comparison with isobutene and 1-butene
(Elsevier, 2016-06-16)Butenes are intermediates ubiquitously formed by decomposition and oxidation of larger hydrocarbons (e.g. alkanes) or alcohols present in conventional or reformulated fuels. In this study, a series of novel igni-tion delay ... -
Oxidation of ethylene-air mixtures at elevated pressures, part 1: experimental results
(American Institute of Aeronautics and Astronautics, 2014-03-26)Shock-tube experiments have been performed to determine ignition delay times of undiluted ethylene air mixtures for temperatures from 1003 to 1401 K, at equivalence ratios from 0.3 to 2.0, and at pressures from 1.1 to 24.9 ... -
Oxidation of ethylene-air mixtures at elevated pressures, part 2: chemical kinetics
(American Institute of Aeronautics and Astronautics, 2014-03-27)A chemical kinetics submechanism for small molecular weight hydrocarbons was modified by adjusting rate constants to produce better agreement with recent ethylene ignition delay time data compared with an earlier version ... -
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 ...
