A Multiple-step Overall Kinetic Mechanism for the Oxidation of Hydrocarbons
TL;DR: In this paper, the authors presented a simplified, overall kinetic scheme which could accurately predict the major species formed and the temperature-time history (rate of heat release) of the system.
Journal ArticleDOI
Study of the High-Temperature Autoignition of n-Alkane/O/Ar Mixtures
TL;DR: In this paper, a 3.39-μm HeNe laser and multiple-pass setup is used to measure fuel in situ by absorption, and a unique correlation is presented in which the stoichiometric ignition time data for all four n-alkanes has been correlated into a single expression with an R 2 value of 0.992.
Journal ArticleDOI
A Comprehensive Chemical Kinetic Reaction Mechanism for Oxidation and Pyrolysis of Propane and Propene
TL;DR: In this article, a detailed chemical kinetic reaction mechanism was developed to describe the oxidation and pyrolysis of propane and propene, which consists of 163 elementary reactions among 4l chemical species.
Journal ArticleDOI
An Analytical Study of the Shock Tube Ignition of Mixtures of Methane and Ethane
TL;DR: In this article, an analytical study of the ignition of mixtures of methane and ethane has been carried out, using a numerical model consisting of 25 chemical species and 75 elementary chemical reactions.
Journal ArticleDOI
A rapid compression machine study of the oxidation of propane in the negative temperature coefficient regime
TL;DR: In this article, a detailed chemical kinetic model was used to simulate the effect of change in equivalence ratio and pressure, predicting that fuel-rich, high pressure mixtures ignite fastest, while fuel-lean, low-pressure mixtures ignited slowest.

Studies with a Single‐Pulse Shock Tube. I. The Cis—Trans Isomerization of Butene‐2
TL;DR: In this paper, the cis-trans isomerization of butene was investigated behind reflected shocks in a single-pulse shock tube of a novel design, and an activation energy of 65, rather than 62.8 kcal/mole, was obtained when a straight line was drawn between the high and low temperature data.
Journal ArticleDOI
Nonlinear least squares methods: A direct grid search approach
TL;DR: In this article, a simple iterative process to solve minimization problems in chemistry when the number of parameters is small, as is the case in most empirical laws, is presented.
Journal ArticleDOI
Shock Tube Ignition Delay Studies of Endothermic Fuels
Robert D. Hawthorn,Alan C Nixon +1 more
TL;DR: In this article, the effects of temperature, pressure, and fuel composition on the ignition delay of propane and methylcyclohexane starting fuels were investigated in a single-diaphragm shock tube.
Journal ArticleDOI
Kinetics and mechanisms of the thermal decomposition of propane I. The uninhibited reaction
TL;DR: In this paper, it was concluded that the reaction is largely homogeneous and occurs by a free-radical mechanism, and that the activation energy of the reaction in its first-order region was 67 1 kcal and that of the -order reaction was 54*5 koal.

Reaction and ignition delay times in the oxidation of propane
B. F. Myers,E. R. Bartle +1 more
TL;DR: In this article, an empirical correlation between reaction and ignition delay times and the pressure, temperature, and composition of propaneoxygenargon mixtures was obtained for propane-oxygen argon mixtures, and experiments were conducted by shock heating these mixtures to initial pressures and temperatures between 0.5 and 5.5 atm.
