Abstract:

A comprehensive experimental and modeling study of the ignition delay time (IDT) characteristics of some single prominent C1–C2 hydrocarbons including methane, ethane, and ethylene has been performed over a wide range of temperatures (∼800–2000 K), pressures (∼1–80 bar), equivalence ratios (∼0.5–2.0), and dilutions (∼75–90%). An extensive literature review was conducted, and available data were extracted to create a comprehensive database used in our simulations. Based on existing literature data, an experimental matrix was designed using the Taguchi approach (L9) in order to identify and complete the experimental matrix required to generate a comprehensive validation set necessary for validation of a chemical kinetic model. The required IDTs were recorded using a high-pressure shock tube for shorter IDTs and a rapid compression machine for longer times, which encompass high- and low-temperature ranges, respectively. The predictions of a C3-NUIG mechanism have been compared with all...

Abstract:

Ignition delay times for 1,3-butadiene oxidation were measured in five different shock tubes and in a rapid compression machine (RCM) at thermodynamic conditions relevant to practical combustors. The ignition delay times were measured at equivalence ratios of 0.5, 1.0, and 2.0 in 'air' at pressures of 10, 20 and 40 atm in both the shock tubes and in the RCM. Additional measurements were made at equivalence ratios of 0.3, 0.5, 1.0 and 2.0 in argon, at pressures of 1, 2 and 4 atm in a number of different shock tubes. Laminar flame speeds were measured at unburnt temperatures of 295 K, 359 K and 399 K at atmospheric pressure in the equivalence ratio range of 0.6-1.7, and at a pressure of 5 atm at equivalence ratios in the range 0.6-1.4. These experimental data were then used as validation targets for a newly developed detailed chemical kinetic mechanism for 1,3-butadiene oxidation.A detailed chemical kinetic mechanism (AramcoMech 3.0) has been developed to describe the combus...

Abstract:

A comprehensive experimental and kinetic modeling study of the ignition delay time (IDT) characteristics of some binary blends of C1–C2 gaseous hydrocarbons such as methane/ethylene, methane/ethane, and ethane/ethylene was performed over a wide range of composition (90/10, 70/30, 50/50%), temperature (∼800–2000 K), pressure (∼1–40 bar), equivalence ratio (∼0.5–2.0), and dilution (∼75–90%). An extensive literature review was conducted, and available data were extracted to create a comprehensive database for our simulations. Based on the existing literature data, an experimental matrix was designed using the Taguchi approach (L9) in order to identify and complete the experimental matrix required to generate a comprehensive experimental IDT set necessary for the validation of a chemical kinetic model. The required high- and low-temperature IDTs were collected using low-/high-pressure shock tubes and rapid compression machines, respectively. The predictions of NUIGMech1.0 are examined v...
