A Comprehensive Experimental and Simulation Study of Ignition Delay Time Characteristics of Single Fuel C1–C2 Hydrocarbons Over a Wide Range of Temperature, Pressure, Equivalence ratio, and Dilution

A comprehensive experimental and modelling study of the ignition delay time (IDT) characteristics of some single prominent C1–C2 hydrocarbons such as methane, ethane, and ethylene have 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 of the available exper...
