An experimental and kinetic modeling study of the ignition delay characteristics of binary blends of ethane/propane and ethylene/propane in multiple shock tubes and rapid compression machines over a wide range of temperature, pressure, equivalence ratio, and dilution

In this work, the ignition delay time characteristics of C2 – C3 binary blends gaseous hydrocarbons including ethylene/propane and ethane/propane are studied over a wide range temperatures (750 2000 K), pressures (1 135 bar), equivalence ratios (φ = 0.5 2.0) dilutions (75 90%). A matrix experimental conditions is generated using Taguchi (L9) approach to cover for validation chemical kinetic model. The data recorded low- high-pressure shock tubes two rapid compression machines (RCM) include all designed conditions. These novel experiments provide direct model, NUIGMech1.1, its performance characterized via statistical analysis, with agreement between model being within ~ 26.4% studied, which comparable general absolute uncertainty applied facilities (~ 20%). Sensitivity flux analyses allow key reactions controlling behavior be identified. Subsequent performed identify those important pure fuel components blended fuels, synergistic/antagonistic blending effects therefore identified overall NUIGMech1.1 correlations in good data.
