Shock-tube spectroscopic CO and H2O measurements during 2-methyl-1-butene combustion and chemical kinetics modeling

New CO and H2O time histories were measured for 2-Methyl-1-Butene (2M1B) behind reflected shock waves. The experimental setup was developed to simultaneously obtain carbon monoxide water from the oxidation of 2M1B in 99.5% He/Ar (20% He 79.5% Ar). experiments carried out at three different equivalence ratios (? = 0.5, 1.0, 2.0) pressures temperatures ranging 1.15 atm 1.32 1414 K 1894 K, respectively. A very limited number studies focusing on are available literature, no model is designed specifically this C5 alkene, as opposed its other isomers: 1-pentene (1-C5H10), 2-pentene (2-C5H10), 3-Methyl-1-Butene (3M1B), 2-Methyl-2-Butene (2M2B). Experimental profiles compared recent literature models containing a sub-mechanism. Numerical predictions using AramcoMech 3.0 Ruwe et al. mechanisms show that combustion behavior not well captured by these detailed kinetics models. More importantly, Cheng proposed modified version with improvements 1-C5H10 2M2B sub-mechanisms, which deteriorates mechanism's performance 2M1B. Similarly, Power had sub-mechanisms 2-C5H10, but it does reproduce any better. Dong accurate within 10% when considering only induction delay times, shows discrepancies concentration levels. present study used an updated, chemical model, mechanism able capture results suitable precision, giving best predictions.
