High-temperature oxidation of propanol isomers in the mixtures with N2O at high Ar dilution conditions

Research output: Contribution to journalArticle

Abstract

This work provides, for the first time, new information regarding the kinetics interaction between N2O and propyl alcohol isomers. To this end, the formation and consumption of atomic oxygen were measured behind the reflected shock waves using Atomic Resonance Absorption Spectroscopy (ARAS) technique for 1–10 ppm n- i-propanol + 10 ppm N2O + Ar mixtures, at 2–3 bar and over a wide temperature range of 1700–3200 K. The Konnov and POLIMI detailed combustion mechanisms were assessed against experimental data and also employed to study the main reactions influencing the oxidation dynamics of fuel mixtures under the investigated conditions. The study highlighted a certain difficulty by the models tested in predicting the formation of atomic oxygen at T < 2000 K. The rate of production and the sensitivity analysis was performed with the attempt to identify the most important reactions involved in the process oxidation for future kinetic model refinements.
