Experimental and modeling study of the pyrolysis and oxidation of an iso-paraffinic alcohol-to-jet fuel

摘要

Single pulse shock tube experiments were conducted to determine the pyrolytic and oxidative decomposition products of an alcohol-to-jet fuel (ATJ) composed primarily of about 90% iso-dodecane. Experiments were performed at 4 bar nominal pressure, 2 ms nominal reaction time, and temperatures ranging from 900K to 1550 K. For oxidation, the equivalence ratio was 0.27, Gas chromatography (GC) was used to analyze the products of the chemical reactions and to determine their mole fractions. The experimental results were compared against mole fractions computed using a detailed iso-alkane kinetic model, developed for the present study. The model was able to accurately reproduce the experimental results of both ATJ pyrolysis and oxidation. The experimental data and the kinetic model developed in the current study shall aid in progress in understanding the oxidation of the alternative jet fuels.
