Title

Methane And Dimethyl Ether Oxidation At Elevated Temperatures And Pressures

Abstract

Autoignition and oxidation of Methane (CH4) and Dimethyl Ether (DME or CH3OCH3) mixtures in air were studied in a shock tube over a wide range of equivalence ratios at elevated temperatures and pressures. These experiments were conducted in the reflected shock region with pressures ranging from 0.8-36.1 atmospheres, temperatures ranging from 912-1491 K, and equivalence ratios of 2.0, 1.0, 0.5, and 0.3. Ignition delay times were obtained from shock tube endwall pressure traces for fuel mixtures of CH4/CH3OCH3 in ratios of 80/20 and 60/40. Under all conditions, the 60/40 fuel mixture produced shorter ignition delay times. The experimental results should serve as a validation for detailed chemical kinetics mechanisms.
