에탄올 점화 과정에 관한 충격관 실험 및 모델 연구

Abstract

The ignition of ethanol-oxygen-argon mixture was studied in reflected shock waves over the tem-perature range of 1281-1625 K and the pressure range of 0.69-1.06 bar. The ignition delay time was measured by thesudden increase of pressure profile and the radiation emitted by OH radicals. The relationship between the ignition delaytime and the concentrations of ethanol and oxygen was determined in the form of mass-action expressions with an Arrhe-nius temperature dependence. In contrast to the behavior observed in methanol, ethanol acts to inhibit rather than accel-erate its own ignition. Several kinetic mechanisms proposed for ethanol oxidation at high temperatures have been testedby the computer simulation.
