异辛烷/正庚烷/乙醇三组分燃料着火的化学动力学模型
Chemical Kinetic Model for Ignition of Three-Component Fuel Comprising iso-Octane/n-Heptane/Ethanol
摘要
Abstract
A reduced chemical kinetic mechanism for the oxidation of three-component fuel comprising iso-octane/n-heptane/ethanol has been developed. The mechanism consists of 50 species and 193 elementary reactions and emphasizes the ignition process. Using path and sensitivity analyses, the path of primary reference fuel (PRF) oxidation and major elementary reactions at high and low temperatures are given. The validated results show that the present mechanism gives good agreement with experimental data for ignition delay time predictions. Because of the few species and reactions presenting in the chemical kinetic model, the mechanism is applicable to multidimensional computational fluid dynamic (CFD) simulation of the co-combustion of gasoline with ethanol.关键词
