基于双分子反应模型的JP-10燃烧机理分析研究

摘要

为了进一步研究JP-10燃料在火箭发动机燃烧室中的燃烧机理,基于双分子反应模型,用逆流燃烧实验数据做支撑,对Arrhenius方程进行修正,并求取参数;在此基础上改进燃烧模型,对JP-10液料燃烧过程进行数值模拟,并与实验值进行比对.研究结果表明:对于JP-10燃料的燃烧机理,可以采用实验与数值计算相结合的方法对燃烧速率封闭模型进行升级,并通过已有实验数据验证了其对湍流燃烧模拟的可行性.%In order to further understand the combustion mechanism of the JP-10 droplet in the engine combustion chamber, based on the bimolecular reaction collision model and by means of mathematical modeling, we simulated the combustion process of the JP-10 droplet. The arrhenius equation parameters of burning JP-10 according to existing experimental data is solved. In order to make sub-grid scale combustion models to the closure of liquid spray combustion LES equations more accurate.
