Construction and Validation of Skeletal Combustion Mechanism for Ethylammonium Nitrate Propellant
为得到适用于硝酸乙基铵(Ethylammonium nitrate,EAN)推力器燃烧数值模拟的燃烧机理,以包含EAN蒸发产物硝酸和乙胺的详细化学反应机理为基础,构建了EAN详细燃烧机理,采用生产速率(Rate of production,ROP)分析以及敏感性分析相结合的方法对详细机理进行简化,得到了包含82组分291反应的EAN燃烧骨架机理.分别使用两种机理对乙胺着火延迟时间、层流预混火焰中组分分布以及在激波管内反应过程中组分分布,硝酸在激波…查看全部>>
In order to obtain a mechanism which is suitable for numerical simulation of combustion process in EAN thruster,a detailed combustion mechanism for EAN is presented based on the existing mechanism containing EAN evaporation products nitric acid and ethylamine,and a skeletal mechanism for EAN combustion consisting 82 species and 291 reactions is obtained by simplifying the detailed mechanism through an integrated reduction method that contains rate of product…查看全部>>
