为了探究燃油配置对加力燃烧室湍流燃烧过程的影响，设计了三种喷油比例和两种喷嘴布局的配置方案，基于燃油燃烧详细反应机理对加力燃烧室湍流燃烧状况进行数值研究。通过燃烧室内燃油的压力、温度、速度、湍动能的分布探究了燃烧的特性和机理，考察了加力燃烧室燃油、氧气和燃烧产物的分布情况。引入温度均匀性系数和燃烧效率，对加力燃烧室燃烧特性进行综合评价。结果表明：适当提高外圈喷油比例有利于改善外圈燃烧过程，提高尾喷管出口温度和整体燃烧效率；喷嘴V型布置时中圈燃烧产生的热量促进内圈和外圈的燃烧过程，燃烧性能更好。
Abstract：In order to explore the influence of fuel configuration on the turbulent combustion process of afterburner,the configuration schemes of three fuel injection ratio and two nozzle layouts were designed,and the turbulent combustion status of afterburner was numerically studied based on the detailed fuel combustion reaction mechanism.The fuel in combustion characteristics and mechanism were analyzed through the pressure,temperature,velocity and turbulent dynamic energy distributions.The distributions of fuel,oxygen and combustion products in afterburner were investigated.The temperature uniformity coefficient and combustion efficiency were introduced,and the combustion characteristics of afterburner were comprehensively evaluated.The results showed that appropriately increasing the fuel injection ratio of outer-ring was conducive to improve the combustion process of outer-ring,increases the outlet temperature of tail nozzle and the overall combustion efficiency.In the nozzle V-type layout,the heat generated by the middle-ring combustion promoted the combustion processes of inner-ring and outer-ring,and the overall combustion performance was better.
