摘要
给出了燃油在高速热气流试验系统燃烧的分布式数学模型,在GAMBIT软件中建立了系统燃烧室的几何模型,并进行了网格划分。为了了解燃油在燃烧室燃烧的性能以及系统燃烧室的出口温度分布,利用计算流体力学仿真软件FLUENT模拟了燃油在燃烧室中的燃烧,分别研究了不同油气比对燃烧室出口温度的影响和不同喷射角度对燃烧室出口温度的影响。仿真结果表明,油气比为理论油气比,喷射角度为30°左右时,燃烧室出口温度最均匀。
A distributed mathematical model of the fuel combustion in a high-speed heat-airflow system is presented.The geometrical model of the system is established and meshed using GAMBIT.In order to understand the combustion performance and the outlet temperature distribution of the combustor,the combustion of fuel in the combustor is simulated using the computational fluid dynamics software FLUENT.The influence of the fuel gas ratio and the influence of the spray angle on outlet temperature distribution of the combustor are studied,respectively.The present study laid a foundation for gas temperature control of the combustor.
