摘    要:针对采用S2流面流场模拟软件(AES-S2),对某涡扇发动机风扇、压气机(考虑级间引气)和整机进行地面0km及高空21km低雷诺数工况下转速特性的评估和流场分析.AES-S2数值仿真模型由带有黏性项的二维欧拉方程、燃烧模型和损失模型构成;采用任意曲线坐标系,可保证复杂几何边界的计算精度;采用隐式高阶精度Godunov求解格式,数值稳定性高,可自动捕捉激波.仿真结果表明:AES-S2计算稳定性好,收敛速度快;风扇和压气机的计算精度高于整机;整机二维计算满足工程精度需求,可为部件研制和整机部件匹配提供性能参数依据. 

关 键 词:数值模拟   涡扇发动机   风扇/压气机   二维   引气

Abstract:To assess the fan,compressor and whole engine performance of a turbofan engine on 0 km and 21 km operating conditions,considering air bleeding in compressor,an aero-engine S2 stream-surface flow simulation software(AES-S2) was used.AES-S2 numerical simulation model consists of two-dimensional Euler equation,combustion model and loss model.A body fitted coordinate system was used to adapt the complex geometric boundaries.The implicit higher-order Godunov scheme has the characteristic of shock capturing and g...
Keywords:numerical simulation  turbofan engine  fan/compressor  two-dimensional  air bleeding
