摘    要:分析了航空发动机各部件内部流动的S2流面数学模型,进行了整机流场仿真计算.求解过程采用具有TVD性质的高阶Godunov格式,具有良好的数值稳定性和激波捕获能力.考虑了粘性效应以及二次流损失对于部件及整机性能的影响.对于部件间及叶排间的参数传递,采用了一种完全守恒的处理方法,保证了数值通量的连续性.仿真结果与试验数据的对比证明该方法具有较高的精度.

关 键 词:航空、航天推进系统  航空发动机  数值仿真  S2流面  流场计算

Abstract:Mathematical models for each component of aero engine based on S2 surface theory were analyzed.A full engine S2 flow simulation was performed using this method.High order Godunov's scheme was used,presenting good numerical stability and shock capturing capability.Viscous effects and secondary flow losses were treated as source terms.Their influence on the components and full engine system's performance were estimated effectively.A conservative process was taken to handle the parameter transfer between neighboring domains,ensuring the consistency of flux.The method features high accuracy by comparing the simulation and experimental results.
Keywords:aerospace propulsion system  aero engines  numerical simulation  S2 surface  flow field calculation
