| 摘 要： | 整机二维仿真模型由带有粘性项的二维欧拉方程,燃烧模型和损失模型构成.利用任意曲线坐标系来适应复杂几何边界计算,采用隐式高阶精度Godunov格式求解非定常欧拉方程,能够自动捕捉激波,数值稳定性高.计算的总性能参数与设计值对比显示:单部件的仿真精度高于整机,涡轮仿真精度高于压气机.子午平面上的计算结果分析表明:离心压气机出口处的分离流动、燃烧室掺混孔的简化对总性能参数计算结果影响较大.

| Abstract: | two-dimensional Euler equation,combustion model and loss calculation methods were used to establish the numerical simulation model of engine.A body fitted coordinate system is used to adapt the complex geometry boundary.Unsteady Euler equation was solved by implicit high order Godunov scheme,which had the characteristic of shock capturing and good numerical stability.The data comparisons of calculation and design showed: the components simulation precision was higher than that of whole engine,the turbine si... |
