多部件模型在全尺寸小型双函道涡扇发动机气流数值模拟中的应用

MULTICOMPONENT MODELS IN APPLICATION TO NUMERICAL SIMULATION OF A SMALL FULL SIZED BY PASS TURBOFAN ENGINE

利用高阶单调Ｇｏｄｕｎｏｖ显／隐格式求解全尺寸小涡扇发动机Ｓ２流面上带粘性力项的非定常Ｅｕｌｅｒ方程组，获得了令人满意的稳定收敛解。对多部件模型方法在双函道小涡扇发动机气流数值模拟应用中存在的问题提出了建议。

Solved the unsteady Euler equations on the S 2 flow surfaces of a whole small by pass turbofan engine with Godunov explicit and implicit schemes of high order monotone.Satisfactory results were obtained.Some comments and suggestions were put forward upon existing problems of further application of multicomponent models to numerical turboengine simulation
