| 摘 要： | 对跨音速压气机叶片排内具有复杂三维激波的紊流流场所进行的数值分析，采用了空间三阶精度无波动格式以保证对紊流特征的正确模拟，利用ＬＵ－ＳＧＳ算法避免了一般隐式算法的繁琐运算，使之与显式方法推进一步的运算工作量基本相当，从而构成了一种既准确又高效的跨音速压气机紊流流动数值求解系统。计算与实验进行了对比，结果是令人满意的。

| Abstract: | It is found that a three or high order accurate high-resolution scheme may be more suitable for the correct prediction of turbulent flow field characteristics in the numerical analysis of three-dimensional turbulent shocked flo w in t ransonic compressor blade row.T he conver gence of the three-dimensional turbulent f low cal culation can be remarkably sped up by using the implicit LU-SG Salgo rithm,which is unconditionally stable.A detailed comparison between numerical solutions and experimental data indicates that their agreement is quite satisfactory. |
