在对跨音速压气机级的动／静双叶排中的三维定常紊流流场数值的模拟中，利用三阶高分辨率ＮＮＤ格式和ＬＵ－ＳＧＳ隐式推进迭代法，既保证了流场中激波的模拟质量和粘性流动特征的正确预估，也实现了求解过程的高效率。对某单级跨音速压气机的计算及其与实验数据的对比证实了本文方法的有效性。将计算推广至多级轴流叶轮机械的情况将会是十分简便的
In simulating the numerical simulation of three-dimensional steady turbulent flow field in transonic compressor stages, the third-order high resolution NND scheme and the LU-SGS implicit propulsion iteration method are used to simulate the three-dimensional steady flow field. The correct estimation of the simulated mass and viscous flow characteristics of the shock wave also achieves a high efficiency of the solution process. The calculation of a single-stage transonic compressor and its comparison with the experimental data confirm the effectiveness of the proposed method. It will be very easy to extend the calculation to multi-stage axial-flow impeller machines
