摘要
借助现代计算流体动力学（ＣＦＤ）技术讨论应用数值方法来模拟叶轮机械叶栅内部的实际流动，以期获取大量真实可靠的流动信息。据此，建立一种结合湍流模型的二阶精度稳式矢通量单步差分格式并用来求解叶栅的跨音流场，数值试验表明：该方法具有精度较高、稳定性好、计算量少、收敛快等优点，在流场的计算中，较好地捕获了激波，与实验数据比较，结果令人满意。
Described in the paper is a numerical algorithm based on the latest development of Computional Fluid Dynamics technology for real flow of turbomachinery cascade. More details of flow information and many practical laws for modern turbomachery design can be obtained. Numerical calculations demonstrate clearly that a one - step two - order accuracy Implicit Flux Vector Splitting (IFVS) scheme has obvious superiority in aspeCts of accuracy and calculation. In the case of 2- D fransonic cascade flows, shock wave is exactly captured and results are satisfactory.
