发展了一种求解任意坐标系下二维Ｎ－Ｓ方程的非交错有限体积法和一种高阶ＴＶＤ对流格式。采用一种ｋ－ω湍流模型和几种不同的ｋ－ω模型对叶栅湍流分离流动进行了详细的分析。数值结果与得到的实验结果比较表明，此方法不仅精度高，而且具有较好的数值稳定性。
A non-staggered finite volume method and a high order TVD convection scheme for solving two dimensional N-S equations in arbitrary coordinate system are developed. A k-ω turbulence model and several different k-ω models were used to analyze cascade flow turbulent flow in detail. The numerical results and the experimental results obtained show that this method is not only high precision, but also has good numerical stability.
