摘要
本文采用分区、并行计算方法求解二维Ｅｕｌｅｒ方程，对１．５级透平叶片排内的非定常流场干涉进行了数值模拟，并探讨了透平叶栅静叶周向布局对透平级性能的影响．计算结果表明，本文的处理和计算方法是合理有效的，并且发现存在静叶最佳周向布局，此时透平级的性能最好．本文所得结论对于透平级的优化设计是有意义的。
This paper presents the results of two-dimensional numerical simulations of unsteady inter- action in 1 1/2 stage turbine cascades, and studies the effects of circumferentially clocking of turbine stator rows on turbine performance. It shows that the management and calculating method used can provide reasonable and acceptable results. It is found that there is optimum stator circumferential position where turbine stage has maximum performance. The conclusion is useful for optimal design of turbine stage.
