本文对叶型优化在非定常流动条件下的效果进行数值研究。叶型优化基于比较成熟的在定常流动条件下的反问题解法，非定常流动则考虑到动静叶栅之间的相互作用，非定常流动的求解在Ｎ－Ｓ方程的基础上采用分区计算的方法来完成。数值计算的结果表明，定常流动条件下优化得到的叶型在非定常流动条件下同样具有较好的气动性能。
In this paper, the effect of leaf-type optimization under unsteady flow conditions is numerically investigated. The optimization of the leaf type is based on the more mature inverse problem solution under steady flow conditions. The unsteady flow takes into account the interaction between the moving and stationary cascades. The unsteady flow solution is based on the N-S equation and is partitioned To be done. The numerical results show that the aerodynamically optimized aerodynamic model under steady flow conditions also has good aerodynamic performance under unsteady flow conditions.
