| 摘 要： | 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。

| Abstract: | In this paper, the blade optimization effect has been investigated by numerical method under the condition of unsteady flow. The optimization of blade is performed by the inverse problem algorithm of steady flow. The rotor/stater interaction is considered under the condition of unsteady flow. Based on Navier-Stokes equations, the solution of unsteady flow is completed with the method of dividing into multiple computational regions. The computed results show that the blade optimized according to steady flow has also better aerodynamic performance in the condition of unsteady flow. |
