| 摘 要： | 进一步发展了非定常雷诺平均N—S方程求解程序，并基于影响系数法，在三种不同振型下就进口气流角对三维涡轮振荡叶片绕流的影响进行了数值模拟研究。数值模拟结果表明，所发展的程序对振荡叶栅流动模拟具有较好的精度；进口气流角对振荡叶栅内部非定常流动以及叶片表面的非定常气动力有着较为重要的影响，且在不同模态下，进口气流角对振荡叶片非定常流动的影响规律表现不同。

| Abstract: | Numerical simulation of 3D unsteady viscous flow around oscillating turbine blades was car-ried out with influence coefficient method and the corresponding numerical simulation code.The numeri-cal results of three different mode shapes with emphasis on incidence angle are in well agreement with the experimental data.The numerical results also show that incidence angle has an important effect on the unsteady flow and the pressure distribution of oscillating blades under different mode shapes. |

| Keywords: | oscillating cascade unsteady flow mode shape numerical simulation incidence angle |
