| 摘 要： | 以设计工况下离心压气机内部动静部件耦合的非定常流场为研究对象，采用ＰＩＳＯ算法求解了包含绝对速度与相对速度的、统一形式的运动方程组。计算结果与试验测量结果比较，说明计算结果是可靠的；计算结果同时说明，只有采用非定常算法，才有可能较好地描述动静部件耦合的流场。

| Abstract: | Unsteady flow field in centrifugal fan due to rotor/ stator interaction under designed condition is studied. The PISO algorithm is applied to solve the kinetic equations with absolute and relative velicities. Compared with the experimental data, the numerical method for unsteady flow is proved to be reliable. Moreover the numerical results illustrate only unsteady scheme can investigate the flow field properly. |
