| Abstract: | The application of the implicit dual time step approach to the prediction of three dimensional unsteady flow through the stage of compressor is presented, and the effects of mesh density and real time step on the simulated results are investigated. The numerical results show that the effect of mesh density and real time step is larger, and there are complex unsteady flow structures in the blade passages. |

| Keywords: | dual time step approach unsteady flow turbomachinery |
